Question

A preganglionic sympathetic nerve cell, with an axon terminal in the superior cervical ganglion, that releases acetylcholine onto a postganglionic sympathetic nerve cell is an example of which type of signaling?

Answer 1

neurotransmission

Step-by-step explanation:

• When the nerve impulses are transmitted from one neuron to another or from one neuron to a muscle, then such a type of signalling is known as neurotransmission.
• When neurotransmission occurs between two nerves, then the neurons communicate by release a neurotransmitter into the synapse between the two neurons.
• The neurotransmitters are released by the axon terminals from the presynaptic neuron and they bind onto the dendrites of the postsynaptic neurons.
• Therefore, in the given example the release of acetylcholine (neurotransmitter) from the preganglionic nerve cell onto the postganglionic nerve cell is an example of neurotransmission.
