Skeletal System

Explore the skeletal system in detail, from its crucial functions like support and protection to common bone injuries such as fractures and dislocations, as well as bone disorders like arthritis and osteomyelitis. Learn about different parts of bones, types of fractures, and spinal conditions like kyphosis and scoliosis.
