Question 1 Control and Coordination Set 1

Assertion (A): The olfactory receptors receive the sensation of smell.

Reason (R): The sensory impulse for smell is received by the fore-brain.

  2. These receptors receive the electrical signal and transmits them to the fore-brain.

  3. The fore-brain interprets this signal and detects it as a smell.

  4. Hence, both A and R are true but R is not the correct reason for A.
