Laboratory 8 - Endocrine System
Endocrine Gland Histology
PhysioEX 9.0 – Endocrine System Physiology (Exercise 4)
Endocrine Gland Histology
Objectives
1. To understand the function of the endocrine system
2. To learn about the major endocrine glands, the hormones they produce, and the effects they initiate
3. To familiarize the student with histological identification of various endocrine glands
Background
The endocrine system consists of cells and tissues that secrete chemical messengers, called hormones, into the blood. The hormones are transported in the blood, via the circulatory system, to target cells. Once the hormone reaches the target cells and binds to a specific receptor, either on the cell membrane or within the cell cytoplasm or nucleus, it can initiate a response that will facilitate homeostasis in the body.
Questions
1. What are some of the major endocrine glands?
2. List the three major categories of hormones. Identify specific hormones within each category.
Procedure
Using the microscope, examine the indicated endocrine glands. Draw a picture, identify any indicated structures within the gland, and answer the questions in each section.
PANCREAS
__________ Total Magnification
1. Identify a pancreatic islet.
2. What major hormone is secreted by the alpha cells? Beta cells? What are the primary effects of each hormone?
3. Describe a pathophysiological condition associated with the pancreas (describe condition, symptoms and treatment).
ADRENAL GLAND
__________ Total Magnification
1. Identify the adrenal cortex and the adrenal medulla.
2. What major hormones are secreted by the adrenal cortex? Adrenal medulla? What are the primary effects of each hormone?
3. Describe a pathophysiological condition associated with the
