Role of Neurotransmitters in Neural Communication

Medium Unit 2: Biological Bases Neural Communication

In the process of neural communication, neurons transmit information through a complex system of electrical and chemical signals. When a neuron is stimulated, it generates an action potential that travels down its axon, ultimately leading to the release of neurotransmitters into the synaptic cleft. This communication process is essential for various functions in the nervous system. Which of the following best describes the role of neurotransmitters in this process?

They create action potentials when a neuron's membrane is depolarized.

They are solely responsible for the propagation of the action potential along the axon.

They facilitate communication between neurons by binding to receptors on the postsynaptic membrane.

They are responsible for recharging a neuron's resting potential after an action potential.

They directly stimulate muscle contractions in all types of movement.
