Question

Select the statements that are correct for reflex pathway.
$\left(1\right)$ Afferent neuron receives signal from a sensory organ.
$\left(2\right)$ Efferent neuron receives signal from a sensory organ.
$\left(3\right)$ Efferent neuron carries signals from CNS to the effector.
$\left(4\right)$ Efferent neuron transmits the impulse via a dorsal nerve root into the CNS.

• A. $1,2,3$
• B. $1$ & $3$
• C. Only $1$
• D. $2$ & $4$

Answer 1

Answer: (B)

The reflex pathway comprises at least one afferent neuron and one efferent neuron appropriately arranged in a series. The afferent neuron receives signal from a sensory organ and transmits the impulse via a dorsal nerve root into the CNS. The efferent neuron then carries signals from CNS to the effector.
