What type of neurotransmitters are there? What are neurotransmitters? A neurotransmitter is a chemical substance that releases at the end of a nerve fiber by the arrival of a nerve impulse. It’s released by diffusing across the synapse or junction, causes the transfer of the impulse to another nerve fiber, a muscle fiber, or some other structure.  There are many different ways to classify neurotransmitters. Dividing them into amino acids, peptides, and monoamines is sufficient for some classification purposes.

Major neurotransmitters:

Neurotransmitters – are the chemicals that allow the transmission of signals from one neuron to the next across synapses (junction of 2+ neurons). Neurotransmitters are found at the axon endings of motor neurons.

Dopamine – produces feelings of pleasure when released by the brain reward system. Multiple functions but it are usual inhibitory.

Glycine – Used mainly by neurons in the spinal cord. As a result of its position, it almost always acts as an inhibitory neurotransmitter.

Serotonin – Involved in many functions including mood, appetite, and sensory perception. in the spinal cord, Serotonin is inhibitory in pain pathways.

Norepinephrine – A neurotransmitter and a hormone. Part of fight or flight response. Also regulates normal brain process. is usually excitatory but it’s inhibitory sometimes.

Acetylcholine – Used by spinal cord neurons to control muscles. Also used in the brain to regulate memory. it is usually excitatory.

Gaba – (gamma-aminobutyric acid) Main inhibitory neurotransmitter of the brain. Because of this role, it’s the main papa and king of the other neurotransmitters.

Glutamate – Most common excitatory neurotransmitter in the brain. Because of this proliferation, nearly all excitatory neurons are glutamatergic, and over half of all brain synapses release this agent.

Adrenaline – Works with norepinephrine and dopamine, to act as a catecholamine – a group of hormones released in a response to stress. These three hormones react with various body tissues, preparing the body to react physically to the stress causing the situation.

Endorphins – interact with the opiate receptors in the brain to reduce the perception of pain. As a result, this leads to feelings of euphoria, modulation of appetite, the release of hormones, and enhancement of the immune response.
