Characteristics of Neurotransmitter Action

Medium Unit 2: Biological Bases Neural Communication

Neural communication is essential for transmitting signals within the nervous system. This process involves the release of neurotransmitters that can either excite or inhibit the firing of adjacent neurons. Understanding how these neurotransmitters function and their interactions at synapses is crucial for grasping the biological bases of behavior.

Which of the following statements accurately describes a characteristic of neurotransmitter action in the human brain?

Neurotransmitters only function to inhibit neuronal firing.

All neurotransmitters have the same function regardless of their type.

Neurotransmitters can bind to different types of receptors, leading to varying effects.

Neurotransmitters act solely in the synapse and do not affect any other neurons.

Neurotransmitter action is always immediate and irreversible.
