Muscle Tissue Classification and Characteristics: Interactive Learning Quizzes

Question 1

How does the arrangement of actin and myosin filaments in skeletal muscle contribute to force generation and postural maintenance?

Accepted Answer

Actin and myosin filaments are arranged in parallel, allowing them to slide past each other during contraction, generating force.

Answer

Actin and myosin filaments are arranged perpendicularly, allowing the muscle to contract and expand.
