QUESTION 7Olfactory receptor cells are what type of cells?

1. 		Red blood cells
   		White blood cells
   		Neurons
   		Endothelial Cells

Answer 1

Answer

1. Option A) Retina

• Retina is the innermost layer of the eyeball and a part of neural tunic.
• Retina contains photoreceotor cells rods and cones that detect visual stimuli.

2. Option B) Anteroceptors

• Exteroceptors detect stimuli from external environment.
• Interoceptors detect stimuli from internal environment.
• Propiroceptors detect stimuli of mechanical pressure such as to skeletal muscle.
• There are NO receptors as anteroceptors.

3. Option B) Nociceptors

• They are sensory receptors located in various regions in the body such as digestive tract, joints and muscles and sends neural impulses for pain.

4. Option C) Neurons

• Olfactory receptors are sensory neurons that sends impulses of smell to the central nervous system.
