  1. Question 1 · NEET 2026 · Q142 · +4 / −1

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

    Answer and explanation

    Answer: (4)

    At a chemical synapse, the neurotransmitter is released from the pre-synaptic neuron into the synaptic cleft and binds to specific receptors located on the post-synaptic membrane, opening ion channels and generating a new potential. Therefore the neurotransmitter receptors are present on the post-synaptic membrane, not on the pre-synaptic membrane, Schwann cell, or myelin sheath.

  2. Question 2 · Re-NEET 2026 · Q95 · +4 / −1

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

    Answer and explanation

    Answer: (4)

    The pericardium is the double-walled sac enclosing the HEART and belongs to the circulatory system. The other three are the meninges - the tough outer dura mater, the web-like middle arachnoid and the delicate inner pia mater - which wrap the brain and spinal cord.

  3. Question 3 · NEET 2020 · Q70 · +4 / −1

    Match the following columns and select the correct option.

    List I

    List II

    P) Organ of Corti

    I) Connects middle ear and pharynx

    Q) Cochlea

    II) Coiled part of the labyrinth

    R) Eustachian tube

    III) Attached to the oval window

    S) Stapes

    IV) Located on the basilar membrane

    Answer and explanation

    Answer: (2)

    The organ of Corti lies on the basilar membrane; the cochlea is the coiled labyrinth; the Eustachian tube joins the middle ear to the pharynx; and the stapes contacts the oval window. Thus P-IV, Q-II, R-I, S-III. Chapter: Neural Control and Coordination.
