Importance of Solving Locomotion and Movement NEET Questions 2025
This chapter helps students understand the biomechanics of the body, which is crucial for answering questions on muscle structure, the functioning of joints, and the skeletal system. NEET often tests knowledge on muscle contraction mechanisms like the sliding filament theory, types of movements, and various muscle types (skeletal, smooth, and cardiac). Additionally, questions related to disorders like arthritis or osteoporosis are frequent. By practicing NEET questions, students can sharpen their problem-solving skills, retain key physiological processes, and increase their speed and accuracy in handling conceptual and application-based queries. Ultimately, thorough practice ensures clarity on vital topics, enhances confidence, and boosts performance in the competitive exam.

Locomotion and Movement NEET Biology Questions with Explanations
Q1. The absence of relaxation between consecutive stimuli during prolonged muscle contractions is termed as:
a) Muscle fatigue
b) Muscle spasm
c) Muscle tetanus
d) Muscle tonus
Answer: c) Muscle tetanus
Explanation: Muscle tetanus is a state of constant muscle contraction due to repetitive nerve stimulation, preventing muscle relaxation between the stimuli, eventually leading to muscle fatigue.
Q2. The motor neuron connects with a muscle fiber at the:
a) Transverse tubules
b) Myofibrils
c) Neuromuscular junction
d) Sarcoplasmic reticulum
Answer: c) Neuromuscular junction
Explanation: A motor neuron interfaces with a muscle fiber at the neuromuscular junction, where it sends signals through neurotransmitters to trigger muscle contractions.
Q3. The most prominent sesamoid bone in the human body is:
a) Femur
b) Ulna
c) Patella
d) Pelvis
Answer: c) Patella
Explanation: The patella, also known as the kneecap, is the most significant sesamoid bone in humans, situated between the femur and tibia, playing a crucial role in joint stability and mobility.
Q4. The only movable bone in the human skull is the:
a) Nasal conchae
b) Vomer
c) Mandible
d) Maxilla
Answer: c) Mandible
Explanation: The mandible, or lower jawbone, is the only movable bone in the skull. It connects to the skull through the temporomandibular joint, allowing movements required for speaking, chewing, and facial expressions.
Q5. Skeletal muscle fibers are bundled and encased in a connective tissue layer called:
a) Fascia
b) Perimysium
c) Endomysium
d) Aponeurosis
Answer: b) Perimysium
Explanation: The perimysium is a connective tissue layer that surrounds bundles of skeletal muscle fibers (fascicles). It provides support and facilitates the transmission of nerve signals and blood supply within the muscle.
Q6. Which of the following pairs of antagonistic muscles is incorrectly matched?
a) Abductor – Adductor
b) Levator – Depressor
c) Pronator – Supinator
d) Flexor – Relaxor
Answer: d) Flexor – Relaxor
Explanation: The correct antagonistic muscle pair for flexors is extensors, not relaxors. Flexors cause bending of a joint, while extensors straighten it.
Q7. Which of the following statements is true regarding a specific musculoskeletal disorder?
a) Gout is caused by calcium deposition in joints.
b) Muscular dystrophy is an age-related muscle shortening.
c) Osteoporosis leads to reduced bone mass and increased fracture risk.
d) Myasthenia gravis affects the sliding of myosin filaments.
Answer: c) Osteoporosis leads to reduced bone mass and increased fracture risk.
Explanation: Osteoporosis is a condition that reduces bone density, making bones fragile and more susceptible to fractures. Gout is caused by uric acid buildup, and muscular dystrophy is a genetic disorder, not age-related. Myasthenia gravis affects neuromuscular transmission rather than myosin filament sliding.
Q8. Choose the correct statement regarding human skeletal anatomy:
a) The first vertebra, the atlas, articulates with the occipital condyles.
b) The 9th and 10th ribs are referred to as floating ribs.
c) The glenoid cavity articulates with the femur.
d) The parietal and temporal bones of the skull are joined by a cartilaginous joint.
Answer: a) The first vertebra, the atlas, articulates with the occipital condyles.
Explanation: The atlas is the first cervical vertebra that connects with the occipital condyles of the skull, enabling head movement. The 11th and 12th ribs are called floating ribs, and the glenoid cavity connects to the humerus, not the femur.
Q9. During muscle contraction, which of the following lengths remains unchanged?
a) H-zone
b) Sarcomere
c) I-band
d) A-band
Answer: d) A-band
Explanation: The A-band, representing the length of thick filaments, remains constant during muscle contraction, while other regions like the H-zone and I-band decrease as the sarcomere shortens.
