THE MUSCULAR SYSTEMPROPERTIES
Excitability: the ability to respond to a stimulus
Contractibility: the ability to contract Extensibility: the ability to stretch Elasticity: the ability to return to original
shape
Nanette Morris, RN, BA, NBCT
THE MUSCULAR SYSTEMTYPES
INVOLUNTARY:– CARDIAC: the heart– VISCERAL OR SMOOTH: internal organs
VOLUNTARY:– SKELETAL: the bones
Nanette Morris, RN, BA, NBCT
THE MUSCULAR SYSTEMTHE MOVEMENTS
ADDUCTION: towards ABDUCTION: away from FLEXION: decrease the angle EXTENSION: increase the angle ROTATION: circular
Nanette Morris, RN, BA, NBCT
THE MUSCULAR SYSTEMTHE TONE
MUSCLE TONE: normal, steady partial contraction
ATROPHY (shrinkage) CONTRACTURES (severe tightening of
flexors) occur from lack of use
Nanette Morris, RN, BA, NBCT
THE MUSCULAR SYSTEMTHE DISEASES
Muscular Dystrophy: chronic & progressive muscle atrophy
Myasthenia Gravis: interrupted nerve impulses
Spasms: involuntary cramping Strain: overstretching
