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

THE MUSCULAR SYSTEMTYPES

INVOLUNTARY:– CARDIAC: the heart– VISCERAL OR SMOOTH: internal organs

VOLUNTARY:– SKELETAL: the bones

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

THE MUSCULAR SYSTEMTHE DISEASES

Muscular Dystrophy: chronic & progressive muscle atrophy

Myasthenia Gravis: interrupted nerve impulses

Spasms: involuntary cramping Strain: overstretching
