The Skeletal System

Bones in this system...
The adult human skeletal system consists of 206 bones, as well as many tendons, ligaments, and cartilage that connects them. However, these are the general bones:
Skull, Clavicle, Scapula, Humerus, Ribs, Vertebrae, Radius, Ulna, Coxal Bone, Sacrum, Coccyx, Carpal Bones, Metacarpal Bones, Phalanges, Femur, Patella, Tibia, Fibula, Tarsal Bones, Metatarsal Bones, Phalanges.
The skeletal system supports and stores energy and minerals for other body systems!
Functions...
Joints, Ligaments, and Cartilage...
Angular Motion
Rotation
Special Movements
Inversion is a twisting motion of the foot that turns the sole inward. The opposite is called eversion. Elevation and depression occur when a structure moves in a superior or inferior direction. Opposition is the movement of the thumb toward the palm or fingertips that lets you grasp an object.
Bones can be classified according to shape and structure...
Diseases/ Disorders...
Many of the disorders and diseases of this system are common and well-known today. Arthritis is a disease that affects synovial joints. It always involves damage to cartilages. The effects of arthritis are usually classified as inflammatory. You can also get carpal tunnel syndrome. This is inflammation of the tissues of the wrist that causes compression of nearby the wrists that causes compression of tendons and nerves. Symptoms are pain and a loss of wrist mobility. Spina bifida is a condition resulting from the failure of the vertebral laminae to fuse together during development. This often occurs with abnormalities of the spinal cord and brain. Luxation, a dislocation, is a condition in which the articulated surfaces are forced out of position. As a result of this, scoliosis can occur. This is an abnormal lateral curvature of the spine.
