Locomotion and Movement

Q. What is the function of ligaments in the body?

Solution

Ligaments connect bones to other bones, providing stability to joints.

Correct Answer: B — To connect bones to bones

Q. What is the primary energy source for muscle contraction?

Solution

Glucose is the primary energy source for muscle contraction, providing ATP through cellular respiration.

Correct Answer: A — Glucose

Q. What is the primary function of the skeletal system in locomotion?

Solution

The skeletal system provides structure and support, allowing for movement and locomotion.

Correct Answer: C — To provide structure and support

Q. What is the primary role of the neuromuscular junction?

Solution

The neuromuscular junction transmits signals from nerves to muscles, initiating muscle contraction.

Correct Answer: B — To transmit signals from nerves to muscles

Q. What is the role of tendons in the muscular system?

Solution

Tendons connect muscles to bones, facilitating movement when muscles contract.

Correct Answer: A — To connect muscles to bones

Q. Which muscle type is responsible for voluntary movements?

Solution

Skeletal muscle is responsible for voluntary movements, allowing for conscious control of locomotion.

Correct Answer: C — Skeletal muscle

Q. Which part of the brain is primarily responsible for coordinating movement?

Solution

The cerebellum coordinates voluntary movements and maintains balance and posture.

Correct Answer: B — Cerebellum

Q. Which structure in the muscle fibers stores calcium ions necessary for contraction?

Solution

The sarcoplasmic reticulum stores calcium ions, which are released during muscle contraction.

Correct Answer: C — Sarcoplasmic reticulum

Q. Which type of muscle is found in the walls of the heart?

Solution
