MEDICAL PHYSIOLOGY

Detailed explanation-1: -A neurotransmitter is a chemical that relays signals across the synapses between neurons. Neurotransmitters travel across the synaptic space between the terminal button of one neuron and the dendrites of other neurons, where they bind to the dendrites in the neighbouring neurons.

Detailed explanation-2: -Excitatory. Excitatory neurotransmitters “excite” the neuron and cause it to “fire off the message, ‘’ meaning, the message continues to be passed along to the next cell. Examples of excitatory neurotransmitters include glutamate, epinephrine and norepinephrine.

Detailed explanation-3: -When neurons communicate, the neurotransmitters from one neuron are released, cross the synapse, and attach themselves to special molecules in the next neuron called receptors. Receptors receive and process the message, then send it on to the next neuron.
