Your Answer: Acetychlorine binds with receptors on the muscle cell membrane, opening sodium channels. Sodium rushes in, creating an action potential, which reaches the sarcolemma and then the sarcoplasmic reticulum. Once the action potential reaches the sacroplasmic recticulum, calcium ions are released. The influx of calcium triggers the cross-bridge formations to and muscle contraction. Acetylcholine (a special chemical called a neurotransmitter) is released from a motor nerve at the neuromuscular junction (or NMJ). Acetylcholine binds to receptors on the muscle fiber that cause sodium channels to open. Sodium ions rush inside the cell, triggering an action potential which eventually reaches the sarcoplasmic reticulum. Calcium ions are released from the sarcoplasmic reticulum of the muscle cell, causing a muscle contraction to occur. Quiz Score: 84.5 out of 100
