What does the anterior cranial fossa hold?

Temporal lobe Cerebellum Frontal lobe, olfactory bulb, and attachment for falx cerebri Pituitary gland

Correct Answer:

Frontal lobe, olfactory bulb, and attachment for falx cerebri

Explanation:

The anterior cranial fossa houses the frontal lobes of the brain, the olfactory bulbs and tracts, and the attachment for the falx cerebri. The frontal lobes rest in this forward part of the cranial base, the olfactory apparatus sits on the cribriform plate of the ethmoid within this fossa, and the falx cerebri attaches along the crista galli and frontal crest in this region. Other parts like the temporal lobe are housed in the middle cranial fossa, the cerebellum in the posterior cranial fossa, and the pituitary gland sits in the sella turcica of the sphenoid within the middle cranial fossa. So the combination of frontal lobe, olfactory structures, and falx cerebri attachment best matches the anterior fossa.
