Question

Match the items of column I with those of column II.
$\begin{array}{cc}\text{Column I}& \text{Column II}\\ \text{(p) Sensory nerve}& \text{(i) passes signals from the}\\ & \text{brain or the spinal cord to the}\\ & \text{effector organs}\\ \text{(q) Motor nerve}& \text{(ii) passes impulses from the}\\ & \text{receptors to the brain or the}\\ & \text{spinal cord}\\ \text{(r) Synapse}& \text{(iii) Neurotransmitter}\\ \text{(s) Acetylcholine}& \text{(iv) point of contact between}\\ & \text{the axon of one neuron and the}\\ & \text{dendrites of another neuron}\end{array}$

• A. p – ii; q – iii; r – iv; s – i
• B. P – ii; q – i; r – iii; s – ii
• C. p – ii; q – i; r – iv; s – iii
• D. p – i; q – ii; r – iii; s – iv

Answer 1

The correct option is C p – ii; q – i; r – iv; s – iii

Sensory nerves pass impulses from the receptors to the brain or the spinal cord.
Motor nerves pass signals from the brain or the spinal cord to the effector organs.
Synapse is a point of contact between the axon of one neuron with the dendrites of another.
Acetylcholine is a neurotransmitter, and serves as a transmitter of nerve impulses within the central and the peripheral nervous systems.
