ANATOMY

Detailed explanation-1: -Transmission of impulse across synapse takes place by chemical neurotransmitters. An example of such neurotransmitters is acetylcholine.

Detailed explanation-2: -Neurotransmitter – A chemical released from a neuron following an action potential. The neurotransmitter travels across the synapse to excite or inhibit the target neuron. Different types of neurons use different neurotransmitters and therefore have different effects on their targets.

Detailed explanation-3: -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-4: -Neurotransmitters pass through the synapse, the gap between two nerve cells, and attach to receptors on the receiving cell. This process repeats from neuron to neuron, as the impulse travels to its destination-a web of communication that allows you to move, think, feel and communicate.

Detailed explanation-5: -Chemical synapse allows unidirectional transmission by using chemicals called neurotransmitters to send signals along the neurons.
