Identify the marked structure in the image.
Show Hint
Posterior cranial fossa, below the tentorium - the little brain.
Updated On: Jun 23, 2026
- Cerebrum
- Brain stem
- Corpus callosum
- Cerebellum
Show Solution
The Correct Option is D
Solution and Explanation
Step 1: Use the position of the marked part. It sits in the posterior cranial fossa, below the tentorium and behind the brain stem - a textbook description of the cerebellum.
Step 2: Confirm by function and relations. The cerebellum coordinates movement and balance, lies inferior to the occipital and temporal lobes, and is roofed by the tentorium cerebelli separating it from the cerebrum.
Step 3: The fourth ventricle lies between it and the ventrally placed pons, anchoring it firmly in the posterior fossa.
Step 4: Rule out the rest: the cerebrum is supratentorial, the brain stem is the anterior stalk, and the corpus callosum is a deep midline white-matter band. The marked structure is therefore the cerebellum.
\[\boxed{\text{Cerebellum}}\]
