Front 17

PELVIS

Back 17

the basin – shaped bony structure that supports the spine and is the point of proximal attachment for the lower extremities. (commonly referred to as the hip, although the hip is actually the joint where the femur and pelvis join). Contains bones that are fused together, the pelvis is joined posteriorly to the sacral spine.

Muscles

Back 49

tissue that contract to allow movement of a body part; interact with the skeletal system. There are three types of muscle; voluntary muscle, involuntary and cardiac.

Front 50

Voluntary Muscle

Back 50

(skeletal muscle); is under conscious control of the brain via the nervous system. Attached to bones, the voluntary muscles form the major muscle mass of the body and are responsible for movement.

Front 51

Involuntary Muscle

Back 51

(smooth muscle) muscle that responds automatically to brain signals but cannot be consciously controlled. Found in the gastrointestinal system, lungs, blood vessels, and urinary system; controls the flow of materials through these structures. They will respond to stimuli such as stretching, heat and cold.

Front 52

Cardiac Muscle

Back 52

specialized involuntary muscle found only in the heart, and is extremely sensitive to decreased oxygen supply and can tolerate interruption of blood supply for only very short periods. The heart also has a property called automaticity.

Front 53

Automaticity

Back 53

the ability of the heart to generate and conduct electrical impulses on its own
