Macroscopic Muscle Anatomy

Macroscopic Anatomy Notes 

—Structure of the Muscle Tissue

—Do Now: Why don’t muscles tear apart completely every time we workout strenuously?

—Today’s Objective

—SWBAT define and explain the role of the macroscopic anatomical features of the skeletal muscle:

¡Endomysium

¡Perimysium

¡Fascicle

¡Epimysium

¡Tendon

¡Aponeurosis

—Structure of the Muscle Tissue

—Muscle Fibers are the cells of muscle tissue.

—

—1000’s of these fibers are bundled together by connective tissue make a muscle

—Connective Tissue Sheaths

—Connective Tissues that wrap the muscle fibers provide strength and support to the muscle as a whole

—Turn To Your Partner

—Partner A – Discuss what are muscle fibers and what makes up a muscle.

—

—Partner B – Discuss what purpose the connective sheaths in the muscle serves.

—Endomysium

—Endomysium is a connective tissue layer that covers each individual muscle fiber.

—FASCICLE

—A bundle of multiple muscle fibers is called a FASCICLE

—Perimysium

—Perimysium are the connective tissue layers that surround a fascicle.

—Epimysium

—Multiple fascicles are surrounded by the connective tissue layer called the epimysium.

—Tendons & Aponeuroses

—Epimysium blend together to form the tendons or aponeuroses

—

—Tendons & Aponeuroses

—Tendons connect muscle to bone

—

—Aponeuroses connect muscle to another muscle or connective tissue.

—Turn To Your Partner

—Partner A – Explain what a tendon is?

—

—Partner B – Explain what an aponeurosis is?

—Individual Activity

—You may work with your partner – HOWEVER – each individual will complete their own work and turn in their own copy of the assignment.

—

—DO NOT WRITE ON THE WORKSHEET…YOU WILL ANSWER ON YOUR OWN PAPER

—After completing the model, answer the questions on the back of the sheet.

—In Your Groups of 4 Each Person will get enough materials for their entire group:

¡Person 1 –Take One Box/Cup/Jar of Toothpicks

¡

¡Person 2 –Take One Box of Straws

¡

¡Person 3 –Take one Film Canister for each person in your group

¡

¡Person 4 –Take one instruction sheet for each person in your group.

—Discussion of the Activity

1.How does the activity demonstrate the structure of the muscle?

●

2.What does each separate material represent?
