• A. Great vein of galen
• B. Pineal gland
• C. Fornix
• D. Falx cerebri

Answer 1

The Correct Option is C

In the given question, we need to identify the structure marked by a red arrow in the provided image from the options listed. Let's explore each option to understand the correct answer:
1. Great vein of Galen: This is a major cerebral vein located posteriorly in the brain, responsible for draining blood from the brain into the straight sinus.
2. Pineal gland: A small endocrine gland in the brain responsible for the secretion of melatonin, located near the center of the brain.
3. Fornix: This is an arch-like structure beneath the corpus callosum in the brain, serving as a major fiber tract connecting the hippocampus and mammillary bodies.
4. Falx cerebri: A dural fold that descends vertically in the longitudinal fissure between the cerebral hemispheres.
The structure marked by a red arrow is identified as the Fornix. It is part of the limbic system and involved in memory functions, positioned as an arch-shaped structure under the corpus callosum, consistent with its description among the options. Therefore, the correct answer is:

Fornix
