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.

Typically, a stimulus causes ionic changes in the receptor neuron's dendrites, which lead to the formation of action potentials in the receptor neurons. These action potentials travel the sensory neuron, which connects to a motor neuron (and possibly an ascending neuron) in the spinal cord.The action potential causes neurotransmitter release within the presynaptic cell. The neurotransmitter binds to the postsynaptic cell and elicits an action potential there.he nervous system has many types of sensory neurons. Nerve endings on one end of each neuron are encased in a special structure to sense a specific stimulus. 1  Chemoreceptors sense chemicals. 2  The olfactory bulb that monitors your sense of smell has chemoreceptors that sense odors (chemicals in the air).
