What is a skeleton overview?
Human skeleton At the simplest level, the skeleton is the framework that provides structure to the rest of the body and facilitates movement. The skeletal system includes over 200 bones, cartilage, and ligaments.
What are the 5 parts of the skeleton?
These are (1) the axial, comprising the vertebral column—the spine—and much of the skull, and (2) the appendicular, to which the pelvic (hip) and pectoral (shoulder) girdles and the bones and cartilages of the limbs belong.
What are the 5 main functions of the skeletal system?
The skeletal system works as a support structure for your body. It gives the body its shape, allows movement, makes blood cells, provides protection for organs and stores minerals. The skeletal system is also called the musculoskeletal system.

What are the main parts of human skeleton?
Axial and Appendicular Skeletons The skeleton is traditionally divided into two major parts: the axial skeleton and the appendicular skeleton, both of which are pictured in Figure 14.2. 3. The axial skeleton forms the axis of the body. It includes the skull, vertebral column (spine), and rib cage.
What is the main part of skeleton?
The adult human skeleton usually consists of 206 named bones. These bones can be grouped in two divisions: axial skeleton and appendicular skeleton. The 80 bones of the axial skeleton form the vertical axis of the body. They include the bones of the head, vertebral column, ribs and breastbone or sternum.
What are the 6 functions of the skeleton?
Why is our skeleton important?
Bones work with muscles and joints to hold our body together and support freedom of movement. This is called the musculoskeletal system. The skeleton supports and shapes the body and protects delicate internal organs such as the brain, heart and lungs. Bones contain most of our body’s calcium supply.
What is a skeleton made of?
The adult human skeleton is made up of 206 bones. These include the bones of the skull, spine (vertebrae), ribs, arms and legs. Bones are made of connective tissue reinforced with calcium and specialised bone cells. Most bones also contain bone marrow, where blood cells are made.

Which of these is a function of the skeleton?
The major functions of the skeletal system are body support, facilitation of movement, protection of internal organs, storage of minerals and fat, and blood cell formation.
How does the skeleton protect the body?
The skeleton supports the body against the pull of gravity. The large bones of the lower limbs support the trunk when standing. The skeleton also protects the soft body parts. The fused bones of the cranium surround the brain to make it less vulnerable to injury.
