Quantal or Graded Secretion of Adrenal Medullary Hormone and Sympathetic Neurotransmitterinitial work was done on the skeletal neuromuscular endplate, but it appears that the postjunctional membrane potential (MP) in essentially all neuro-effector junctions so far investigated shows extensive similarities to that of the endplate. Thus in the absence of nerve impulses there are spontaneoErgots 发表于 2025-3-25 13:41:55

Saturation of the Uptake of Noradrenaline as a Determinant of Pharmacological Effectss, the uptake mechanism is characterized by lacking stereospecificity and by being saturable ; however, in spite of the lack of stereospecificity, the rate of uptake of d-noradrenaline is lower than that of the l-isomer when the heart is perfused with a concentration of the amine (200 ng/ml) that caEnzyme 发表于 2025-3-25 21:49:20
