REAL EXAM QUESTIONS AND CORRECT VERIFIED
ANSWERS/ ALREADY GRADED A+ (MOST RECENT!!)
1. Which of the following is a primary function of muscle
tissue?
A. Vitamin storage
B. Hematopoiesis
C. Heat production
D. Hormone secretion
Correct Answer: C
Rationale: Muscle tissue generates heat as a byproduct of
contraction. Up to 75% of the energy produced by muscle tissue is
released as heat, which is essential for maintaining body
temperature .
2. How many skeletal muscle tissue functions are there?
A. 3
B. 4
1
,C. 6
D. 8
Correct Answer: C
Rationale: The six skeletal muscle tissue functions are: producing
body movement, maintaining posture and body position, supporting
soft tissues, guarding body entrances/exits, maintaining body
temperature, and storing nutrients .
3. Which functional characteristic of skeletal muscle describes
its ability to respond to a stimulus?
A. Contractility
B. Extensibility
C. Elasticity
D. Irritability (excitability)
Correct Answer: D
Rationale: Irritability, also known as excitability, is the ability of a
muscle to respond to a stimulus (such as a nerve impulse). This is the
first step in the contraction process .
4. Skeletal muscles stabilize joints as part of which function?
A. Produce body movement
B. Maintain posture and body position
2
,C. Support soft tissues
D. Guard body entrances
Correct Answer: B
Rationale: Maintaining posture and body position involves
stabilizing joints so that the body can remain upright or maintain a
specific position against gravity .
5. The ability of a muscle to shorten is called:
A. Elasticity
B. Contractility
C. Extensibility
D. Irritability
Correct Answer: B
Rationale: Contractility is the unique ability of muscle tissue to
shorten forcefully. This shortening is what produces movement when
muscles pull on bones .
6. What term describes a muscle's ability to return to its
original length after being stretched?
A. Contractility
B. Extensibility
C. Elasticity
D. Conductivity
3
, Correct Answer: C
Rationale: Elasticity is the ability of muscle tissue to recoil and
return to its resting length after being stretched. This property helps
maintain muscle shape .
7. Which function of skeletal muscle involves sphincters
encircling body openings?
A. Support soft tissues
B. Guard body entrances and exits
C. Maintain body temperature
D. Store nutrients
Correct Answer: B
Rationale: Sphincters are circular muscles that encircle openings and
provide voluntary control of swallowing, defecation, and urination,
thereby guarding body entrances and exits .
8. How do skeletal muscles contribute to maintaining body
temperature?
A. By storing fat
B. By shivering and contraction
C. By releasing hormones
D. By insulating organs
