1. Question 1 (NEET 2026)

   NEET 2026EasyMeninges of the human brain

   Which of the following is not a part of human central neural system?

   1. AOption A: Arachnoid
   2. BOption B: Dura mater
   3. COption C: Pia mater
   4. DOption D: Pericardium

   Show answer & explanationHide answer & explanation

   Correct answer: (D) Pericardium

   Explanation

   The human brain is protected by three cranial meninges: an outer dura mater, a very thin middle arachnoid and an inner pia mater, which is in contact with the brain tissue. These are coverings of the central neural system. The pericardium is the double-walled membranous bag that encloses the heart, so it is not a part of the central neural system. Hence the answer is option (D).

2. Question 2 (NEET 2026)

   NEET 2026EasyNerve Impulse

   The specific receptors for neurotransmitters in a synapse are present on ________.

   1. AOption A: Schwann cell
   2. BOption B: Pre-synaptic membrane
   3. COption C: Myelin sheath
   4. DOption D: Post-synaptic membrane

   Show answer & explanationHide answer & explanation

   Correct answer: (D) Post-synaptic membrane

   Explanation

   Neurotransmitter receptors are located on the post-synaptic membrane, where they receive chemical signals from the synaptic cleft.

3. Question 3 (NEET 2024)

   NEET 2024MediumCentral Nervous System

   Match List I with List II : Choose the correct answer from the options given below :

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

   Show answer & explanationHide answer & explanation

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

   Explanation

   Pons acts as a bridge connecting different regions of the brain. Hypothalamus contains neurosecretory cells. Medulla controls respiration and gastric secretions. Cerebellum provides additional space for neurons and regulates posture and balance. Hence the correct match is A-III, B-IV, C-II, D-I.

4. Question 4 (NEET 2024)

   NEET 2024EasyCentral Nervous System

   Given below are two statements : Statement I : The cerebral hemispheres are connected by nerve tract known as corpus callosum. Statement II : The brain stem consists of the medulla oblongata, pons and cerebrum. In the light of the above statements, choose the most appropriate answer from the options given below :

   1. AOption A: Statement I is correct but Statement II is incorrect.
   2. BOption B: Statement I is incorrect but Statement II is correct.
   3. COption C: Both Statement I and Statement II are correct.
   4. DOption D: Both Statement I and Statement II are incorrect.

   Show answer & explanationHide answer & explanation

   Correct answer: (A) Statement I is correct but Statement II is incorrect.

   Explanation

   The two cerebral hemispheres are connected by the corpus callosum. However, the brain stem consists of the midbrain, pons, and medulla oblongata, not the cerebrum. Hence Statement I is correct and Statement II is incorrect.

   Show answer & explanationHide answer & explanation

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

   Explanation

   Fovea is the point of greatest visual acuity. Iris is the coloured portion regulating pupil diameter. Blind spot is the point where the optic nerve exits and photoreceptors are absent. Sclera is the outer dense connective tissue layer.

6. Question 6 (NEET 2023)

   NEET 2023EasyNervous System

   The parts of human brain that helps in regulation of sexual behaviour, expression of excitement, pleasure, rage, fear etc. are :

   1. AOption A: Limbic system & hypothalamus
   2. BOption B: Corpora quadrigemina & hippocampus
   3. COption C: Brain stem & epithalamus
   4. DOption D: Corpus callosum and thalamus

   Show answer & explanationHide answer & explanation

   Correct answer: (A) Limbic system & hypothalamus

   Explanation

   The limbic system along with hypothalamus regulates emotional reactions, sexual behaviour, pleasure, rage and fear.

7. Question 7 (NEET 2022)

   NEET 2022MediumNerve Impulse

   Select the incorrect statement regarding synapses:

   1. AOption A: Impulse transmission across a chemical synapse is always faster than that across an electrical synapse
   2. BOption B: The membranes of presynaptic and postsynaptic neurons are in close proximity in an electrical synapse
   3. COption C: Electrical current can flow directly from one neuron into the other across the electrical synapse
   4. DOption D: Chemical synapses use neurotransmitters

   Show answer & explanationHide answer & explanation

   Correct answer: (A) Impulse transmission across a chemical synapse is always faster than that across an electrical synapse

   Explanation

   Electrical synapses are faster because ions pass directly between cells. Chemical synapses involve neurotransmitter release and synaptic delay.

   Show answer & explanationHide answer & explanation

   Correct answer: (B) Inflammation of cornea due to high dose of UV-B radiation

   Explanation

   Snow blindness is caused by inflammation of the cornea due to excessive exposure to ultraviolet-B radiation reflected from snow.

10. Question 10 (NEET 2019)

    NEET 2019MediumNervous System

    Which of the following statements is not correct?

    1. AOption A: In the knee-jerk reflex, stimulus is the stretching of muscle and response is its contraction
    2. BOption B: An action potential in an axon does not move backward because the segment behind is in a refractory phase
    3. COption C: Depolarisation of hair cells of cochlea results in the opening of the mechanically gated potassium-ion channels
    4. DOption D: Rods are very sensitive and contribute to daylight vision

    Show answer & explanationHide answer & explanation

    Correct answer: (D) Rods are very sensitive and contribute to daylight vision

    Explanation

    Rods are highly sensitive photoreceptor cells that function mainly in dim light (scotopic vision), whereas cones are responsible for daylight and colour vision. Therefore, the statement that rods contribute to daylight vision is incorrect. The other statements are correct: - Knee-jerk reflex is initiated by stretching of muscle followed by contraction. - Backward movement of action potential is prevented due to the refractory phase. - In cochlear hair cells, depolarisation occurs due to opening of mechanically gated K+ channels.
