NEET 2025 MCQ with Answer Explanation : “Locomotion and Movement”.

Here below some basic MCQ’s of “Locomotion and Movement” with answer which is explained in details. Let’s check one by one which is given below.

MCQ 1
Which type of muscle is responsible for voluntary movement in the body?

A) Smooth
B) Cardiac
C) Skeletal
D) Involuntary

Answer: C) Skeletal

Explanation: Skeletal muscles are under voluntary control, allowing for conscious movement, such as walking or lifting objects.

MCQ 2
What is the primary function of the sarcomere in muscle contraction?

A) Store calcium
B) Generate action potentials
C) Contract and relax
D) Produce energy

Answer: C) Contract and relax

 
Explanation: Sarcomeres are the basic contractile units of muscle fibers, where the sliding filament mechanism occurs, allowing muscles to contract and relax.

MCQ 3
Which structure acts as a lever in the human body during movement?

A) Muscle
B) Joint
C) Bone
D) All of the above

Answer: D) All of the above

 
Explanation: Muscles pull on bones (levers) at joints to create movement; thus, all these structures contribute to locomotion.

MCQ 4
Which of the following best describes the role of tendons?

A) Connect muscle to muscle
B) Connect muscle to bone
C) Provide blood supply to muscles
D) Store energy for muscle contraction

Answer: B) Connect muscle to bone

Explanation: Tendons are fibrous connective tissues that attach muscles to bones, enabling the transfer of force during movement.

MCQ 5
What type of joint allows for the widest range of motion?

A) Hinge joint
B) Ball-and-socket joint
C) Pivot joint
D) Saddle joint

Answer: B) Ball-and-socket joint
Explanation: Ball-and-socket joints, such as the shoulder and hip joints, allow for rotational and multidirectional movement.

MCQ 6
Which of the following is NOT a type of locomotion?

A) Walking
B) Swimming
C) Jumping
D) Breathing

Answer: D) Breathing
Explanation: Breathing is a vital process for respiration, not a mode of locomotion, which involves moving from one place to another.

MCQ 7
What is the role of calcium ions in muscle contraction?

A) They energize muscle fibers.
B) They facilitate the binding of actin and myosin.
C) They increase muscle temperature.
D) They prevent muscle fatigue.

Answer: B) They facilitate the binding of actin and myosin.
Explanation: Calcium ions bind to troponin, causing a conformational change that allows myosin to bind to actin, initiating contraction.

MCQ 8
Which protein is primarily responsible for muscle contraction?

A) Actin
B) Myosin
C) Troponin
D) Tropomyosin

Answer: B) Myosin
Explanation: Myosin is the thick filament in muscle fibers that interacts with actin to generate force during contraction.

MCQ 9
What type of locomotion do earthworms primarily use?

A) Swimming
B) Walking
C) Slithering
D) Peristalsis

Answer: D) Peristalsis
Explanation: Earthworms use peristaltic movements, contracting and relaxing their muscles in waves to move through soil.

MCQ 10
What is the primary energy source for muscle contraction?

A) Fatty acids
B) Glucose
C) ATP
D) Proteins

Answer: C) ATP
Explanation: Adenosine triphosphate (ATP) provides the energy required for muscle contraction and relaxation.
