The sliding filament theory discussion

Directions:

The process of muscle contraction is incredibly complex and includes many steps, substances, and impulses.

In your initial post:

For your initial discussion post, choose one component of the sliding filament theory and explain why it is essential to the process of muscle contraction. Describe where the component is found within the sarcomere and the function it serves. Use your own words to create your discussion post and choose your topic from this list:

• Actin
• Myosin
• Troponin
• T-tubules
• Sarcoplasmic reticulum
• Acetylcholine
• Action potential

Example: Calcium

Calcium is stored in the sarcoplasmic reticulum. Stored calcium ions are released from the sarcoplasmic reticulum and bind to troponin. This reveals the binding site for myosin heads to attach.
