Golgi Tendon Organ
Regulates changes in muscle TENSION
Muscle Spindles
Regulate changes in muscle LENGTH
Fascia
Outer layer of connective tissue surrounding the muscle
Type I Muscle Fibers
Slow twitch - slow to fatigue
Type II Muscle Fibers
Fast twitch - Quick to fatigue
Local Stabilization System
Attach to vertebrae - Consists of the transverse abdominis, internal oblique, pelvic floor, and diaphragm
Global Stabilization System
Attach to the pelvis and spine - papas major, external oblique, and recurs abdominous
Movement System
Attached spine and pelvis to extremities - latissimus dorsi, hip flexor, hamstring, quadriceps
Athrokinetics
Joint motion
Hinge Joints
Elbows, Ankles - Sagital plane motion
Ball In Socket
Shoulder, Hip - movement in all three planes
Cardiac Muscle
Short muscles
Atria
Receives blood from veins
Right Atria
Gathers deoxygenated blood to the heart
Left Atria
Gathers OXYGENATED blood from the lungs
Right Ventricle
Pump deoxygenated to the lungs
Left Ventricle
Pump OXYGENATED blood to the body
Arteries
Carry blood from the heart to body
Veins
Carry blood back to the heart
Resting Oxygen Consumption
