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.

When the nerve is damaged,the action potential remains between the electrodes and doesn't reach the second electrode (i.e potential difference remains positive and doesn't go into negative phase) , the biphasic action potential changes into monophasic action potential i.e with single phase. Source(s):E: biphasic action potential change into the monophasic action? Why does the biphasic action potential change into the monophasic action potential after nerve injury between the two recording electrodes?
