Muscle Contraction WebQuest
Introduction
Skeletal Muscle Contraction-Spinach Connection
Description: Learn the anatomy and physiology of a muscle contraction using
animations. Project-based assessment concludes the WebQuest.
Grade Level: 11-12
Curriculum: Anatomy
Task 1: Review of muscle contraction concepts.
Watch the following animations in order and then answer the questions that follow.
Neuromuscular junction
1.
What causes voltage-gated calcium ion channels to open?
2. Calcium moving into the neuron causes vesicles to release a neurotransmitter. What’s the name of this
neurotransmitter?
3. What is the name of the enzyme that breaks down Ach?
Action Potentials and Muscle Contractions
4.
Explain what you think a neuromuscular junction is as described in the video.
5.
What is the name of the protein that covers up the myosin binding sites on actin?
6.
Create an analogy that describes the role of troponin & tropomyosin.
7.
How would you describe a cross-bridge? (Appearance & function)
Breakdown of ATP and Cross-Bridge Movement during Muscle Contraction

8.
What is the connective tissue that connects muscle to bone called?
9. What is the connective tissue that separates bundles of muscle fibers?
10. What is the connective tissue that separates individual muscle fibers?

Muscular System, Sliding Filament Theory 2 (YouTube Link----need iPad)
11. Why do you think the mechanism of muscle contraction is referred to as the “Sliding Filament Theory”?
12. Do muscles get longer or shorter when they contract?
Task 2: Summary animation with self-quizzes.
Watch the following animation and answer the three questions below by completing the quiz part of the tutorial.
Muscle Contraction Summary & Quiz
13. The sliding filament theory states that, during muscle contraction and relaxation,
a. Actin & myosin filaments shorten, then lengthen
b. Actin & myosin filaments change positions relative to one another
c. Troponin & Tropomyosin slide past one another
14. During muscle contraction, calcium ions bind to
a. Troponin
b. Tropomyosin
c. Actin
d. Myosin
15. After a myosin head has performed a power stroke, it must first bind to ________ in order to perform another
power stroke.
a. Actin
b. Troponin
c. Tropomyosin
d. ATP
