Document Summary
Uses calmodulin, has tropomyosin but it does not block active sites on actin. Un-phosphorylated myosin head do not detach from actin immediately remains attached without consuming atp, more ca channels (ca slower and stay open longer) 1 nerve innervates multiple fibers and communicate via gap junctions. Maintains significant tension over broader range of muscle length, less energy. Gaba binds to receptors that are chlorine channels. Ach binds to nicotinic receptor on ligand gated ion channels. On nmj brain neurons, post ganglion, neurons in ans. Voltage gated channels on the trigger zone and axon. Self propagating, has effects a great distance from point of origin. May be a positive(depolarizing) or negative(hyperpolarizing) voltage change. Local, has effects only a short distance from point of origin. Protects blood capillaries through out the brain tissue. Second largest brain region, coordinates movement and locomotor ability, also has sensory linguistic, emotional and other nonmotor.
