  4. Fxn of GI hormones in digestive movements
  5. Pelage
  1. a fur color in mammals; ex: short tailed weasel, white fur in winter (inc aMSH), brown fur in summer (dec aMSH)
  2. b Flux in and out of blood in a controlling point; balance of glucose production and utilization; hormone regulators: insulin, glucagon, cortisol, epi, GH; improtant tissues that regulate glucose; liver, adipose tissue, muscle
  3. c suffix: tropes; ex: gonadotropes (synthesize LH, TSH)
