One important difference between autonomic neurons and somat

One important difference between autonomic neurons and somatic neurons is the location of synaptic vesicles, which are found in  ___ in the Autonomic Nervous System.

Solution

            The synaptic vesicles of a neuron or nerve cell contain neurotransmitters, which are released at the synapse, when mediated by voltage-dependent calcium channel. The synaptic vesicles are also called as neurotransmitter vesicles. In fact they occur as pools within the nerve terminals which are of three types: readily releasable pool, recycling pool, and reserve pool.

            The vesicles are essential for transmitting nerve impulses between neurons. The area of the axon containing the groups of vesicles is called an axon terminal or \"bouton\". At a stimulation of 0.2 Hz, over 10 minutes, about 130 vesicles are released per bouton. In the human brain, the V1 synaptic vesicles are estimated to have an average diameter of 39.5 nanometers.

            The autonomic nervous system (the involuntary system) is the part of the peripheral nervous system that regulates the basic visceral processes. It operates independently of voluntary control, although stress, fear, excitement, and differences in the sleep-wake cycle; change the extent of autonomic activity. It controls processes like circulation, digestion, respiration, temperature, sweating, metabolism, and some endocrine gland secretions.

            The Sympathetic system is most active when the body responds to the changes in the internal or external environment involving regulation of temperature and sugar levels; and the response to hemorrhage and oxygen deficiency.

Answer: The synaptic vesicles are found in axon terminal or \'bouton\' of neurons in the Autonomic Nervous System.
