What neurotransmitter is always excitatory?
Glutamate is the primary excitatory neurotransmitter in the central nervous system. It enhances the transmission of signals between neurons by promoting the depolarization of postsynaptic neurons.
What is the neurotransmitter that drugs increase that is responsible for pleasurable feelings?
Dopamine is the neurotransmitter that drugs increase, leading to pleasurable feelings. It plays a key role in the brain's reward system and is associated with motivation, reinforcement, and pleasure.
What is the process of a neurotransmitter being absorbed into the axon terminal?
When an action potential reaches the axon terminal, it triggers the opening of voltage-gated calcium channels. Calcium ions enter the axon terminal, leading to the fusion of neurotransmitter-containing vesicles with the synaptic membrane. The neurotransmitter is then released into the synaptic cleft where it can bind to receptors on the postsynaptic neuron.
What neurotransmitter makes you feel happy?
The neurotransmitter that makes you feel happy is serotonin. It is known for its role in regulating mood, emotions, and overall sense of well-being. Imbalances in serotonin levels have been linked to conditions such as depression and anxiety.

What is the function of norepinophine?
Norepinephrine is a catecholamine with multiple roles including as a hormone and a neurotransmitter.Areas of the body that produce or are affected by norepinephrine are described as noradrenergic. One of the most important functions of norepinephrine is its role as the neurotransmitter released from the sympathetic neurons affecting the heart. An increase in norepinephrine from the sympathetic nervous system increases the rate of contractions
What enzyme breaksdown catecholamine?
monoamine oxidase and catechol-O-methyltransferase
Which of the following helps carry nerve impulses across the synapse?
neurotransmitter carries the nerve impulses from neuron to neuron across a synapse
The receptors for catecholamine and polypeptide hormones are found?
on the outer surface of the target cell
