Nanette Morris, RN, BA, NBCT Muscular System

Nanette Morris, RN, BA, NBCT THE MUSCULAR SYSTEM THE COMPOSITION  MUSCLES  TENDONS & FASCIA

Nanette Morris, RN, BA, NBCT THE MUSCULAR SYSTEM PROPERTIES  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 SYSTEM TYPES  INVOLUNTARY: –CARDIAC:the heart –VISCERAL OR SMOOTH: internal organs  VOLUNTARY: –SKELETAL:the bones

Nanette Morris, RN, BA, NBCT THE MUSCULAR SYSTEM THE MOVEMENTS  ADDUCTION: towards  ABDUCTION: away from  FLEXION: decrease the angle  EXTENSION: increase the angle  ROTATION: circular

Nanette Morris, RN, BA, NBCT THE MUSCULAR SYSTEM THE 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 SYSTEM THE DISEASES  Muscular Dystrophy: chronic & progressive muscle atrophy  Myasthenia Gravis: interrupted nerve impulses  Spasms: involuntary cramping  Strain: overstretching

Nanette Morris, RN, BA, NBCT THE CIRCULATORY SYSTEM THE COMPOSITION  THE HEART  THE BLOOD VESSELS  THE BLOOD

Nanette Morris, RN, BA, NBCT THE CIRCULATORY SYSTEM THE FUNCTION  TRANSPORTS O 2 & NUTRIENTS TO THE BODY CELLS  TRANSPORTS CO 2 & WASTES AWAY FROM BODY CELLS

Nanette Morris, RN, BA, NBCT The Circulatory System  Diseases: Anemia: Low RBC count Arteriosclerosis: hardening of arterial walls Hypertension: high blood pressure Leukemia: malignant disease of bone marrow or lymph tissue
