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.

For the nerve cell, this equilibrium is disturbed by the arrival of a suitable stimulus. The dynamic changes in the membrane potential in response to the stimulus is called an action potential. After the action potential the mechanisms described above bring the cell membrane back to its resting state.or the nerve cell, this equilibrium is disturbed by the arrival of a suitable stimulus.
