Question

question 2 of 10
the cells in your nose that detect smell are a type of:
a. mechanoreceptor.
b. chemoreceptor.
c. proprioceptor.
d. efferent receptor.

Explanation:

To solve this, we analyze each option:

• Mechanoreceptors detect mechanical stimuli (like pressure, touch), not smell. So A is incorrect.
• Chemoreceptors detect chemical substances. Smell detection involves detecting odorant chemicals, so nasal smell - detecting cells are chemoreceptors.
• Proprioceptors sense body position/movement, not smell. So C is incorrect.
• “Efferent receptor” is not a standard receptor type for smell; efferent refers to motor output, not sensory detection of smell. So D is incorrect.

Answer:

B. chemoreceptor.
