Questions and Answers
- 1.
What is the purpose of the Olfactory System?
- A.
Recognise the things we eat
- B.
Sense of smell perceived by the brain
- C.
Recognise the things we see
- D.
Work out what we are hearing
Correct Answer
B. Sense of smell perceived by the brainExplanation
The purpose of the Olfactory System is to perceive the sense of smell and transmit this information to the brain. The olfactory system consists of specialized cells in the nose that detect odor molecules in the air. These cells send signals to the brain, where the sense of smell is processed and interpreted. This allows us to recognize different smells and distinguish between them.Rate this question:

Olfactory Tract
Correct Answer(s)
A. The Nose
D. Cilia
E. Olfactory cells
G. Olfactory bulb
I. Olfactory TractExplanation
The components of the Olfactory System are the Nose, Cilia, Olfactory cells, Olfactory bulb, and Olfactory Tract. The Nose is responsible for detecting and capturing odor molecules. The Cilia are tiny hair-like structures in the nasal cavity that help move the odor molecules towards the Olfactory cells. The Olfactory cells are specialized nerve cells that detect and transmit information about odors to the brain. The Olfactory bulb is where the Olfactory cells send their signals, and it processes and relays the information to other parts of the brain. Finally, the Olfactory Tract carries the processed odor information from the Olfactory bulb to the brain for further processing and interpretation.Rate this question:

The Nose is the main organ of Olfaction.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The nose is indeed the main organ of olfaction. It contains specialized cells called olfactory receptors that are responsible for detecting and interpreting different smells. When we inhale, odor molecules enter the nose and bind to these receptors, triggering a signal that is sent to the brain for processing. Without the nose, our sense of smell would be greatly diminished or nonexistent. Therefore, the statement that the nose is the main organ of olfaction is true.Rate this question:

Cillia are..
- A.
Part of the Olfactory bulb
- B.
Part of the brain
- C.
Tiny hairs inside the nose
Correct Answer
C. Tiny hairs inside the noseExplanation
Cilia are tiny hairs inside the nose. They play a crucial role in the respiratory system by trapping and filtering out dust, debris, and other particles from the air we breathe. The cilia help to prevent these particles from entering the lungs and causing respiratory issues. Additionally, cilia also aid in the sense of smell by capturing odor molecules and sending signals to the brain for interpretation.Rate this question:

Olfactory cells are sensory nerve cells especially adapted for...............
Correct Answer
smellExplanation
Olfactory cells are specialized nerve cells that are specifically adapted for the sense of smell. These cells are located in the nasal cavity and contain receptors that are able to detect different odors in the environment. When these receptors are stimulated by odor molecules, they send signals to the brain, allowing us to perceive and identify various smells. Therefore, the correct answer is "smell".Rate this question:

The long tail like structure of a nerve cell is called an...............................
Correct Answer
axonExplanation
The long tail-like structure of a nerve cell is called an axon. The axon is responsible for transmitting electrical signals away from the cell body to other neurons, muscles, or glands. It is covered by a myelin sheath, which helps to insulate and speed up the conduction of the electrical impulses. The axon plays a crucial role in the communication and coordination of signals within the nervous system, allowing for the transmission of information over long distances.Rate this question:

The Olfactory bulb is situated in the...........................
- A.
Nose
- B.
Mouth
- C.
Brain
Correct Answer
C. BrainExplanation
The correct answer is Brain. The olfactory bulb is a structure located in the brain, specifically in the forebrain. It is responsible for processing and relaying information related to smell. The olfactory bulb receives signals from the olfactory receptors in the nose and sends them to other areas of the brain for further processing and interpretation. This allows us to perceive and distinguish different smells.Rate this question:

The Olfactory Tract.....................................
- A.
Is situated at the entrance to the nose
- B.
Carries perception of smell to the limbic area of the brain
- C.
Recognises taste
- D.
Carries perception of smell to the nostrils
Correct Answer
B. Carries perception of smell to the limbic area of the brainExplanation
The olfactory tract carries the perception of smell to the limbic area of the brain. The limbic area is responsible for emotions, memory, and behavior, and it plays a crucial role in processing and interpreting olfactory information. This is why certain smells can evoke strong emotional responses or trigger memories. The olfactory tract does not recognize taste or carry perception of smell to the nostrils, as these functions are performed by other parts of the olfactory system.Rate this question:

The Limbic area of the Brain links smell to........................................?
Correct Answer
emotionExplanation
The Limbic area of the Brain is responsible for processing emotions and is closely connected to the olfactory system, which is responsible for processing smells. This connection allows the brain to link smells to emotions, meaning that certain smells can trigger specific emotional responses. Therefore, the correct answer is emotion.Rate this question:
