MCQ IN MEDICINE

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

Detailed explanation-3: –When the nerve impulse passes through the first axon and reaches the dendrites at the end of the axon, chemical messengers called neurotransmitters are released.-Neurotransmitters travel through the synapse between the axon and the dendrite of the next neuron and bind to the dendrite membrane.

Detailed explanation-4: -A nerve impulse is transmitted to another cell at either an electrical or a chemical synapse . At a chemical synapse, neurotransmitter chemicals are released from the presynaptic cell into the synaptic cleft between cells.
