Objective 4 - Sensory Receptors*
Questions and Answers
- 1.
You smell something delicious baking. What kind of sensory receptors receive that information?
- A.
Mechanoreceptors
- B.
Olfactory receptors
- C.
Olfactory receptors
Correct Answer(s)
B. Olfactory receptors
C. Olfactory receptorsExplanation
Olfactory receptors are the sensory receptors responsible for detecting and processing smells. They are located in the nasal cavity and are activated when odor molecules bind to them. These receptors send signals to the brain, allowing us to perceive and identify different smells.Rate this question:

Where are most of our sensory receptors located?
- A.
Muscles
- B.
Skin
- C.
Bones
Correct Answer
B. SkinExplanation
Most of our sensory receptors are located in the skin. The skin contains various types of sensory receptors, such as thermoreceptors for detecting temperature, mechanoreceptors for sensing touch and pressure, and nociceptors for detecting pain. These receptors send signals to the brain, allowing us to perceive and respond to different sensory stimuli from our environment.Rate this question:

______________ receive pressure and touch information.
- A.
Chemoreceptors
- B.
Olfactory receptors
- C.
Mechanoreceptors
Correct Answer
C. MechanoreceptorsExplanation
Mechanoreceptors are sensory receptors that respond to mechanical stimuli such as pressure and touch. They are responsible for detecting and transmitting information about physical sensations to the brain. Chemoreceptors, on the other hand, respond to chemical stimuli, while olfactory receptors specifically detect odors. Therefore, mechanoreceptors are the most appropriate answer as they are directly related to receiving pressure and touch information.Rate this question:

Your little brother passes gas and it smells AWFUL. Which is the best explanation of how the message gets to the brain?
- A.
Olfactory receptors receive scent chemicals, which cause olfactory nerves to send a message to the brain
- B.
Mechanoreceptors in the nose receive pressure information and send it through the olfactory nerve to the brain
- C.
The olfactory nerve captures sent chemicals and sends them to the olfactory receptors
Correct Answer
A. Olfactory receptors receive scent chemicals, which cause olfactory nerves to send a message to the brainExplanation
When your little brother passes gas, odor molecules are released into the air. These molecules are then detected by olfactory receptors in the nose, which are specialized cells that can recognize different scents. Once the receptors detect the scent chemicals, they send a message to the olfactory nerves. These nerves then transmit the message to the brain, where it is processed and interpreted as the unpleasant smell of the gas.Rate this question:

Which type of sensory receptors are found here that can sense taste?
- A.
Chemoreceptors
- B.
Thermoreceptors
- C.
Mechanoreceptors
Correct Answer
A. ChemoreceptorsExplanation
Chemoreceptors are sensory receptors that are responsible for detecting chemical stimuli in the environment. They are specifically designed to sense taste and are found in taste buds located on the tongue and other parts of the mouth. Chemoreceptors are able to detect different molecules and send signals to the brain, allowing us to perceive different tastes such as sweet, sour, salty, and bitter.Rate this question:
