When a neural impulse reaches the end of an axon,it causes the tiny oval sacs at the end of the axon to release chemicals called __________.
A)effectors
B)neurotransmitters
C)stimulants
D)ions

Question

Quizplus · Accepted Answer

The tiny oval sacs at the end of an axon are called synaptic vesicles, and they release chemicals called neurotransmitters when a neural impulse reaches the end of the axon. The neurotransmitters then travel across the synaptic gap and bind with receptor sites on the dendrites of the next neuron or on an effector cell. Therefore, option B is the correct answer. Options A, C, and D are incorrect as they do not accurately describe the process that occurs at the end of an axon.
