Document Summary

Movements are linked to the range of joint action. Joints (arthroses) are connections between bones that may or may not permit movement. Two bones may be in direct contact with each other or separated by: Joints can be classified based on their range of motion (function) Syndesmosis (ligaments that connect two bones but limit their motion) Between the radius and ulna, between the tibia and fibula. Symphysis (bones are separated by a wedge or pad of cartilage) Between the pubic bones of the two coxal bones. Typically found at the ends of long bones. Examples of diarthroses joints: shoulder joint, elbow joint, hip joint, knee joint. Oval articular surface on one bone articulates with a depression. Radius/capitulum radius/carpals phalanges/metacarpals on another bone. The skeletal muscle of the body can be subdivided into: Muscles that position the head and vertebral column. Muscles that stabilize or move the appendicular skeleton.
