THE MUSCULAR SYSTEM

Lab Objectives

Students should be able to:

1. identify three types of muscle tissue and associated parts microscopically

2. identify various human muscles.

3. identify various muscles on a preserved cat.

I.   MUSCLE HISTOLOGY: Use the microscope, prepared slides, and text or atlas references to study tissue samples of the three muscle tissue categories. Learn to recognize the differences  between them, and  know the specific characteristics of each:

II. MUSCLE ANATOMY: Identification of selected skeletal muscles on torsos, models, and preserved cats.
