A: A high BUN count usually indicates that the kidneys are not working properly, but there are other issues that can cause high results, as stated by Mayo Clinic. Some other causes for a high BUN count are a high protein diet, dehydration and congestive heart failure.
A single axon usually transmits electrical impulses away from the cell body to other neurons. Electrical messages ordinarily travel in only one direction: Information comes into a cell through a dendrite, is processed in the cell body, and passes through the axon.he electrical charge in the neuron travels down the axon by means of a chemical process that is different from, and much slower than, a household electrical current.

An impulse begins when a neuron is stimulated by another neuron or by a stimulus in the environment. The cell membranes begin to change the flow of ions and a reversal of charges, the action potential, results. An impulse that changes one neuron, changes the next.ppropriate responses are carried out by effectors (a muscle or gland). The Neuron. The neuron, a nerve cell, is the functional unit of the nervous system that carries the impulse (the message) to the appropriate part of the nervous system or interprets the impulse and allows a response.
