The series of events prompting muscle contraction is started some place in the central nervous system‚ either as willful action from the brain or as reflex action from the spinal cord. Beginning with depolarization at the neuromuscular junction‚ the depolarizing impulse discharges acetylcholine from the nerve ending. Which then diffuses over the neuromuscular junction (a chemical synapse formed by the contact between a motor neuron and a muscle fiber). At the motor end plate‚ the acetylcholine joins

to the cell‚ which causes new energy for the cell. That process is called autophagy. Levine’s research shows that increased autophagy may be the reason as to why exercise can protect against type two diabetes and other metabolic disorders (Kresge 2). During this process‚ a double membrane forms around the cellular garbage then lysosome‚ an organelle‚ fuses with the membrane and its enzymes rush in to break up the unwanted stuff‚ making raw materials for producing new proteins or energy for the

MANY PROCESSES MUST TAKE place within the skeletal muscle fibres in order for muscle contraction to occur. The cross bridge cycle‚ process by which the muscle length is shortened as myosin heads‚ extending from the myosin filaments‚ interact cyclically in a rowing motion with the actin filament (Rayment et al. 1993)‚ is one of the crucial mechanical events required. The mechanism is initiated when an ATP molecule is bound to a myosin head. An enzyme within the head. known as ATPase‚ hydrolyzes the

Skeletal System Study Guide – Use the lecture folder to help you answer these questions. The more detail you add‚ the better prepared for the test you will be. 1. What are the functions of the skeleton? Support & Protection‚ Body Movement‚ Hemopoiesis‚ Mineral Storage 2. What is the difference between osteoclasts and osteoblasts? Osteoblast are cells that generate bones‚ osteoclasts are cells that destroy bone. 3. How many bones do we have in our body? 206 4. What do bones need in order
