Has 126 bones

axial skeleton

Has 80 bones along central axis

long bones location

Ossification

The process of bone development

axial and appendicular

The two divisions of the skeleton are:

Ball and socket

This joint offers the greatest range of motion

ostearthritis

This joint pathology is characterized by the inflammation of the joint capsule and joint damage is progressive leading to loss of cartilage

multiaxial

This joint provides movement in all three cardinal planes

Uniaxial

This joint provides movement in one axis

Baker cyst

rheumatoid arthritis

This pathology is chronic inflammatory systemic arthritis that destroys synovial membranes

Osteoporosis

This pathology is the loss of normal bone density and increases susceptibility of fractures
