Multiple Choice

Which of the following correctly describes olfactory receptors?

Olfactory receptors are mechanoreceptors that respond to pressure changes in the nasal cavity.

Olfactory receptors are thermoreceptors that sense temperature changes in the nasal cavity.

Olfactory receptors are photoreceptors that detect light in the nasal cavity.

Olfactory receptors are specialized neurons located in the nasal cavity that detect odor molecules.

Verified step by step guidance

Understand the function of olfactory receptors: Olfactory receptors are responsible for detecting odor molecules in the environment.

Identify the type of receptor: Olfactory receptors are a type of chemoreceptor, which means they respond to chemical stimuli, specifically odor molecules.

Locate the olfactory receptors: These receptors are located in the olfactory epithelium, a specialized tissue in the nasal cavity.

Differentiate from other receptor types: Mechanoreceptors respond to mechanical pressure or distortion, thermoreceptors respond to temperature changes, and photoreceptors respond to light. Olfactory receptors do not fit these categories.

Conclude with the correct description: Olfactory receptors are specialized neurons in the nasal cavity that detect odor molecules, making them chemoreceptors, not mechanoreceptors, thermoreceptors, or photoreceptors.
