Here you can see the underside of the brain with the larger cerebral arteries and cranial nerves in an overview without lists. The forehead is located upwards in the picture. Next step: Underside without blood vessels. Rehearsal image.

Step 1.

The underside of the brain without blood vessels with cranial nerves Here you can refresh the memory of the cranial nerves and the various vascular inlets (perforations) that more or less surround the central part of the underside of the brain.

Step 2.

Arteries on the undamaged underside of the brain. Activate and roll out the list: Arteries of the brain 1. Identify the different arteries and check their supply areas. Note the admittedly narrow central/perforating arteries responsible for supplying blood to the central parts of the brain (hypothalamus, thalamus, basal ganglia, capsula internal).

Step 3.

Arteries on the underside of the brain after removal of the cerebellum, brainstem, and anterior part of the left temporal lobe. Activate and unroll the list: Arteries of the brain 2. This step primarily aims to show how the middle cerebral artery exits the insula by using the passage path that the limen insulae offers in the gap between the underside of the frontal lobe and the top of the temporal lobe. The cut surface through the insula border and the base of the insula are marked with grids.
