- 1. Explain the process of how your body uses hormones to increase body temperature when an individual experiences a drop in body temperature in her extremities. 2. Explain using an example how hormones can have an inhibitory response and why this would happen in the human body. 2-3 sentences for both, ASAP5. explain how the concept of cell to cell communication as it applies to the endocrine system.

- 1. Explain how the nervous system and endocrine differ: 1. the rate of their control, 2. the way in which they communicate with body cells; and 3. the types of the body processes they control5. Each of the following observations were made in a lab rat after a specific gland or organ (or part of one) was removed. State what was removed in each case (be as specific as possible!) and briefly explain why the observed effect took place. NOTE: Assume the endocrine system of a rat works the same as that of a human. Observation What Was Explanation Removed? TSH levels in the blood increase significantly A stressful stimulus (a siren) caused an increase in heart rate but did not result in the increased breakdown of protein in muscle Blood levels of T3, T4, Cortisol, Growth Hormone all decreased drastically but levels of epinephrine and norepinephrine did not change.2. Fill in the chart below: ORGAN LOCATION HORMONES TARGET FUNCTION PRODUCED ORGAN Hypothalamus Stimulate release of gonadotrophins (FSH, Anterior LH) pituitary gland Ventral to Follicle-stimulating hormone (FSH) Ovaries hypothalamus Stimulates ovulation, conversion of follicles to the corpus luteum (CL), and secretion of progesterone Ovaries Mammary glands Prolactin Ventral to Uterus Posterior hypothalamus pituitary gland Stimulates milk letdown from mammary gland into nipples Uterus, vagina Ovarian follicle CL Progesterone Hypothalamus Inhibits GnRH from hypothalamus and FSH Hypothalamus Anterior Abdomen Ovary
