An antagonist

A) blocks the action of neurotransmitters.
B) prevents reuptake of neurotransmitters.
C) mimics the action of a neurotransmitter.
D) extends the absolute refractory period of neural transmission.

Antagonist

In physiology and pharmacology, a substance that inhibits or counteracts the action of a neurotransmitter or hormone; in literature, a character or force opposing the protagonist.

Neurotransmitters

Chemical messengers that transmit signals across synapses from one neuron to another in the nervous system, influencing various bodily functions.

Reuptake

The process by which neurotransmitters are absorbed back into a neuron after they have transmitted a neural impulse across the synapse.

  • Investigate the effects that select neurotransmitters have on neural responses and behavioral manifestations, considering the effects of agonists and antagonists.
  • Discern the impact of substances from outside the body, e.g., drugs, on neural messaging and behavioral patterns.

Final Answer :
A
Explanation :
An antagonist is a substance that blocks the action of neurotransmitters by binding to receptor sites and preventing the neurotransmitter from activating those sites. This decreases the activity of the synapse and can result in a variety of effects on behavior and physiology.
