Question

Center for sense of smell is:
A. Cerebellum
B. Olfactory lobes
C. Cerebrum
D. Midbrain

Answer 1

Hint:
It is one of the special senses, that have directly associated with specific organs. Focus on the word ‘Center’ for the smell.

Complete answer:
The olfactory system is the sensory system used to detect the smell, also known as olfaction. The senses of olfaction are carried by the olfactory nerves to the olfactory lobe which is a part of the cerebrum.
The human sense of smell (olfactory sense) is quite limited. The receptor for the sense of smell is found in the olfactory epithelium of the nasal chambers. From the olfactory bulb, bundles of olfactory nerve fibres run through the olfactory tract (the olfactory bulb and olfactory tract are the parts of the olfactory lobe of the brain). In each cerebral hemisphere (in the temporal lobe), the olfactory nerve fibres connect the olfactory area. It is the region where the impulses are interpreted.
The olfactory lobe is a structure found in the vertebrate forebrain. The olfactory cortex is a component of the cerebral cortex which is a part of the cerebrum.
The cerebellum is mainly involved in muscle control, balance, and in movement.
The midbrain functions in motor movement particularly movements of the eye, and in auditory and visual processing.
The cerebrum is the CENTER for the sense of smell which coordinates with the olfactory lobes.

Option ‘C’ is correct

Note:
These olfactory receptors which are found in the olfactory epithelium, are similar to those for taste in that they are thought to be stimulated by chemicals dissolved in water.
