1. Question 1 (NEET 2026)

   NEET 2026EasyAxial skeleton: vertebral column

   The number of vertebrae in a human is ________.

   1. AOption A: 7
   2. BOption B: 12
   3. COption C: 26
   4. DOption D: 206

   Show answer & explanationHide answer & explanation

   Correct answer: (C) 26

   Explanation

   According to NCERT, the human vertebral column is formed by 26 serially arranged units called vertebrae. They are 7 cervical, 12 thoracic, 5 lumbar, 1 sacral (fused) and 1 coccygeal (fused) vertebrae: $7 + 12 + 5 + 1 + 1 = 26$. The distractors are other well-known numbers: 7 is the number of cervical vertebrae, 12 the number of thoracic vertebrae (and pairs of ribs), and 206 the total number of bones in the adult human skeleton. So the answer is option (C).

2. Question 2 (NEET 2026)

   NEET 2026EasyAppendicular skeleton: bones of hind limb

   Which of the following represents the correct sequence of arrangement of bones in the lower limb of humans?

   1. AOption A: Femur-tibia-patella-tarsal
   2. BOption B: Patella-femur-tibia-tarsal
   3. COption C: Femur-patella-tibia-tarsal
   4. DOption D: Femur-tarsal-patella-tibia

   Show answer & explanationHide answer & explanation

   Correct answer: (C) Femur-patella-tibia-tarsal

   Explanation

   Each human hind limb consists of femur (thigh bone, the longest bone of the body), tibia and fibula, tarsals (ankle bones), metatarsals and phalanges. The femur is the uppermost bone. A cup-shaped bone called the patella covers the knee ventrally, i.e. it lies at the knee joint between the femur and the tibia. Below the knee are the tibia (and fibula), followed by the tarsals at the ankle. So from top to bottom the order is femur → patella → tibia → tarsal, which is option (C).

3. Question 3 (NEET 2026)

   NEET 2026EasyTypes of movement

   Sperm motility is due to ___________.

   1. AOption A: flagellar movement
   2. BOption B: ciliary movement
   3. COption C: amoeboid movement
   4. DOption D: muscular movement

   Show answer & explanationHide answer & explanation

   Correct answer: (A) flagellar movement

   Explanation

   Cells of the human body show three main types of movement: amoeboid, ciliary and muscular, plus flagellar movement. Flagellar movement helps in the swimming of spermatozoa (and in maintaining water current in sponges and locomotion of protists like Euglena). The sperm tail is a flagellum that facilitates sperm motility, which is essential for fertilisation. Ciliary movement occurs in the trachea and fallopian tubes, amoeboid movement in macrophages and leucocytes, and muscular movement in limbs and jaws. So sperm motility is due to flagellar movement, option (A).

4. Question 4 (NEET 2026)

   NEET 2026MediumFrog - Sexual Dimorphism

   Male frogs can be distinguished from female frogs due to the presence of: A. Bulging eyes B. Vocal sacs C. Webbed digits in feet D. Copulatory pad on first digit of fore limbs E. Olive green-coloured skin with dark irregular spots Choose the correct answer from the options given below

   1. AOption A: B and C only
   2. BOption B: C and E only
   3. COption C: A and B only
   4. DOption D: B and D only

   Show answer & explanationHide answer & explanation

   Correct answer: (D) B and D only

   Explanation

   Male frogs possess vocal sacs and copulatory (nuptial) pads on the first digit of forelimbs, which help during mating.

5. Question 5 (NEET 2026)

   NEET 2026EasyMechanism of muscle contraction

   Muscle contraction is initiated by a signal sent by the central nervous system by the release of _____ .

   1. AOption A: acetyl choline
   2. BOption B: acetyl coenzyme A
   3. COption C: cyclic guanine monophosphate
   4. DOption D: cyclic adenine monophosphate

   Show answer & explanationHide answer & explanation

   Correct answer: (A) acetyl choline

   Explanation

   Muscle contraction is initiated by a signal sent by the central nervous system via a motor neuron. A neural signal reaching the neuromuscular junction (motor end plate) releases a neurotransmitter, acetyl choline, which generates an action potential in the sarcolemma. This spreads through the muscle fibre and causes release of calcium ions into the sarcoplasm, leading to cross-bridge formation and sliding of filaments. Acetyl coenzyme A is a respiratory intermediate, and cGMP/cAMP are intracellular second messengers. Hence option (A).

6. Question 6 (NEET 2026)

   NEET 2026EasyVertebral column (axial skeleton)

   Which of the following is the correct order of arrangement of vertebrate column from the head to toe?

   1. AOption A: Cervical vertebra, thoracic vertebra, sacrum, lumbar vertebra
   2. BOption B: Sacrum, lumbar vertebra, thoracic vertebra, cervical vertebra
   3. COption C: Cervical vertebra, lumbar vertebra, thoracic vertebra, sacrum
   4. DOption D: Cervical vertebra, thoracic vertebra, lumbar vertebra, sacrum

   Show answer & explanationHide answer & explanation

   Correct answer: (D) Cervical vertebra, thoracic vertebra, lumbar vertebra, sacrum

   Explanation

   The human vertebral column is formed by 26 serially arranged vertebrae. From the skull downwards they are: cervical (7), thoracic (12), lumbar (5), sacral (1, fused) and coccygeal (1, fused). So the order from head to toe is cervical → thoracic → lumbar → sacrum. Hence option (D).

7. Question 7 (NEET 2026)

   NEET 2026MediumMuscle Structure and Contraction

   Choose the correct statements regarding muscle contraction: A. A motor neuron carries a signal sent by the Central Nervous System (CNS) to the sarcolemma of the muscle fibre. B. The neural signal generates an action potential which causes the release of Ca⁺⁺ into sarcoplasm. C. Increase in Ca⁺⁺ inactivates the actin for breaking cross bridges. D. Actin binds to the myosin head to form a cross bridge. E. Shortening of sarcomere takes place, by pulling actin filaments towards the centre of 'A' band. Choose the correct answer from the options given below :

   1. AOption A: C and D only
   2. BOption B: A and B only
   3. COption C: C and E only
   4. DOption D: A, B, D and E only

   Show answer & explanationHide answer & explanation

   Correct answer: (D) A, B, D and E only

   Explanation

   Motor neuron signals trigger Ca²⁺ release, enabling actin-myosin cross-bridge formation and sliding of actin filaments toward the centre of the A band. Statement C is incorrect because Ca²⁺ binds troponin rather than directly activating actin to break cross bridges.

8. Question 8 (NEET 2026)

   NEET 2026MediumSkeletal System

   Which of the following statements are correct with reference to human endoskeleton? A. Human skull is monocondylic. B. The joint between any two adjoining vertebrae is a cartilaginous joint. C. In human beings, the number of cervical vertebrae is seven. D. All ribs except the last 2 pairs are bicephalic. E. The occipital bone of skull is articulated with atlas vertebra. Choose the correct answer from the options given below:

   1. AOption A: B and E only
   2. BOption B: B, C and E only
   3. COption C: C, D and E only
   4. DOption D: A, B and D only

   Show answer & explanationHide answer & explanation

   Correct answer: (B) B, C and E only

   Explanation

   Humans have 7 cervical vertebrae. Adjacent vertebrae are connected by cartilaginous joints, and the occipital bone articulates with the atlas. Human skull is dicondylic, and all ribs except the last two pairs are bicephalic.

9. Question 9 (NEET 2026)

   NEET 2026MediumMusculoskeletal Disorders

   Match List I with List II related to muscular/skeletal system: Choose the correct answer from the options given below:

   3. COption C: A-IV, B-III, C-II, D-I
   4. DOption D: A-III, B-II, C-I, D-IV

   Show answer & explanationHide answer & explanation

   Correct answer: (A) A-III, B-I, C-II, D-IV

   Explanation

   Tetany is caused by low Ca²⁺ leading to muscle spasms; arthritis is inflammation of joints; myasthenia gravis is an autoimmune disorder affecting neuromuscular junctions; muscular dystrophy involves progressive degeneration of skeletal muscles.
