Exam Bank for Muscular System- Latest Update 2025 (Already Passed)
What are the three muscle types in the body? - Answers skeletal, cardiac, smooth
What is the endomysium? - Answers a thin layer of connective tissue that surrounds each muscle fiber
What is the perimysium? - Answers connective tissue that surrounds groups of 10-100 individual muscle
fibers separating them into bundles called fascicles.
What is the epimysium? - Answers Connective tissue layer(outside muscle); an overcoat of dense
irregular connective tissue that surrounds the whole muscle
Where are smooth muscles found in the body? - Answers walls of hollow organs (except heart) in the
digestive system, blood vessels, and urinary system
How is cardiac muscle contraction regulated? - Answers involuntary contraction
What are the functions of muscle? - Answers producing movement, maintaining posture, stabilizing
joints and generating heat
What is the sarcolemma? - Answers specialized plasma membrane of muscle cells
What is the function of the sarcoplasmic reticulum? - Answers stores calcium
What is myosin? - Answers Thick filament protein with a head and elongated tail, the heads form cross
bridges with the thin filaments during muscle contraction
What is actin? - Answers Thin filament protein. Twisted into a double helix and appears like a double-
stranded chain of pearls. Contains the myosin-binding site.
What is the neurotransmitter for muscle contraction? - Answers acetylcholine (ACh)
What is the energy needed for muscle contraction? - Answers stored ATP
What types of muscles are involuntary? - Answers smooth and cardiac
What types of muscle are striated? - Answers skeletal and cardiac
What type of muscle is voluntary? - Answers skeletal
What type of muscle has intercalated discs? - Answers cardiac
Where is glycogen stored in the muscle cells? - Answers in glycosomes
What is the cytoplasm of the muscle cell? - Answers sarcoplasm
What is the light area of the sarcomere? - Answers I Band
What structure attaches a bone to a muscle? - Answers tendon
