Question:
During muscle contraction, a neural signal, released by central nervous system, when reaches the neuromuscular junction, it releases a neurotransmitter (Acetylcholine) which generates an action potential in the sarcolemma. This action potential along the length spreads through the muscle fibre and causes the release of calcium ions into the sarcoplasm.
(a) Describe the significance of Ca2+ ions in the contraction of muscles.
(b) Which neurotransmitter is responsible for contraction of muscle?
