$\sim$ $\huge\underline\mathcal {Synapse}$

$\implies$In the nervous system, a synapse is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or to the target effector cell.

$\implies$The function of the synapse is to transfer electric activity (information) from one cell to another. The transfer can be from nerve to nerve (neuro-neuro), or nerve to muscle (neuro-myo).

$\sim$ $\huge\underline\mathcal {Neurotransmitters}$

$\implies$Neurotransmitters are endogenous chemicals acting as signaling molecules that enable neurotransmission.

$\implies$There are more than 40 neurotransmitters in the human nervous system; some of the most important are acetylcholine, norepinephrine, dopamine, gamma-aminobutyric acid (GABA), glutamate, serotonin,etc....

$\sim$ $\huge\underline\mathcal {Sensory\: Neuron}$

$\implies$Sensory neurons are nerve cells within the nervous system responsible for converting external stimuli from the organism's environment into internal electrical impulses.

4.]

$\sim$ $\huge\underline\mathcal {Motor neuron}$

$\implies$A motor neuron (or motoneuron) is a neuron whose cell body is located in the motor cortex, brainstem or the spinal cord, and whose axon (fiber) projects to the spinal cord or outside of the spinal cord to directly or indirectly control effector organs, mainly muscles and glands.
