What are anabolic steroids prescribed for?
diseases in which muscle atrophy occurs, hormonal imbalances
200
Hollow channel in bone in which blood vessels pass.
What is Haversian canals.

What do actin and myosin do?
They facilitate muscle contraction inside the sarcomere. The myosin head binds to actin pulling the filaments closer together, contracting the sarcomere and thus the muscle.
