TOPIC 1: FUNCTIONS OF MUSCLE TISSUE
24 Questions • 17.1% of Exam • Explores the various roles and characteristics of different muscle types.
QUESTION 1
Which is not a function of muscle tissue?
A. Stabilizes body positions
B. Generates heat
C. Produces body movements
D. Fights off infection
Answer: D. Fights off infection.
Rationale: Muscle tissue is responsible for producing body movements, stabilizing body positions, and generating heat, as
it is the primary site for muscle contraction and relaxation. Fighting off infection, on the other hand, is a function of the
immune system, which is a separate tissue type that consists of white blood cells, lymphoid organs, and other
immune-related structures.
QUESTION 2
What are the types of striated muscle?
A. Cardiac and smooth
B. Skeletal and cardiac
C. Smooth only
D. Skeletal and smooth
Answer: B. Skeletal and cardiac.
Rationale: Striated muscles, such as skeletal and cardiac muscles, are characterized by the presence of striations or bands
of actin and myosin filaments within their cells. Since cardiac muscle is a type of striated muscle, it is only logical to include it
alongside skeletal muscle as one of the two correct types of striated muscle.

QUESTION 3
Smooth muscle is responsible for what movements?
A. Contraction of the heart
B. Stretching the arm
C. Moving food with the small intestine
D. Moving the neck to see on the right side
Answer: C. Moving food with the small intestine.
Rationale: Smooth muscle is responsible for moving food with the small intestine because the small intestine is lined with
smooth muscle that contracts and relaxes in a peristaltic manner to propel food through the digestive system. This
movement is essential for the proper digestion and absorption of nutrients, and it is a characteristic function of smooth
muscle, which is found in the walls of hollow organs and blood vessels.
QUESTION 4
Which property means the ability of muscular tissue to stretch, within limits, and not be
damaged?
A. Contractility
B. Hyperplasia
C. Elasticity
D. Extensibility
Answer: D. Extensibility.
Rationale: Muscular tissue's ability to stretch within limits without being damaged is a result of its extensibility, which allows
it to absorb and distribute forces without compromising its structural integrity. In contrast, the other options refer to
properties related to muscle contraction, growth, or the ability to return to its original shape, none of which directly address
the capacity for stretching.

QUESTION 5
Which function of muscle is best described as helping to maintain posture and
preventing unwanted movements?
A. Mobilizing substances within the body
B. Stabilizing body positions
C. Generating heat
D. Storing glucose
Answer: B. Stabilizing body positions.
Rationale: Muscles maintain posture and prevent unwanted movements by stabilizing body positions, ensuring that the
body remains in a stable and balanced state. This is achieved through the contraction of muscles that surround joints, which
helps to counteract the forces of gravity and maintain proper alignment, thereby maintaining posture and preventing
unnecessary movements.
QUESTION 6
Which is a function of skeletal muscle?
A. Moves bones and the skin of the face
B. Moves blood in blood vessels
C. Pumps blood from the heart into the blood vessels
D. Moves substances within a tube (example: peristalsis)
Answer: A. Moves bones and the skin of the face.
Rationale: Skeletal muscles are responsible for moving the skeleton and facial tissues, as they are attached to bones and
enable movements such as smiling, frowning, and blinking. The correct answer, A. Moves bones and the skin of the face,
accurately describes the primary function of skeletal muscles, which is to facilitate voluntary movements of the body's
skeleton and facial structures.
