Answer Details
The passage of nerve impulse across a synapse is facilitated by the secretion of acetylcholine. Acetylcholine is a neurotransmitter, a chemical messenger that helps to transmit signals across nerve cells or synapses. When an electrical signal, or nerve impulse, reaches the end of a nerve cell, it triggers the release of acetylcholine from vesicles into the synapse. The acetylcholine then binds to receptors on the adjacent nerve cell, causing an electrical signal to be generated in the receiving cell. This process allows nerve impulses to be transmitted from one cell to the next, enabling communication between different parts of the nervous system.
