  1. Chapter 9 Homeostasis & Behavior & Further Discussion of the Posterior Pituitary

  2. 9.2 The thermostat is a common homeostatic device

  3. 9.3 Behavioral thermoregulation in iguanas (Part 2)

  4. 9.3 Behavioral thermoregulation in iguanas (Part 1)

  5. 9.3 Behavioral thermoregulation in iguanas (Part 3) Iguanas were injected with an infectious agent and their survival was correlated with the temperature they were kept.

  6. 9.4 Body fluid is maintained in separate, but interacting, compartments

  7. 9.5 Osmosis

  8. 9.6 Osmotic thirst

  9. 9.7 Two types of thirst result from different osmotic conditions Loss of fluids and solutes…. Such as in blood loss. CELL “DEHYDRATION”

  10. 9.8 Rating of thirst after water deprivation (Part 1)

  11. 9.8 Rating of thirst after water deprivation (Part 2)

  12. 9.9 Vasopressin (ADH) mediates water consumption Brattleboro rats lack Vassopressin (ADH) and are therefore perpetually thirsty.

  13. 9.10 Brain structures involved in the mediation of thirst and water intake

  14. 9.11 Schematic model of fluid regulation

  15. H. H. Dale – made the connection between extracts from the pituitary and the effect of uterine contraction.

  16. Flank marking and grooming behavior (Mean ± SEM) following microinjection of arginine vasopressin (10 μM in 100 nl saline) in the anterior hypothalamus of golden hamsters treated with vehicle (Veh), clomipramine (Clom), desipramine (Des), and fluoxetine (Fluox). All animals were treated with 2 mg/day for 2 weeks. Craig F Ferris, Mads F Rasmussen, Tara Messenger and Gary Koppel University of Massachusetts ( Primary Research Group )

  17. The neurohypophysial peptide, arginine vasotocin (AVT), is thought to function as an antidiuretic hormone in reptiles, helping to limit water loss from the kidneys by reducing the rate at which blood is filtered and also by facilitating water re-absorption in the kidney tubules.

  18. 9.12 Synthesis of angiotensin in humans A protein hormone, causes blood vessels to constrict, and drives blood pressure up.

  19. 9.15 Adrenalectomy affects saline preference thresholds

  20. 9.16 Metabolic interactions among the major components of energy balance in the well-fed state

  21. 9.17 Metabolic interactions among the major components of energy balance in the fasting state

  22. 9.18 Leptin and insulin act as peripheral signals

  23. 9.20 Current model of the role of the arcuate nuclei in monitoring metabolic fuels (Part 1)

  24. 9.20 Current model of the role of the arcuate nuclei in monitoring metabolic fuels (Part 2)

  25. 9.22 Neural control of feeding in the blowfly

  26. 9.24 The role of the liver in insulin-induced feeding (Part 1)

  27. 9.24 The role of the liver in insulin-induced feeding (Part 2)

  28. 9.25 Effects of ovariectomy and progesterone treatment on body mass

  29. 9.26 Annual body mass changes for three ground squirrels

  30. Box 9.1 Vertebrate Renal Function
