Neurotransmitters. With the regard to the process of the neural transmission, a refractory period refers to the time in interval in which. the Positively charged sodium ions are to pumped back to outside a neural membrane.
Neurotransmitters are the chemical messengers that your body can't function without it. Their job is to carry out chemical signals (“messages”) from one of the neuron (nerve cell) to the next target cell. The next target of the cell can be another nerve cell, a muscle cell or the gland.
Fortunately, the seven “small molecule” are neurotransmitters (acetylcholine, dopamine, the gamma-aminobutyric acid (GABA), or glutamate, histamine, norepinephrine, and the serotonin) do the majority of the work.

Neurosecretory cells make and release the hormones from the posterior pituitary. The cell bodies of these neurosecretory cells receive synapses from Afferent neuron and their axon terminals release hormones into blood stream or the local extracellular space.
Neurohormone is generally produced by neurosecretory cells and liberated by nerve impulses. Neurosecretory cells receive synapses from afferent neurons to guide magnocellular neurons .
A synapse is known as a small junction at the end of a neuron that allows any signal to pass through one neuron to another. Synapse is a junction were the one neuron get connected with the other neuron .
