Question

What is the structure of the olfactory tract?

Answer 1

Olfactory tract:

1. The sensory system used for scent is called the olfactory system.
2. Axons from mitral relay neurons compose the olfactory tract.
3. The olfactory tract is a bilateral bundle of afferent nerve fibers that travels to the mitral and tufted cells of the olfactory bulb from the piriform cortex, amygdala, and entorhinal cortex.
4. It is a thin white band with an upward-pointing apex and a triangular coronal portion.
5. The medial orbital gyrus on the inferior surface of each frontal lobe forms the olfactory sulcus, where the olfactory tract and olfactory bulb are located.
