What is the function of the human skeleton?
The human skeleton is the framework of the human body. It supports the softer tissues, provides points of attachment for most skeletal muscles and protects many vital organs. It also maintains the body’s’ shape.
How do the muscular and skeletal systems work together?
The muscular and skeletal systems work together as the musculoskeletal system, which enables body movement and stability. When muscles contract, they pull on bones of the skeleton to produce movement or hold the bones in a stable position. The shape of the bones and how they fit together at the joints allows for different types of movement.
What is an overview of the skeletal system?
Skeletal System Overview. Medically reviewed by William Morrison, MD on August 30, 2018 — Written by Jill Seladi-Schulman, PhD. The human skeletal system consists of all of the bones, cartilage, tendons, and ligaments in the body. Altogether, the skeleton makes up about 20 percent of a person’s body weight.
How does the skeleton protect internal organs from damage?
4. Protection. The skeleton protects the internal organs from damage by surrounding them with bone. Bone is living tissue that is hard and strong, yet slightly flexible to resist breaking. The strength of bone comes from its mineral content, which is primarily calcium and phosphorus.
How does the skeleton support the body?
...n your own words, describe how the human skeleton supports the human body. The human skeleton is the framework of the human body. It supports the softer tissues, provides points of attachment for most skeletal muscles and protects many vital organs. It also maintains the body’s’ shape. The skeleton is made up of bones that can be categorised according to one of five functions that they perform; • Shape and support; The skeleton provides the shape and support that gives the body its shape. As well as providing gravitational support, it supports the softer tissues and provides points of attachments for most skeletal muscle. • Movement; Some bones provide leverage for movement. Most of the bones are connected to other bones at flexible joints, which allow the skeletal framework a high degree of flexibility and movement. The bones are attached to tendons of the skeletal muscle and the ligaments of the joints. They then act as levers and pulleys to aid the contraction of the skeletal muscles into movement. • Protection; The skeleton provides protection for the body’s vital organs, reducing risk of injury to them. Blood production; Red blood cells and some white blood cells are manufactured by the bone marrow which is found in the cavities of some of the larger bones. Haematopoiesis is the formation of blood cells. This normally takes place in the red marrow of the bones. Each bone consists of a compact outer shell and a spongy centre. The centre contains the bone marrow......

What is the outer shell of a bone?
Each bone consists of a compact outer shell and a spongy centre. The centre contains the bone marrow which produces blood cells. In infants, red marrow is found inside the bone. As you age, the red marrow is mainly replaced by yellow marrow for fat storage.
How many bones are in the skeletal system?
The skeletal system consists of 206 bones, 80 of which are found in the axial division, and 126 of which make up the appendicular division.
What is the skeletal system?
Bone is a living tissue and is functionally dynamic. It provides a supportive framework for vital body organs, serves as areas for muscle attachment, articulates at joints for stability and movement, and assists in respiratory movements. In addition, it provides areas of storage for substances such as calcium and lipids, and blood cell formation occurs within the cavities containing bone marrow. The skeletal system consists of 206 bones, 80 of which are found in the axial division, and 126 of which make up the appendicular division. Many of the bones of the body, especially those of the appendicular skeleton, provide a system of levers used in movement, and are utilized in numerous ways to control the environment that surrounds you every second of your life. Few people relate the importance of movement as one of the factors necessary for maintaining life, but the body doesn't survive very long without the ability to produce movements. The study and review for this chapter includes microscopic and macroscopic features of bone, bone development and growth, location and identification of bones, joint classification, and the structure of representa......
What is the function of bones in the body?
They then act as levers and pulleys to aid the contraction of the skeletal muscles into movement. • Protection; The skeleton provides protection for the body’s vital organs , reducing risk of injury to them.
What is the function of the skeleton?

As well as providing gravitational support, it supports the softer tissues and provides points of attachments for most skeletal muscle.
Why do children's skeletons have more bones?
Children’s skeletons actually contain more bones because some of them, including those of the skull, fuse together as they grow up. There are also some differences in the male and female skeleton. The male skeleton is usually longer and has a high bone mass.
What are the two parts of the skeletal system?
Regardless of age or sex, the skeletal system can be broken down into two parts, known as the axial skeleton and the appendicular skeleton.
How many bones are in the axial skeleton?
The adult axial skeleton consists of 80 bones. It’s made up of the bones that form the vertical axis of the body, such as the bones of the head, neck, chest, and spine.
What is the term for a disease that affects bone strength?
Metabolic bone diseases. Metabolic bone diseases refer to a group of conditions that affect bone strength or integrity. They can be due to things such as a deficiency in vitamin D, loss of bone mass, and use of certain medications, such as steroids or chemotherapy.
How many cranial bones are there in the human body?
Cranial bones. The eight cranial bones form the bulk of your skull. They help to protect your brain.
What is the bone of the upper arm?
Humerus. The humerus is the long bone of the upper arm.
How many bones are in each leg?
Each leg is composed of 30 bones, known as the:
How do you see how bones support movement?
Simply by looking at a person, you can see how the bones support, facilitate movement, and protect the human body. Just as the steel beams of a building provide a scaffold to support its weight, the bones and cartilage of your skeletal system compose the scaffold that supports the rest of your body.
Which bones protect the brain?
For example, your ribs protect your lungs and heart, the bones of your vertebral column (spine) protect your spinal cord, and the bones of your cranium (skull) protect your brain ( [link] ). The cranium completely surrounds and protects the brain from non-traumatic injury.
What is the softer connective tissue that fills the interior of most bones called?
The softer connective tissue that fills the interior of most bone is referred to as bone marrow ( [link] ). There are two types of bone marrow: yellow marrow and red marrow. Yellow marrow contains adipose tissue; the triglycerides stored in the adipocytes of the tissue can serve as a source of energy.
What is the body system composed of bones and cartilage?
The skeletal system is the body system composed of bones and cartilage and performs the following critical functions for the human body: supports the body.
What does orthopedics mean?
While the origin of the word “orthopedics” (ortho- = “straight”; paed- = “child”), literally means “straightening of the child,” orthopedists can have patients who range from pediatric to geriatric. In recent years, orthopedists have even performed prenatal surgery to correct spina bifida, a congenital defect in which the neural canal in the spine of the fetus fails to close completely during embryologic development.
What is bone in anatomy?
Learning Objectives. Bone, or osseous tissue, is a hard, dense connective tissue that forms most of the adult skeleton, the support structure of the body. In the areas of the skeleton where bones move (for example, the ribcage and joints), cartilage, a semi-rigid form of connective tissue, provides flexibility and smooth surfaces for movement. ...
What is the career of an orthopedist?
Career Connection. Orthopedist. An orthopedist is a doctor who specializes in diagnosing and treating disorders and injuries related to the musculoskeletal system. Some orthopedic problems can be treated with medications, exercises, braces, and other devices, but others may be best treated with surgery ( [link] ).
What are the functions of the skeletal system?
Support – the skeleton keeps the body upright and provides a framework for muscle and tissue attachment. Posture – the skeleton gives the correct shape to our body. Protection – the bones of the skeleton protect the internal organs and reduce the risk of injury on impact.
Which bones protect the internal organs?
Protection – the bones of the skeleton protect the internal organs and reduce the risk of injury on impact. For example, the cranium protects the brain, the ribs offer protection to the heart and lungs, the vertebrae protect the spinal cord and the pelvis offers protection to the sensitive reproductive organs.
