The image shows a basal view of a brain prosection, with the frontal lobe at the top of the image and the cerebellum and brainstem at the bottom of the image. The blue arrow indicates the olfactory tract, the structure connecting the olfactory bulb on each side with the olfactory cortex where impulses are interpreted.

a
Olfactory tract
QuestionChoice
The image shows a basal view of a brain prosection, with the frontal lobe at the top of the image and the cerebellum and brainstem at the bottom of the image. The olfactory nerves are found in the mucosa of the superior wall of the nasal cavity, and their axons pass into the skull through the perforations of the cribriform plate of the ethmoid bone at the base of the skull (anterior cranial fossa). The olfactory nerves synapse with secondary neurons in the olfactory bulbs, one of which is visible in the image (on the right side of the brain and left side of the image, respectively). However, the blue arrow indicates the olfactory tract, the structure connecting the olfactory bulb on each side with the olfactory cortex where impulses are interpreted.

Olfactory nerve
QuestionChoice
The image shows a basal view of a brain prosection, with the frontal lobe at the top of the image and the cerebellum and brainstem at the bottom of the image. The gyrus rectus is the area of the cortex located immediately medial to the structure indicated by the arrow. However, the blue arrow indicates the olfactory tract, the structure connecting the olfactory bulb on each side with the olfactory cortex where impulses are interpreted.

Gyrus rectus
QuestionChoice
The image shows a basal view of a brain prosection, with the frontal lobe at the top of the image and the cerebellum and brainstem at the bottom of the image. The optic nerve is not visible in this image, as it has been dissected away. The optic chiasm and the optic tracts bilaterally are visible, which lie posterior to the optic nerves. However, the blue arrow indicates the olfactory tract, the structure connecting the olfactory bulb on each side with the olfactory cortex where impulses are interpreted.

Optic nerve
QuestionChoice
The image shows a basal view of a brain prosection, with the frontal lobe at the top of the image and the cerebellum and brainstem at the bottom of the image. The olfactory bulb is the structure whereby the olfactory nerves passing through the cribriform plate of the ethmoid bone synapse with the secondary neurons on the olfactory pathway. It is only visible in the image on the right side of the brain and the left side of the image, respectively. However, the blue arrow indicates the olfactory tract, the structure connecting the olfactory bulb on each side with the olfactory cortex where impulses are interpreted.
