MUSCLE PROPERTIES Irritability - stimulation Conductivity - wave Contractility - tension Distensibility - stretching Elasticity - recoil ability

QUALITIES OF MUSCLES Flexibility - ROM Strength - tension Power - Fv Endurance - repeated/sustained

Skeletal Muscle Anatomy Attachment Origin Insertion

FIBER ARRANGEMENTS Fusiform - longitudinal Pennate - oblique angle

LAN Location Angle Number

ACTIVE INSUFFICIENCY Biarticulate Muscle Contraction Limitation Figure 2.3 page 57 - Left Hamstrings

PASSIVE INSUFFICIENCY Biarticulate Muscle Stretching Limitation Figure 2.3 page 57 - Right Hamstrings

MUSCLE & ARTICULATION Uniarticulate Biarticulate e.g knee/hip joints (hams,quads) Multiarticulate e.g. elbow/radioulnar/wrist/hand joints (flexor digitorum profundus)

RECIPROCAL INNERVATION Agonist Antagonist

MUSCULAR TENSION TYPES Static - isometric Dynamic Concentric Eccentric

SYNERGY Working Together - two agonists work together to move segment True - agonist moves, antagonist stabilizes Helping - both agonist & antagonist work together to move segment

Question 15 - page 60 Articulation/joint Motion name Motive Force Resistive Force Contraction Type Stabilized Area

Figure 2.5 C - page 61 Articulation - knee Motion - extension & flexion Motive F - muscle & g Resistive F - g & muscle Contraction - concentric & eccentric Stabilized - trunk & thigh
