Show answer & explanation
Correct answer: C — Voluntary movement
Voluntary movement is initiated consciously by the nervous system, whereas involuntary movement is automatic and unconscious.
Q2. Movement that occurs in the sagittal plane involves which type of joint action primarily?
Show answer & explanation
Correct answer: A — Flexion and Extension
Flexion and extension movements, where the body moves forward and backward, occur primarily in the sagittal plane.
Q3. In the context of muscle mechanics, which factor primarily determines the type of mechanical action (e.g., pulling, pushing, rotating) performed by a muscle?
Show answer & explanation
Correct answer: A — Mechanical advantage of the lever system
The mechanical advantage provided by the bone-muscle system and the attachment points (lever system) dictates the type of mechanical action the muscle produces.
Q4. Which tissue is characterized by the presence of striations and is responsible for voluntary movements?
Show answer & explanation
Correct answer: B — Skeletal muscle
Skeletal muscle tissue is striated and is the type of muscle tissue attached to bones, controlling voluntary movements.
Q5. The rhythmic, involuntary contraction and relaxation characteristic of the heart is a specific type of movement exhibited by which type of muscle?
Show answer & explanation
Correct answer: C — Cardiac muscle
Cardiac muscle tissue is found only in the heart and exhibits rhythmic, involuntary contractions.
Q6. The specialized junction between two adjacent muscle fibers that allows for coordinated contraction is known as the:
Show answer & explanation
Correct answer: C — Neuromuscular junction
The neuromuscular junction is the specialized site where a motor neuron communicates with a muscle fiber, initiating contraction.
Q7. What is the functional unit of the muscle that generates force?
Show answer & explanation
Correct answer: C — Sarcomere
The sarcomere is the smallest functional unit of a muscle, defined as the region between two successive Z-discs, which is the basic unit of contractile force generation.
Q8. The functional unit of a muscle fiber, which is the basic contractile element, is called the:
Show answer & explanation
Correct answer: C — Sarcomere
The sarcomere is the basic contractile unit of striated muscle, bounded by Z-discs, and is the fundamental unit upon which muscle contraction occurs.
Q9. Movement that occurs when a muscle generates tension without a change in its length is known as:
Show answer & explanation
Correct answer: D — Isometric movement
Isometric movement is the contraction of a muscle where tension is generated but the muscle length does not change.
Q10. Which type of joint allows for the greatest range of motion, enabling movements in three planes (flexion, extension, rotation)?
Show answer & explanation
Correct answer: A — Ball and Socket joint
Ball and Socket joints (like the shoulder and hip) are synovial joints that permit movement in multiple planes, offering the greatest range of motion compared to hinge or pivot joints.
Q11. When a muscle contracts, the fundamental process involves the sliding of thick and thin filaments. Which of the following accurately describes the outcome of this sliding action in muscle tissue?
Show answer & explanation
Correct answer: B — The Z-lines move closer together, causing the sarcomere to shorten
Muscle contraction occurs due to the sliding filament mechanism, where the thin filaments slide past the thick filaments. This sliding action causes the sarcomere (the basic contractile unit) to shorten, which results in the overall shortening of the muscle fiber.
Q12. Which of the following planes of movement allows rotation of the body around a longitudinal axis, such as twisting the torso?
Show answer & explanation
Correct answer: C — Transverse plane
The transverse plane is defined by movements that occur around the transverse axis, which includes rotational movements like twisting the torso. The sagittal plane primarily involves flexion/extension, and the coronal plane involves adduction/abduction.
Q13. Which type of muscle tissue is characterized by the presence of striations and is responsible for voluntary movements of the skeleton?
Show answer & explanation
Correct answer: A — Skeletal muscle
Skeletal muscles are striated and are under voluntary control, allowing for body movement.
Q14. In muscle physiology, the arrangement of actin and myosin filaments within the sarcomere dictates the structure of the muscle fiber. This functional unit is known as:
Show answer & explanation
Correct answer: C — Sarcomere
The sarcomere is the basic functional unit of a muscle fiber, defined by the arrangement of overlapping actin and myosin filaments.
