Match List I with List II regarding synapses. List I List II (A) Fluid-filled space called synaptic cleft (I) Electrical synapse (B) Membranes are in very close proximity (II) Chemical synapse (C) Slower impulse transmission (D) Rare in our system Choose the correct answer from the options given below:

Options

  1. A(A)-(I), (B)-(II), (C)-(I), (D)-(II)
  2. B(A)-(II), (B)-(I), (C)-(I), (D)-(II)
  3. C(A)-(II), (B)-(I), (C)-(II), (D)-(I)
  4. D(A)-(I), (B)-(II), (C)-(II), (D)-(I)

Correct answer

C. (A)-(II), (B)-(I), (C)-(II), (D)-(I)

Step-by-step solution

At a chemical synapse, the membranes of the pre- and post-synaptic neurons are separated by a fluid-filled space called the synaptic cleft. Impulse transmission across a chemical synapse is slower compared to an electrical synapse. At electrical synapses, the membranes of pre- and post-synaptic neurons are in very close proximity, allowing direct flow of electrical current, making transmission faster. Electrical synapses are rare in the human neural system. Therefore, the correct matching is (A)-(II), (B)-(I), (C)-
