GFR is related inversely and nonlinearly to serum creatinine. Age, gender, and race all affect muscle mass and, in turn, serum creatinine. Both the MDRD Study and CKD-EPI equations include variables to account for serum creatinine variation with age, gender, and race.
When a nerve is stimulated, its cell membrane is depolarised so that the inside of the cell becomes less negative. The potential is conducted along the axon to the axon termin â¦ al.At the dendrite it stimulates the release of a chemical transmitter, which diffuses across a synapse.The transmitter binds to receptor sites on the postsynaptic cell membrane to stimulate the generation of another impulse.+ 4 others found this useful.t the dendrite it stimulates the release of a chemical transmitter, which diffuses across a synapse.

One part of this transmission process involves what is known as an action potential. An action potential is part of the process that occurs during the firing of a neuron. During the action potential, part of the neural membrane opens to allow positively charged ions inside the cell and negatively charged ions out. This process causes a rapid increase in the positive charge of the nerve fiber.
