INTERNAL REGULATION - Coggle Diagram

- - - - increase hunger
    - - increase physical and immune system activity
  - - - produce immune system chemicals to repair the ER
- - - - e.g. fenfluramine & phentermine block reuptake of certain neurotransmitters to produce brain effects similar to of a completed meal
- - - - neurons sensitive to hunger signals
      - neurons sensitive to satiety signals
    - - taste pathways
      - axons releasing ghrelin
  - - - chemical important for limiting food intake
        
        deficiencies of receptor leads to overeating
  - - - NPY & AgRP blocks satiety action of paraventricular nucleus & provokes overeating
  - - - increases animals' persisance in seeking food
      - responds to incentives and reinforcement in general
    - - detecting hunger and sending messages to make food taste better
      - increase digestive secretions
      - increase pituitary gland's secretion of hormones that increases insulin secretion
- - - - resulting from eating salty foods
      - occurs when body maintains combined concentration fixed level at 0.15M
      - salty foods cause Na+ spread through blood and extracellular fluid of cell
    - - resulting from loss of fluids due to bleeding/sweating
  - - - supraoptic nucleus
      - paraventricular nucleus
        
        both control rate of posterior pituitary releases vasopressin
    - - controls drinking
- - - - constrict blood vessels to compensate for a drop in blood pressure
