FUNCTION MOVEMENT OF THE BODY PROVIDES MUSCLE TONE GENERATES HEARTBEAT DISTRIBUTES HEAT PERISTALSIS

STRUCTURE

NEUROMUSCULAR JUNCTION

ACTIN & MYOSIN

MUSCLE CONTRACTION

IN ORDER FOR THE MUSCLE CONTRACTION TO OCCUR, THE BODY USES : GLYCOLYSIS CELLULAR RESPIRATION ADP + CREATINE PHOSPHATE ATP

OXYGEN IN CONTRACTION

OXYGEN IN FATIGUE & CRAMPING NEED FOR OXYGEN ANAEROBIC RESPIRATION EXERCISE

MUSCLE RESPONSES SUMMATION + RECRUITMENT = MUSCLE TONE SUMMATION SUSTAINED CONTRACTION RECRUITMENT SUMMATION + RECRUITMENT = MUSCLE TONE
