Purpose
What is the purpose of this exercise? Are there any safety concerns associated with this exercise? If so, list what they are and what precautions should be taken.
Students will identify the major endocrine glands and tissues of the body. Students will relate each endocrine gland to the appropriate hormone. Students will explain how each hormone helps the body maintain homeostasis. Students will identify the histology of the major endocrine glands and relate it to their structure and function.

What does testosterone do?
Testosterone stimulates the development of the male reproductive system in the fetus and adolescent. It also stimulates the development of masculine physique and sex drive in adolescence. Testosterone is also responsible for sustaining sperm production and sexual instinct throughout adult life.
C. What are the endocrine functions of the ovaries?
The ovaries secrete estradiol, progesterone, and inhibin. D. What do estrogen and progesterone do?
Estrogen and progesterone are responsible for development of the female physique, female reproductive system, regulation of the menstrual cycle, sustaining pregnancy, and preparation of the mammary glands for lactation.
E. How do birth control pills work in terms of endocrine function?
Birth control pills attempt to deceive the body into thinking it is already pregnant. It does this my increasing either estrogen or progesterone levels to mimic that of a pregnant female. Since the body does not release additional eggs if the female is already pregnant, the likelihood of conception is minimalized by the use of birth control.

Exercise 9: Endocrine System Roundup Questions
A. Describe the effects that a malfunctioning pituitary gland would have on an individual?
A malfunctioning pituitary gland may lead to disorders of other glands or systemic diseases. Some symptoms may include infertility, diabetes insipidus, and inability to regulate other important endocrine hormones.
B. Which endocrine glands would be most affected by prolonged mental stress on the body? (i.e work, lack of time, worrying etc.) Explain your reasoning.
The glands that would be most affected my prolonged mental stress are the adrenal glands. The adrenal glands secrete hormones in response to fear, pain, or stress. Prolonged stress may result in electrolyte imbalance, increased metabolism, and altered sex drive. Prolonged periods of stress may lead to exhaustion of body resources.
C. Explain, in general, how a hormone works.
Hormones are secreted into the bloodstream by endocrine glands. The hormones act upon receptor sites called “target cells”. Hormones will only act upon these specific receptors. Once the hormone reaches the target cell a series of chemical and physiological changes occur, which produce the desired outcome necessary to maintain
