Skeletal System

The human skeletal system is the collection of bones, joints, and other connective tissues that support and give shape to the body.

It includes both the axial skeleton, which comprises the bones of the head and trunk and the appendicular skeleton, which consists of the bones of the limbs.

The adult human skeleton typically contains 206 bones, although this number can vary depending on the individual.

The skeletal system provides support and protection for the body’s organs, helps to maintain posture, and allows for movement.

The bones of the skeleton are connected to each other at joints, which allows for flexibility and movement. The skeletal system also contains the muscles, which are attached to the bones and enable the body to move.

The human skeleton is constantly changing throughout life. During childhood and adolescence, the bones grow in length and size as a result of a process called ossification.

As we age, the bones begin to lose density and strength, which can lead to conditions such as osteoporosis.
