The Endocrine System
Laszlo Vass, Ed.D. Version 42-0023-01-01
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.
-The purpose of this lab is to describe and identify the major endocrine glands.
-We are using slides and a microscope so there are no safety concerns.
Exercise 1: The Pituitary Gland
Observations
Please describe in detail the structures and features you observed on the pituitary gland slide.
-The pituitary gland was broken down into 2 slides, the anterior and the posterior.
-The anterior pituitary gland slide is composed of chromophobes and acidophiles. Chromophobes appear more pale on the slide. Acidophiles are darker in color.
-The posterior pituitary slide is composed of pituicytes and herring bodies. The pituicytes is a glial cell of the posterior pituitary. Herring bodies are lightly colored and represent the terminal end of the axons from the hypothalamus.

Data Table 1: Do some research and fill in the data table below.
Hormone
Functions
Adrenocorticotropic hormone (ACTH)
Stimulates the adrenal cortex, it also stimulates secretion of glucocorticoids.
Antidiuretic hormone (ADH)
Helps maintain blood pressure, blood volume and water content by controlling the concentration of urine made by the kidneys.
Follicle stimulating hormone (FSH)
It regulates the functions of both the ovaries and testes.
Growth hormone (GH)
Helps to maintain normal body structure and metabolism, including helping to keep blood glucose levels within set levels.
Luteinizing hormone (LH)
One of the main hormones that control the reproductive system.
Melanocyte stimulating hormone (MSH)
Important for protecting the skin from UV rays,
