These fibers transmit their message still farther; in the simplest case, to other fibers that go directly to the effectors, the muscles and glands that are the organs of action. Nerve fibers that lead to the effectors are called efferent nerves. The transmission path from receptors to effectors is usually more circuitous than this. The afferent fibers often bring their messages to intermediate nerve cells, or inetneurons, in the brain or spinal cord. These interneurons may transmit the message to the efferent nerve cells or send it on to yet other inetneurons. Typically many thousands of such inetneurons have been 'consulted' before the command to action is finally issued and sent down the path of the efferent nerve fibers. Nerve Cell and Nerve Impulse: The neuron is the simplest element of nervous action. It is a single cell, with three subdivisions: the dendrites, the cell body, and the axon
