D) Keep blood moving in veins and lymphatics

2) The contractile cells within muscle tissue are referred to as
A) fibers.
B) striations.
C) myofibrils.
D) fascicles.

3) A bundle of muscle fibers is called a
A) sarcomere.
B) fascicle.
C) myofibril.
D) synergist.

4) Which of the following surrounds a muscle fiber?

7) Skeletal muscle is highly thermogenic; that is, is produces heat. How?

C) Skeletal muscle contracts around sweat glands, producing heat.
D) When myofilaments shorten, they release heat.

8) The pressure of skeletal muscle contraction is important in maintaining blood circulation.

9) Cardiac muscle fibers need outside nervous stimulation in order to contract.

10) Which type(s) of muscle tissue has/have intercalated disks?
A) Cardiac
B) Skeletal
C) Smooth
D) Both cardiac and skeletal have intercalated discs.
