Skeletal Muscle Contraction

List the 6 steps of muscle contraction

1. Which of these steps required energy? Why?

2. Which of these steps results in the most movement?

3. Give two examples of actions you use skeletal muscles contraction to

complete

Skeletal Muscle Anatomy

Connective tissue

1. ___________________Connect muscle to bone

2. An skeletal muscle is surrounded by a connective tissue layer called

_____________. This was observed in the chicken wing dissection. What did it

look like?

3. ___________________ surrounds fascicles (bundles of muscle cells) and create

passages for nerves and blood vessels

4. _________________ surrounds and protects individual muscle cells/fibers

Muscle Fibers

1. Sarcomeres are _________________________________________________________

2. The movement proteins in sarcomeres are __________________ and _______________

3. Thin filaments are made of primarily______________

4. Thick filaments are made of primarily __________________

5. Describe the arrangement of thick and thin in a sarcomere (Which is

connected to the Z-line; which is in the middle?).
