Question

How is the structure of the olfactory tract?

Answer 1

Hint: Olfactory tract is made up of the axons of mitral relay neurons. The olfactory system refers to the biological structures that aid in the perception of scent. The system comprises the nose and nasal cavities, which support the olfactory mucous membrane for smell perception in the upper portions and operate as respiratory passageways in the lower sections.

Complete answer:
The olfactory bulb is a component in animals' forebrain that receives neurological input concerning scents perceived by nasal cavity cells. Olfactory receptor (smell receptor) cells have axons that extend directly into the highly structured olfactory bulb, where scent information is processed.
The olfactory tract is a bilateral bundle of afferent nerve fibres that connects the piriform cortex, amygdala, and entorhinal cortex to many target locations in the brain, including the mitral and tufted cells of the olfactory bulb. It's a slender white band with a triangular coronal part and an upward-directed apex.
It is located in the olfactory sulcus on the frontal lobe's inferior surface and divides into two striae, a medial olfactory stria and a lateral olfactory stria, posteriorly. The antero-lateral part of the olfactory tubercle, the dorsal and external parts of the anterior olfactory nucleus, the frontal and temporal parts of the prepyriform area, the cortico-medical group of amygdaloid nuclei, and the nucleus of the stria terminalis appear to be where olfactory tract fibres end.
The senses of touch, pressure, pain, and temperature are divided into two categories: general sensations and particular sensations, which include vision, hearing, taste, smell, and the sense of bodily position and movement. The olfactory nerve is the first of the 12 cranial nerves, and it is one of the few that simply conveys sensory information. Our sense of smell is controlled by the olfactory nerve in this scenario.

Note:-
In the phylogenetic history of mammals, the olfactory system is one of the oldest sense modalities. The olfactory system senses food and influences social and sexual behaviour as a chemical sensor. The only group of neurons capable of regeneration is the specialised olfactory epithelial cells.
