Which structures are contained in the posterior cranial fossa?

• A. Cerebellum, pons, and medulla
• B. Cerebrum and thalamus
• C. Frontal lobe only
• D. Olfactory bulbs

Answer: (A)

The posterior cranial fossa houses the hindbrain and the brainstem. This deep posterior compartment contains the cerebellum tucked along the back of the skull base and the brainstem structures, including the medulla and the pons. In contrast, the cerebrum and thalamus sit above the tentorium in the supratentorial space, not in the posterior fossa. The frontal lobe is part of the anterior cranial fossa, and the olfactory bulbs are also located in the anterior cranial region near the nasal cavity. So the structures that reside in the posterior cranial fossa are the cerebellum, the pons, and the medulla.
