Muscles
Briefly goes through the structure of a muscle fiber and their functions. Neurons that carry signals to skeletal muscles, acetylcholine and nicotinic receptors. Excitation-coupling-contraction-relaxation process, motor units and motor unit recruitments. Twitch summation and tetanus. Concentric, eccentric, and isometric actions, muscle length to tension relationships. Creatine Phosphate system, anaerobic glycolysis, and oxidative metabolism. Atrophy, increased oxidative capacity, fiber type transition, differences in smooth and skeletal muscles. Single Unit smooth muscle functions
