2018-08-05 · Nerves are sensory if they consist of dendrites only, motor if they consist of axons only, and mixed if they consist of both. Glial Cells Glial cells , sometimes called neuroglia, do not conduct nerve impulses but perform a number of support functions for nervous tissue. It is well documented that the IHC ribbon synapse function drives auditory nerve activity, both in the absence and in the presence of sound (9, 31). Fatigue in IHC exocytosis could be responsible for adaptation in auditory nerve activity. The anatomy of nerves. The nervous system is one of two key control systems of the body that sends and receives messages, enabling us to function properly.

Up Next. - Synapse, also called neuronal junction, the site of transmission of electric nerve impulses between two nerve cells (neurons) or bet The nervous system is one of two key control systems of the body that sends and receives messages, enabling us to function properly. It is able to do this because of the nerves that connect the brain and spinal cord with our peripheral regions (legs and arms) and viscera (organs).

Nerve cells are responsible for carrying all external and internal signals to a specific target. Signals are transmitted from one nerve cell (neuron) to another. Between these cells there is a small gap called the synapse.

Nerve impulses can’t pass directly across the gap, communication is by means of chemical called a neurotransmitter. Examples of neurotransmitters The Structure and Function of Synapses A study of nerve conduction velocity, late responses and neuromuscular synapse functions in organophosphate workers in India. Misra UK(1), Nag D, Khan WA, Ray PK. Author information: (1)Department of Neurology, Sanjay Gandhi Post Graduate Institute of Medical Sciences, Lucknow, India. Here is how neurons (nerve cells) communicate: An electrical signal travels down the axon. Chemical neurotransmitter molecules are released into the synapse. The neurotransmitter molecules bind to receptor sites on the releasing neuron and the second neuron.
