Document Summary

Newly synthesized synaptic vesicles from the golgi containing precursors of neurotransmitters. These rules do not apply to all neurotransmitters. Ex) glucocorticoids (adrenal glands) influence the synthesis of norepinephrine by. Conservative of the same code over millions of years of evolution. The neuropeptides must be returned to the soma to be recycled. Amino acids: contain an amine group (-nh2) and a carboxyl group (-cooh) Acetylcholine: quaternary amine because of a nitrogen and 4 methyl groups. Small, water soluble molecules that are ionized at physiological ph, thus reducing their tendency to diffuse through the blood brain barrier. Neuropeptides: 3-40 amino acids derived from protein precursors synthesized in the cell body, they are packed into vesicles by the golgi and then transported via axonal transport to the nerve terminal for release, which is a slow process. 8. when the neurotransmitter binds to the receptor: epsp, endocytosis via endosomes.
