NEET PG DENTAL EXAM

Detailed explanation-1: -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-2: -When the nerve impulse reaches the dendrites at the end of the axon, chemical messengers called neurotransmitters are released. These chemicals diffuse across the synapse (the gap between the two neurons). The chemicals bind with receptor molecules on the membrane of the second neuron.

Detailed explanation-3: -Thus, nerve impulse move across the synapse, using chemicals called neurotransmitters. Hence, answer is ‘Adrenaline and noradrenaline’

Detailed explanation-4: -Communication between neurons largely happens at the chemical synapse, where neurotransmitters are released from presynaptic vesicles, cross the narrow synaptic cleft, and activate receptors on the postsynaptic neuron.
