Summary NSG 552 Psychopharmacology Exam 1 Study Guide LATEST 2024. DOPAMINE • Dopamine belongs to the family of catecholamines. It is a neurotransmitter. • Hormones, Epinephrine and Norepinephrine (other catecholamines) are derived from Dopamine • Dopamine plays a significant role in learning, goal-directed behavior, regulation of hormones, motor control. DOPAMINE SYNTHESIS Phenylalanine (amino acid from diet) -> phenyalanine hydroxylase -> Tyrosine -> Tyrosine hydroxylase ...

CBNS 120 Final Test Questions & Answers 2024/2025 Santiago Ramón y Cajal, 1885-90 (Neurons and Signalling) - ANSWERSPrinciple of Dynamic Polarization - Information flows in a predictable and consistent direction within a nerve cell. - Information flow begins at the receiving (input) sites on the dendrites and soma to the trigger zone at the axon hillock (initial segment). - At the axon hillock, the action potential is initiated and propagated unidirectionally along the axon to the p...

When the presynaptic cell contacts a muscle cell, the synapse area is called a motor end plate. - ANSWER TRUE Briefly explain why the action potential flows only from the axon hillock to the terminal web. - ANSWER During the course of an action potential there is a refractory period that makes sure the action potential can't trigger backwards by the use of caps on gated sodium channels. The caps close and keeps the action potential flowing in one direction. How do the glial cells (i.e., m...
