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.

In short, stimulation of the sympathetic branch of the autonomic nervous system prepares the body for emergencies: for  fight or flight  (and, perhaps, enhances the memory of the event that triggered the response).1  a single preganglionic neuron usually synapses with many postganglionic neurons; Here they synapse with. 2  postganglionic neurons, which run to the effector organ (cardiac muscle, smooth muscle, or a gland). 3  sympathetic nervous system and the. 4  parasympathetic nervous system.
