For treatment of later outbreaks of genital herpes, after the first infection, the acyclovir dosage is 200 mg five times a day (about every four hours) for five days, starting at the first signs of an outbreak. The earlier the medication is started, the better it works.
They connect receptors to the central nervous system and also connect one part of the nervous system to another, for example in the brain and spinal cord. They also carry impulses from the nervous system to effector organs, such as muscles and glands. When neurons are stimulated they transmit an electrical impulse.
The cell membrane of a muscle cell is called the sarcolemma, and this membrane, like that of neurons, maintains a membrane potential. So, impulses travel along muscle cell membranes just as they do along nerve cell membranes. However, the 'function' of impulses in muscle cells is to bring about contraction. To understand how a muscle contracts, you need to know a bit about the structure of muscle cells. Skeletal muscle is the muscle attached to the skeleton.
