The Major Excitatory Neurotransmitter of the Human Brain Is

Question

The major excitatory neurotransmitter of the human brain is
A)acetylcholine.
B)epinephrine.
C)glutamate.
D)nitric oxide.
E)GABA.

Accepted Answer

Glutamate is the major excitatory neurotransmitter of the human brain, responsible for stimulating neurons and enhancing nerve transmission. It plays a role in learning, memory, and neural plasticity. Acetylcholine, on the other hand, is involved in muscle contraction and cognitive function, while GABA is the major inhibitory neurotransmitter. Epinephrine and nitric oxide also have important roles in the brain, but they are not the primary excitatory neurotransmitter.
