Skeletal System



The skeletal system, also known as the musculoskeletal system, is the framework of bones, cartilage,ligaments, and tendons that provide structure, support, and protection to the body. It is essential for movement, stability, and protection of internal organs.

The human skeletal system consists of 206 bones, which are connected by joints. Bones are made up of living tissue and are constantly being remodeled and repaired throughout a person's life. Bones also serve as a storage site for important minerals, such as calcium and phosphorus.

Cartilage is a type of connective tissue that is found throughout the body, including in the joints. It provides a smooth surface for bones to glide over and acts as a shock absorber, reducing friction and preventing damage to the bones.

Ligaments are strong bands of connective tissue that connect bones to other bones, providing stability and limiting the range of motion of the joints. Tendons are another type of connective tissue that attach muscles to bones, allowing movement to occur.

The skeletal system is divided into two main parts: the axial skeleton and the appendicular skeleton. The axial skeleton includes the skull, vertebral column, and rib cage, which protect the brain, spinal cord, and vital organs. The appendicular skeleton includes the bones of the arms, legs, pelvis, and shoulder girdle, which are involved in movement and support.

Overall, the skeletal system is a complex and important system that provides support, protection, and mobility to the human body. Proper nutrition and exercise are essential for maintaining strong and healthy bones and joints throughout life.
