These cells are often used in afferent nervous system function, which means that it involves the senses. How the structure of a neuron allows it to receive and transmit information. Nerve cells normally express a combination of different transmitters, and the combination of transmitters sometimes gives an indication of the function. These cells surround nerves to hold them in place, supply neurons with nutrients and oxygen, insulate the pathways between nerves, and ensure neurons do not become infected. Try refreshing the page, or contact customer support. Depending upon function, these cells can be divided into sensory neurons, interneurons, and motor neurons. Neuron Cell Body The structure of a neuron allows the transmission to be quick. Select a subject to preview related courses: As we already noted, the soma of a multipolar neuron has dendrites, which receive electrical messages from other cells. Cells of the nervous system, called nerve cells or neurons, are specialized to carry "messages" through an electrochemical process.The human brain has approximately 86 billion neurons. It is from here that the electrical firing known as an actionpotential usually occurs. Impulses are carried along one or more of these fibres, called dendrites, to the cell body; in higher nervous systems, only one fibre, the axon, carries the impulse away from the cell body. Nerve Cell Functions The principal function of nerve cells is to generate the electric nerve impulses, process, transmit and receive them between various organs. imaginable degree, area of It is the main component of nervous tissue in all animals except sponges and placozoa.

It is the job of these specialized cells to transmit information throughout the body to enable it to function. When a nerve impulse reaches the terminus of a given nerve cell, it must bridge the tiny gap separating that cell from the next. In order to do this job, the nervous system employs the use of specialized cells, and these cells relay the messages to the necessary tissues, organs, and systems. Nerve cells, also known as neurons, relay messages from the nervous system to coordinate other system activities. Schwann cells are specific to the peripheral nervous system, which consists of all of the nerve cells outside of the brain and spinal cord. Let's review. -Nerve impulse to synaptic knob of presynaptic cell-neurotransmitter released-NT binds to receptors of postsynaptic (action potential of axon)-NT removed by enzyme/recycled by presynaptic terminal knob Through this electrical message, known as an action potential, neurons are able to initiate action in the cells they target.
