4 functions: | *movement *structures/postures *heal productions *protection |
movement: | all body movement depends of muscle action |
structure/posture: | muscle accounts for @ least 50% body weight |
heal productins: | wounds close after time, fascia re-closes an open area. |
Protection: | limits movement to avoid injury:golgi tendon organ/muscle spindle |
1.muscle: | skeletal (voluntary) A. attached to bone B. slow twitch/fast twitch |
2.muscle: | cardiac (involuntary) A. heart b. controls itself & its rhythm: mechanical/electrical C. designed for endurance |
3.muscle | smooth (involuntary) A. found in visera, blood vessels, intestines B. designed to maintain long contractions. |

retinaculum: | bandage like connective tissue, holds structures in place. |
muscletone: | partial state of muscle |
contraction: | posture |
flacid: | lack of tone |
hypertonicity: | too much tone |
agonist: | prime mover |
synorgist: | assists the prime mover |
antagonist: | opposes prime mover |
fixator: | stabilize proximal aspects so that dostal can move to it's max |

lever system: | *class 1 (FAR) *class 2 (FRA): wheel barrel; power speed *CLASS 3 (AFR): bicep curl |
suport: | holds bones in place; every bone is connected to another bone by ligaments (except hyoid) |
