GENERAL HISTOLOGY

Detailed explanation-1: -Neurotransmitters: These are chemicals secreted by when a stimulus is detected. They are secreted by the axons of one neuron and then transmitted to the dendrites of another neuron, which then gets excited and generates and carries the impulse forward. Acetylcholine is the most common neurotransmitter in our body.

Detailed explanation-2: -A nerve cell (neuron) communicates with other cells through electrical impulses when the nerve cell is stimulated. Within a neuron, the impulse moves to the tip of an axon and causes the release of neurotransmitters, chemicals that act as messengers.

Detailed explanation-3: -As briefly described in the preceding chapter, neurotransmitters are chemical signals released from presynaptic nerve terminals into the synaptic cleft.
