NRSC 2100 Study Guide - Final Guide: Medial Forebrain Bundle, Paraventricular Nucleus Of Hypothalamus, Solitary Tract
Document Summary
Peripheral leptin cells release leptin into blood (increased fat content: 2. Reaches leptin receptors on the neurons in the arcuate nucleus of the hypothalamus: 3. Cart peptides (anorectic peptides reduce appetite: 4a. Activates paraventricular nucleus neurons which release acth and tsh, and project into to intermediolateral gray matter of spinal cord (sympathetic activation: pituitary responsible for tsh and acth production - hormones, 4b. Inhibit lateral hypothalamus: reduces feeding behaviors (somatic: decreased leptin levels, 1. Activated arcuate nucleus neurons (different) release npy and. Paraventricular nucleus inhibited reduces acth and tsh, which activates parasympathetic nervous system: 2b. Ventral tegmental area (vta): produce dopamine: 2. Subfornical neurons send axons to pvh: 3. Pvh releases vasopressin (adh) from posterior pituitary: 4. Vasopressin in blood signals kidneys to retain more water: mechanoreceptors (baroreceptors) in walls of large arteries and heart signal loss of blood pressure to hypothalamus via vagus nerve and nucleus of solitary tract, 2.
