Lab 8: Muscle and Nervous Tissue



Lab 17: Skeletal Muscle Structure

PURPOSE:

To review the structure of a skeletal muscle

LEARNING OBJECTIVES:

1. Describe how connective tissue is associated with muscle tissue within a skeletal muscle

2. Name and locate the major parts of a skeletal muscle fiber

PROCEDURE:

1. Review the Structure of Skeletal muscle tissue in Cpt 7 pages 178-182, and the Skeletal Muscle Tissue page

2. Reexamine the microscopic structure of skeletal muscle tissue by examining the HistoWeb slides 1-7. Draw a picture of slides 2 and 7 in your Lab Notebook and label the following: muscle fiber, nuclei, striations, myofibrils

3. Print out the images below, paste them into your Lab Notebook and label figures 17.1, 17.2, and 17.3

4. Complete Part A in your Lab Notebook

5. Draw an image of a muscle fiber so that it includes the following labeled items: sarcolemma, sarcoplasm, mitochondria, myofibril (myosin and actin filaments), sarcomere (A & I bands and Z line), sarcoplasmic reticulum, transverse tubules, opening to T-Tubes

6. Complete Part B and Part C in your Lab Notebook

7. As you complete the lab, Review the "Lab Objectives" from the handout and write a synopsis of the lab addressing the two objectives.
