Question

place the following events in synaptic transmission at a cholinergic synapse in order: a - a postsynaptic potential is produced; b - voltage - gated calcium channels open and calcium enters the cell; c - ach is released and diffuses across the axon terminal; d - a nerve signal arrives at an axon terminal; e - ligand - gated sodium channels open and sodium enters the cell. multiple choice d,b,c,e,a d,b,e,a,c b,c,d,e,a b,d,c,a,e

Explanation:

• First, a nerve signal arrives at an axon terminal (D).
• Then, voltage - gated calcium channels open and calcium enters the cell (B).
• Next, ACh is released and diffuses across the axon terminal (C).
• After that, ligand - gated sodium channels open and sodium enters the cell (E).
• Finally, a postsynaptic potential is produced (A).

Answer:

D, B, C, E, A
