03_Muscle Overview

What is the functional unit of contraction for a muscle?

• fascicle

• fiber

• myofibril

• sarcomere

What fiber arrangement allows force to be produced at faster motions?

• parallel

• unipennate

• bipennate

• multipennate

The Sliding Filament Theory indicates _______ is responsible for force generation due from the myosin head pivoting and shortening the sarcomere.

• titin

• cross-bridge formation

• the power stroke

• the parallel elastic component

What type of muscle action occurs when the external torque is greater than the internal torque?

• isometric

• concentric

• eccentric

• isokinetic

According the the Hill Muscle Model, the _______ is from actin and myosin producing active tension.

• contractile component

• parallel elastic component

• series elastic component

• perpendicular elastic component
