Muscle Tissue Types (30 Questions)
QUESTION 1: How many types of muscle tissue are found in the human body?
Answer: Three
Rationale: The human body has three muscle tissue types: skeletal, cardiac, and smooth ().
QUESTION 2: Which muscle tissue is under voluntary control?
Answer: Skeletal
Rationale: Skeletal muscle allows conscious control, unlike involuntary cardiac and smooth
muscles ().
QUESTION 3: Where is cardiac muscle primarily located?
Answer: Heart
Rationale: Cardiac muscle is exclusive to the heart, enabling its pumping action ().
QUESTION 4: Which muscle tissue type has intercalated discs?
Answer: Cardiac
Rationale: Intercalated discs are unique to cardiac muscle, facilitating synchronized contractions
().
QUESTION 5 (Scenario-Based): A patient can flex their arm to lift a weight but cannot control
their heart rate. Which muscle types are involved?
Answer: Skeletal and cardiac
Rationale: Arm flexion involves skeletal muscle (voluntary), while heart rate is controlled by
cardiac muscle (involuntary) ().
,QUESTION 6 (Select All That Apply): Which characteristics describe smooth muscle? Select
all that apply: Involuntary control, Striated appearance, Found in blood vessel walls,
Multinucleated cells, Spindle-shaped cells.
Answer: Involuntary control, Found in blood vessel walls, Spindle-shaped cells
Rationale: Smooth muscle is involuntary, found in vessel walls, and has spindle-shaped cells.
Striations and multinucleation are specific to skeletal muscle ().
QUESTION 7: Which muscle tissue is multinucleated?
Answer: Skeletal
Rationale: Skeletal muscle cells have multiple nuclei due to their large size and fusion during
development ().
QUESTION 8: What is a key feature of cardiac muscle cells?
Answer: Branched fibers
Rationale: Cardiac muscle has branched fibers for coordinated contractions, unlike skeletal or
smooth muscle ().
QUESTION 9 (Scenario-Based): A patient with a digestive disorder shows impaired peristalsis.
Which muscle type is likely affected?
Answer: Smooth
Rationale: Smooth muscle drives peristalsis in the digestive tract ().
QUESTION 10: Which muscle tissue type lacks striations?
Answer: Smooth
Rationale: Smooth muscle lacks striations, unlike skeletal and cardiac muscle ().
QUESTION 11: Where is smooth muscle primarily found?
Answer: Blood vessels and organs
Rationale: Smooth muscle lines blood vessels, digestive organs, and other internal structures ().
QUESTION 12 (Select All That Apply): Which features are true of skeletal muscle? Select all
that apply: Voluntary control, Multinucleated cells, Found in the heart, Striated appearance,
Contracts slowly.
Answer: Voluntary control, Multinucleated cells, Striated appearance
, Rationale: Skeletal muscle is voluntary, multinucleated, and striated. It is not in the heart, and it
contracts rapidly ().
QUESTION 13: What is the primary function of skeletal muscle?
Answer: Move bones
Rationale: Skeletal muscle attaches to bones to facilitate movement ().
QUESTION 14 (Scenario-Based): A patient cannot maintain blood pressure due to weak vessel
walls. Which muscle type is involved?
Answer: Smooth
Rationale: Smooth muscle in blood vessel walls regulates blood pressure ().
QUESTION 15: Which muscle type is responsible for involuntary contractions in the digestive
system?
Answer: Smooth
Rationale: Smooth muscle drives involuntary movements like peristalsis ().
QUESTION 16: What feature allows cardiac muscle cells to contract synchronously?
Answer: Intercalated discs
Rationale: Intercalated discs connect cardiac muscle cells, enabling coordinated contractions ().
QUESTION 17: Which muscle type contracts most rapidly?
Answer: Skeletal
Rationale: Skeletal muscle contracts rapidly for quick movements, unlike slower cardiac and
smooth muscles ().
QUESTION 18 (Select All That Apply): Which are true of cardiac muscle? Select all that
apply: Found in the heart, Involuntary control, Striated appearance, Multinucleated cells,
Branched fibers.
Answer: Found in the heart, Involuntary control, Striated appearance, Branched fibers
Rationale: Cardiac muscle is in the heart, involuntary, striated, and branched. It is not
multinucleated ().
