Macroscopic Muscle Anatomy

Macroscopic Anatomy Notes 


Structure of the Muscle Tissue
Do Now: Why dont muscles tear apart completely every time we workout strenuously?
Todays Objective
SWBAT define and explain the role of the macroscopic anatomical features of the skeletal muscle:
¡Endomysium
¡Perimysium
¡Fascicle
¡Epimysium
¡Tendon
¡Aponeurosis
Copy This Diagram Into Your Notes
Structure of the Muscle Tissue


Muscle Fibers are the cells of muscle tissue.
1000s 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.
Raise The Number of Fingers for the Correct Answer for The Question
Connective tissue that surrounds each individual muscle fiber?
1.Endomysium
2.Perimysium
3.Epimysium
4.Fascicle

2.Perimysium
3.Epimysium
4.Fascicle
Raise The Number of Fingers for the Correct Answer for The Question
Connective tissue that surrounds each individual Fascicle?
1.Endomysium
2.Perimysium
3.Epimysium
4.Fascicle
Raise The Number of Fingers for the Correct Answer for The Question
Connective tissue that surrounds bundles of fascicles?
1.Endomysium
2.Perimysium
3.Epimysium
4.Fascicle
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?
