Musculoskeletal system stubs

Musculoskeletal system refers to the complex system in the body that includes the bones, joints, ligaments, tendons, muscles, and nerves. It is responsible for supporting the body, allowing movement, and protecting vital organs.

Structure

The musculoskeletal system is made up of two main components: the skeletal system and the muscular system. The skeletal system provides the rigid framework of the body, while the muscular system allows for movement by contracting and relaxing muscles.

Skeletal System

The skeletal system is composed of 206 bones in the adult human body. These bones are categorized into two groups: the axial skeleton, which includes the skull, vertebral column, and rib cage; and the appendicular skeleton, which includes the limbs and pelvis.

Muscular System

The muscular system is composed of over 600 muscles, which are attached to bones by tendons. These muscles can be categorized into three types: skeletal, cardiac, and smooth muscles. Skeletal muscles are responsible for voluntary movements, while cardiac muscles and smooth muscles control involuntary movements such as the heartbeat and digestion.

Function

The primary functions of the musculoskeletal system are to provide support, allow movement, and protect internal organs. The skeletal system provides a rigid framework that supports the body and maintains its shape. The muscles provide the force to move the bones. The system also protects the internal organs from injury.

Diseases and Disorders

There are many diseases and disorders that can affect the musculoskeletal system, including arthritis, osteoporosis, and muscular dystrophy. These conditions can cause pain, limit movement, and lead to disability.

Treatment and Management

Treatment for musculoskeletal disorders often involves a combination of medication, physical therapy, and in some cases, surgery. Management of these conditions often involves lifestyle changes such as exercise and diet modification.
