What are the intercarpal joints?
The intercarpal joints are the synovial plane joints that connect the carpal bones. They gather three sets of joints; Joints of the proximal carpal row, that connect the adjacent surfaces of the scaphoid, lunate and triquetrum bones.
What are the different types of synovial joints?
List different types of synovial joints. Synovial joints are not all identical. There are six further subdivisions of synovial joints: gliding, hinge, pivot, ellipsoidal, saddle, and ball-and-socket joints. Gliding joints have nonaxial movement that involves linear gliding and flat, articular surfaces.
Which synovial joint is the most movable?
Movement in saddle joint is somewhat similar to the ellipsoid joint, in addition, there is also rotation around a third axis. The examples are carpometacarpal joint thermochemical joints and clan calcaneocuboid joint. The last on the list of types of synovial joints is the most movable of all the types.
What is the function of the midcarpal?
Midcarpal joint, by which the carpal rows articulate with each other. The joints of the proximal and distal carpal rows are supported and fixed by many ligaments, so there is minimal movement within them. Their function is to coordinate the movements of the wrist (radiocarpal) and midcarpal joints.

Why are intercarpal joints called the gliding joints?
The intercarpal joints are an example of __________ joints. Explanation: Gliding joints, also called plane joints, have flat articular surfaces that allow movement in all different directions. (There are eight carpal bones in the wrist: scaphoid, lunate, triquetrum, pisiform, trapezium, trapezoid, capitate, hamate.)
What type of synovial joint is between radius and Carpals?
The radiocarpal joint is a synovial joint formed between the radius, its articular disc and three proximal carpal bones; the scaphoid, lunate and triquetral bones.
What is Intercarpal joint?
The intercarpal joints are the synovial plane joints that connect the carpal bones. They gather three sets of joints; Joints of the proximal carpal row, that connect the adjacent surfaces of the scaphoid, lunate and triquetrum bones.
What is the example of hinge joint?
[3][4] The hinge joints of the body include the elbow, knee, interphalangeal (IP) joints of the hand and foot and the tibiotalar joint of the ankle.
What type of synovial joint is the wrist?
condyloid synovial jointThe wrist joint also referred to as the radiocarpal joint is a condyloid synovial joint of the distal upper limb that connects and serves as a transition point between the forearm and hand. A condyloid joint is a modified ball and socket joint that allows for flexion, extension, abduction, and adduction movements.
Is wrist a pivot joint?
The joint of the wrist that allows the palm of the hand to be turned up and down is also a pivot joint.
Where is pivot joint located?
The pivot joint located near the elbow, holds the two forearm bones, radius and ulna, together. The two bones, radius and ulna, are also connected to each other near the wrist by another pivot joint.
What type of joint is the saddle joint?
What are Saddle Joints? A saddle joint is a type of biaxial and movable joint that allows movements on two planes–flexion or extension and abduction or adduction. This joint is mainly formed between the bones, whose articulating surfaces have both concave and convex regions.

Carpal Joint - an overview | ScienceDirect Topics
S. Hudson, in Feline Orthopedic Surgery and Musculoskeletal Disease, 2009 Elbow. The carpal joint must be flexed and extended, respectively, to flex and extend the elbow. Begin with the carpal joint supported by one hand and the other behind the elbow. Gently push the elbow into extension end feel. The carpal joint will extend at the same time.
Motion
The intercarpal joints are synovial ellipsoid or spheroidal joints. The term intercarpal joints refers to the joints between the proximal row of carpal bones, the joints between the distal row of carpal bones and the complex midcarpal joint between the two rows.
Stability
An extensive fibrous capsule (especially at the level of the midcarpal joint) plays an important role in stabilizing the joints.

Why are synovial joints called synovial joints?
They are called synovial joint because is filled with synovial fluid which acts as lubricants. It is also interesting to know that there are 6 types of synovial joints in our body. But our body also has numerous immovable joints which do not allow any movement. In this article, we are concerned about the movable joints / synovial joints, ...
How many types of synovial joints are there?
What are the types of synovial joints? There are a total of 7 types of synovial joints in the human body. These joints allow movement which is why it is also known as movable joints. Actually, the articulating surface of this type of joint is filled with a special lubricating fluid known as synovial fluid. This fluid provides lubrication ...
What are some examples of plane joints?
So the plane joint permits gliding movement. The examples of plane joint are intercarpal joints, intertarsal joints, joints between articular processes of vertebrae.
What are the two types of joints?
Types of joints in human body. Whenever two or more bones meet they form a joint. The human body has broadly two types of joint, one is immovable joint and another is movable joint.
Why is cartilage smooth?
Smooth cartilage allows friction-less movement and this smoothness is further enhanced by body lubricants. Our movable joints are also lubricated and filled with fluid known as synovial fluid and this is why we call this joint as synovial Joint.
Which synovial joint is the most movable?
The last on the list of types of synovial joints is the most movable of all the types. As the name suggests the ball and socket joint consists of a ball that fits into the socket a cup-shaped socket. The spherical ball fits into the cup-shaped socket and that’s why it allows movement in almost all direction. It gives great freedom of movement.
What is the purpose of immovable joints?
However, there are other joints whose purpose is to maintain the structure of the body parts by not allowing movement, they are fixed and do not take part in any kind of movement. These are immovable joints.
What are the intercarpal joints?
The intercarpal joints are the synovial plane joints that connect the carpal bones. They gather three sets of joints; Joints of the proximal carpal row, that connect the adjacent surfaces of the scaphoid, lunate and triquetrum bones.
What is the function of the midcarpal joint?
Their function is to coordinate the movements of the wrist (radiocarpal) and midcarpal joints.
What are the interosseous ligaments of the proximal carpal row?
The interosseous ligaments of the proximal carpal row are named according to the bones that they connect; namely the scapholunate and lunotriquetral ligaments. These structures span between the adjacent sides of the relevant carpal bones, thus separating the joint spaces of the midcarpal and radiocarpal joints.
What is the pisiform joint?
The pisiform joint, an articulation between the pisiform and triquetrum, is described as a separate joint but it belongs to the proximal carpal joints. Joints of the distal carpal row, via which the adjacent surfaces of the trapezium, trapezoid, capitate, and hamate bones articulate.
What are the ligaments that support the carpal bones?
The joints of the carpal bones are supported by an array of ligaments, namely the interosseous intercarpal ligaments, dorsal intercarpal ligaments, and palmar intercarpal ligaments. It’s worth noting that these ligaments are variably described in the literature, which has led to a degree of confusion in regards to their anatomy.
Which bones are connected to the proximal carpal row?
The joints of the proximal carpal row connect the relatively flat/planar adjacent surfaces of the scaphoid and lunate, and triquetral bones, forming the scapholunate and lunotriquetral joints. The pisiform bone, which lies within the tendon of the flexor carpi ulnaris muscle, articulates with the palmar surface of triquetrum bone, forming the pisiform joint. The pisiform bone is also connected to the hook of hamate bone and fifth metacarpal bones via pisohamate and pisometacarpal ligaments, respectively.
Where is the dorsal intercarpal ligament located?
The dorsal intercarpal ligament is a horizontal strap that arises from the dorsal tubercle of the triquetrum bone to the dorsal groove of the scaphoid bone, and may pass additional fibres to the trapezoid and capitate bones. It forms the floor of the fourth and fifth dorsal (extensor) compartments of the wrist.
