What are joints write its type with example?
Joints aka articular surface can be defined as a point where two or more bones are connected in a human skeletal system. Cartilage is a type of tissue which keeps two adjacent bones to come in contact (or articulate) with each other. 3 Types of joints are Synovial Joints, Fibrous Joints, and Cartilaginous Joints.
Whats is a joint?
A joint is the part of the body where two or more bones meet to allow movement. Every bone in the body – except for the hyoid bone in the throat – meets up with at least one other bone at a joint. The shape of a joint depends on its function. A joint is also known as an articulation.

Why is it called joint?
The word joint ultimately originated from French, where it is an adjective meaning 'joined' (past participle of the verb joindre), derived in turn from Latin iunctus, past participle of iungere ('join'/'bind'/'yoke'). By 1821, 'joint' had become an Anglo-Irish term for an annexe, or a side-room 'joined' to a main room.

The main function of a joint is to facilitate the movement of the human body. Some additional functions of joints include providing stability to the head and pelvis, providing flexibility to the skeleton, and directing the movement of muscles at a joint.
What are joints functions?
Joints allow our bodies to move in many ways. Some joints open and close like a hinge (such as knees and elbows), whereas others allow for more complicated movement — a shoulder or hip joint, for example, allows for backward, forward, sideways, and rotating movement. Immovable, or fibrous, joints don't move.

How are bones classified 4 types?
The four principal types of bones are long, short, flat and irregular. Bones that are longer than they are wide are called long bones. They consist of a long shaft with two bulky ends or extremities. They are primarily compact bone but may have a large amount of spongy bone at the ends or extremities.

What is joint in anatomy?
Definition of Joints. A Joint or Articulation is the point where two or more bones or a bone and a cartilage are attached to the body. Joints are involved for the purpose of allowing body parts to move. Joints hold our bones together and help the skeletal system to complete its functions.
What is the term for a fluid filled joint?
Synovial joints or Diarthrosis have a fluid-filled synovial cavity and irregular dense tissues that form the articular capsule.
How many types of synovial joints are there?
There are six types of synovial joints mentioned in the table below.
What is a fibrous joint?
Fibrous Joints. Fibrous Joints do not allow movements; therefore, they are Immovable joints or Fixed joints or Synarthrosis. These joints connect by dense connective tissue consisting of primary collagen fibres and do not have a joint cavity.
What joint allows the bones to slide over each other?
Gliding Joint. This joint between two bones where the surface of the bones is almost flat enables the bones to slide over each other. Gliding joint allows sliding movements. Gliding joints are found between the carpals.
How many bones are there in the human body?
Joints: Did you know that an adult human has 206 bones in the body? How are these bones attached to each other? Have we ever thought about how we can walk? What helps us in lifting objects? Joints make all these movements possible. We cannot imagine our daily life without Joints. In the absence of joints, our body will become stiff, and we will not be able to do any activity. Joints produce flexibility to the skeleton by connecting the bones. All joints have a different way of functioning, and they are involved in other forms of movement.
How many types of synovial joints are there?
There are six types of synovial joints found at different locations in the body . Pivot Joint: This joint permits rotational movement around a single axis. One bone is encircled by a ring formed by the other bone at the joint and a ligament. The bone that pivots may either rotate within the ring or the ring may rotate around the bone.
Which joint is movable?
Synovial joints are freely movable and allow for motion at the location where bones meet. They provide a wide range of motion and flexibility. Other joints provide more stability and less flexibility. Bones at cartilaginous joints connected by cartilage and are slightly movable.
What are structural classifications?
Structural classifications are based on how the bones at joints are connected. Fibrous, synovial, and cartilaginous are structural classifications of joints. Classifications based on joint function consider how movable bones are at joint locations. These classifications include immovable (synarthrosis), slightly movable (amphiarthrosis), ...
What is the capsule of the articular joint?
Articular Capsule: Composed of fibrous connective tissue, this capsule surrounds the joint and connects to adjacent bones. The inner layer of the capsule is lined with a synovial membrane that produces the thick synovial fluid.
What is an immovable joint?
Immovable or fibrous joints are those that do not allow movement (or allow for only very slight movement) at joint locations. Bones at these joints have no joint cavity and are held together structurally by thick fibrous connective tissue, usually collagen. These joints are important for stability and protection.
What are the structures that support bones at synovial joints?
Additionally, bones at synovial joints may be supported by structures outside of the joint such as ligaments, tendons, and bursae (fluid-filled sacs that reduce friction between supporting structures at joints).

Synovial joints are freely movable and provide the greatest degree of mobility. OpenStax College/Wikimedia Commons/CC BY 3.0
How to classify joints?
There are two ways to classify joints: on the basis of their structure or on the basis of their function. The structural classification divides joints into bony, fibrous, cartilaginous, and synovial joints depending on the material composing the joint and the presence or absence of a cavity in the joint.
What are the three types of fibrous joints?
There are three types of fibrous joints: sutures, syndesmoses, and gomphoses. Sutures are found only in the skull and possess short fibers of connective tissue that hold the skull bones tightly in place ( Figure 38.23 ).
What are the two types of cartilaginous joints?
Cartilaginous joints are joints in which the bones are connected by cartilage. There are two types of cartilaginous joints: synchondroses and symphyses. In a synchondrosis, the bones are joined by hyaline cartilage. Synchondroses are found in the epiphyseal plates of growing bones in children. In symphyses, hyaline cartilage covers the end of the bone but the connection between bones occurs through fibrocartilage. Symphyses are found at the joints between vertebrae. Either type of cartilaginous joint allows for very little movement.
What is the space between the bones called?
Synovial joints are the only joints that have a space between the adjoining bones ( Figure 38.25 ). This space is referred to as the synovial (or joint) cavity and is filled with synovial fluid. Synovial fluid lubricates the joint, reducing friction between the bones and allowing for greater movement. The ends of the bones are covered with articular cartilage, a hyaline cartilage, and the entire joint is surrounded by an articular capsule composed of connective tissue that allows movement of the joint while resisting dislocation. Articular capsules may also possess ligaments that hold the bones together. Synovial joints are capable of the greatest movement of the three structural joint types; however, the more mobile a joint, the weaker the joint. Knees, elbows, and shoulders are examples of synovial joints.
How many types of synovial joints are there?
Watch this animation showing the six types of synovial joints.
Why are saddle joints called saddle joints?
Saddle joints are so named because the ends of each bone resemble a saddle, with concave and convex portions that fit together. Saddle joints allow angular movements similar to condyloid joints but with a greater range of motion. An example of a saddle joint is the thumb joint, which can move back and forth and up and down, but more freely than the wrist or fingers ( Figure 38.31 ).
Which joints have a space or cavity?
Figure 38.25 Synovial joints are the only joints that have a space or “synovial cavity” in the joint.
What is a Joint?
In particular, a joint refers to the point where two or more objects connect. In context to the human body or the skeleton system, a joint refers to a point where two bones intersect. In other words, a joint is characterized by the connection that occurs between the bones in the skeletal system. The joint is also referred to as an articulation/ articular surface.
What is the most common type of joint in the human body?
Synovial joints are the most common types of joints in the human body, and they are joints helping us perform movements. These types of joints typically have space between the adjacent bones. This space is known as the synovial cavity, and it consists of synovial fluid.
What is cartilage joint?
Cartilaginous joints are identified by the joints where bones are connected using the cartilage. These joints typically allow movements more than the fibrous joints but less than the synovial joints. In other words, these joints are partially movable. Cartilaginous joints permit a range of movements lying between movements allowed through fibrous and synovial joints.
What is a fibrous joint?
Fibrous joints are the simplest type of joints and have very little to no mobility. This means that joints are present in those body areas where bones have no flexibility or require no motion. In fibrous joints, the adjacent bones are connected using the fibrous connective tissue. Since there is no space left between the bones, most fibrous joints do not permit any movement. In another way, the movements are minor and so are almost negligible. These immovable or fixed joints are interlocked with irregular edges in a distinct style. In particular, fibrous joints are formed mainly to create a structure for the human body's specific part. These joints are usually found in three distinct parts of the body, depending on their types.
What is the second type of fibrous joint?
Syndesmoses: The second type of fibrous joints is termed syndesmoses. Syndesmoses represent joints where bones are interconnected using the band of connective tissue (called interosseous ligaments). This eventually allows very little movement to connective tissue fibers, and the amount of movement mainly depends on the length of individual fibers.
What is a glide joint?
Gliding joints are also called the plane joints and planar joints. Gliding joints are the common type of synovial joints. These joints are found in those parts of the body where the two different bones meet and slip over one another in any direction.
What is the function of synovial joints?
As a result, synovial joints provide a range of movements such as walking, dancing, typing, and many more. Apart from this, the ends of bones are covered with a protected layer of articular cartilage, and an articular capsule further protects the whole joint.

Freely movable joints, also known as diarthrosis joints, are the most common in the body. Different types of freely movable joints allow varying movements in different parts of the body.
What is the joint where two bones meet?
Knee joint cutaway image. Image Credit: leonello/iStock/Getty Images. The junction where two bones meet is a joint, also known as a bony articulation. With more than 200 bones in the human body, there are several different types of joints that give the body both mobility and stability.
What is pivot joint?
Pivot Joints. Pivot joints are specially suited for rotating movements. The articulation between the atlas and axis bones in the neck is a pivot joint, which enables the head to turn from side to side. Pivot joints also join the two bones of the forearm, notes Dr. Monique Laberge in the "Encyclopedia of Nursing and Allied Health.".
What is the only saddle joint in the human body?
Saddle Joints. The carpometacarpal joint at the base of the thumb is the only saddle joint in the human body. The lower bone of the joint resembles a saddle. The upper bone fits into the "saddle.". The saddle joint allows the thumb to move toward the palm, enabling you to grasp objects between your thumb and fingers.
What are the largest joints in the body?
The largest joints of the body, at the hips and the shoulders, are ball-and-socket joints. The end of the upper arm and leg bone is rounded, appearing much like a half ball. This bony ball fits into a cup-like socket. Ball-and-socket joints provide the greatest range of movement of all the freely movable joint types. The upper arms and legs are capable of moving backward, forward, and to the side, as noted by Brigham and Women's Hospital. In addition, a ball-and-socket joint allows for rotation of the long bones, providing the arms and legs with a remarkable range of complex movement.

This bony ball fits into a cup-like socket. Ball-and-socket joints provide the greatest range of movement of all the freely movable joint types.
Which type of joint allows the greatest range of motion?
Many different types of joints exist in the human body, but the kind which allows the greatest range of motion is the ball and socket joint. One end of a bone is rounded and ball-like and fits into a cup-like depression of the other bone. The function of this kind of joint is to connect two bones but to do it in such a way that the bone with a rounded end is able to move in all directions. Let’s do an activity to understand it.

Your table legs are most probably joined by a stopped mortise and tenon joint and the chair legs are often attached with the help of angle mortise. 9. Rabbet Joint. Woodworkers form this joint by forming a recess into the edge of the timber.
What is woodworking joint?
Woodworking joints enable us to create items from multiple timber boards. Without the use of wood joinery techniques, everything we make using wood would end up coming from a single piece. Several woodworking joint styles are available to the woodworker to use, providing several creative options when putting together furniture, flooring, and more.
What is dado joinery?
The dado joinery method is similar to a tongue and groove joint. The only difference is that the dado is cut across the woodgrain whereas a groove is cut in the grain direction which is usually along the length of the board. Moreover, there is no tongue carved on the edges, instead, the groove is cut wider to accept the thickness of the mating piece.
What is the difference between dovetail and box joinery?
On the other hand, box joinery is easy to create and works on most types of wood including plywood. You can easily cut the fingers of the box joint on a table saw with a set of dado blades. 14.
