Question

Sense of smell is perceived by ………………….
A. Occipital lobe
B. Temporal lobe
C. Olfactory lobe
D. Parietal lobe

Answer 1

Hint: The sensory information is processed through the sensory nervous system which is a part of the nervous system. The most common sensory systems are vision, smell, touch, hearing, taste, and balance. The process by which we create a perception of smell is called the sense of smell.

Complete answer:
Senses are the transducers that help us to analyze and interpret the information we receive from the world around us and then, to create our perception of it. The sensory system is composed of sensory neurons, their pathways, and the brain. In humans and some other vertebrates, the smells are identified through olfactory sensory neurons of the olfactory epithelium. When any odor reaches near the nose, it binds with the specific olfactory receptors which are located in the nasal cavity, and transmits its signal through the olfactory system. A pair of club-shaped structures known as olfactory lobes are present on the frontal side of the cerebrum. They have a structure called the olfactory bulb present in them. After the signals are received by the receptors of the nasal cavity, they are collected by glomeruli and are transmitted further to the olfactory bulb. In the olfactory bulb, these signals interact with the parts of the brain and the smell is identified through memory or emotion.

Hence, the correct answer is option (C).

Note: As the olfactory lobes are utilized in the process of smelling, the sense of smelling is also called olfaction. Olfaction serves many functions, such as detecting hazards, pheromones, and also plays an important role in taste.
