Module 1: The Endocrine System

Introduction

Welcome to the endocrine system lab, the first hands-on module in your Anatomy and Physiology II Laboratory course. During this lab, you will examine the body’s major endocrine glands—such as the pituitary, thyroid, adrenal glands, pancreas, and gonads—and learn about the hormones they produce. Using anatomical models, microscope slides, and interactive activities, you will identify endocrine tissues, observe their microscopic features, and analyze their physiological roles. You’ll also investigate how the endocrine system interacts with other body systems to adapt to internal changes (like stress or blood sugar fluctuations) and external stimuli (such as temperature or environment). This lab will help you draw connections between the structure and function of endocrine organs and the effects of hormonal imbalances. Understanding the endocrine system is essential for recognizing how disruptions in hormone levels can lead to conditions such as diabetes, thyroid disorders, or adrenal insufficiency.

• Describe the overall function of the endocrine system
• Describe the functions of the individual organs and structures of the endocrine system
• Identify the structures of the endocrine system and associated parts on a model, in a picture or diagram, or in a specimen.
• Identify and describe the histologic structures of the endocrine system in a microscope slide.
• List the hormones secreted by the endocrine organs, and identify their site of origin

To achieve these objectives: 

1. Read Chapter 1 in the textbook and Chapter 1 in the lab manual.
2. Complete the Chapter 1 Pre-Lab exercises and Module 1 Quiz before the DUE DATE (see the Course Calendar). 
3. Complete the Chapter 1 Lab Exercises [in-class or online].

Note the check boxes to the right that help you track your progress: some are automatic, and some are manual. [Delete in subsequent modules.]
