WebActin is a globular contractile protein that interacts with myosin for muscle contraction. Skeletal muscle also has multiple nuclei present in a single cell. Smooth muscle tissue occurs in the walls of hollow organs such as the intestines, stomach, and urinary bladder, and around passages such as the respiratory tract and blood vessels. WebJun 8, 2024 · acetylcholinesterase: an enzyme that catalyzes the hydrolysis of the neurotransmitter acetylcholine into choline and acetic acid Excitation–Contraction Coupling Excitation–contraction coupling is the physiological process of converting an electrical stimulus to a mechanical response.
WebExplanation: Tendons connect skeletal muscle cells to bones, and they are what allow the body to move voluntarily. They are made up of several myofibrils, which are thick and thin filaments that interact to produce force during muscle contraction. View the full answer Step 2/3 Step 3/3 Final answer Transcribed image text: WebAcetylcholine (ACh) is an important neurotransmitter that plays a role in brain functions, such as memory, and body functions, such as muscle contractions to move your muscles. Low levels of acetylcholine are associated with memory issues and muscle disorders.
WebAt the NMJ, the axon terminal releases a chemical messenger, or neurotransmitter, called acetylcholine (ACh). The ACh molecules diffuse across a minute space called the synaptic cleft and bind to ACh receptors located within the motor end-plate of the sarcolemma on the other side of the synapse.
