Study Notes
- The cranial cavity is divided into three depressions: anterior, middle, and posterior cranial fossae.
- The anterior cranial fossa is the most superior and shallow of the three.
- It accommodates the anteroinferior portions of the frontal lobes of the brain.
- The anterior cranial fossa consists of three bones: the frontal bone, ethmoid bone, and sphenoid bone.
- The frontal crest is a bony landmark in the midline of the frontal bone that acts as a site of attachment for the falx cerebri.
- The crista galli is a bony landmark in the midline of the ethmoid bone that acts as another point of attachment for the falx cerebri.
- The cribriform plate is a sheet of bone on either side of the crista galli that contains numerous small foramina transmitting olfactory nerve fibers into the nasal cavity.
- The lesser wings of the sphenoid bone separate the anterior and middle cranial fossae.
- The ethmoid bone contains the main foramina of the anterior cranial fossa.
- Fracture of the cribriform plate can have major consequences.

Description
Test your knowledge of the anterior cranial fossa with this informative quiz. Learn about the bones that make up this important area of the skull and the bony landmarks that act as attachment sites for the falx cerebri. Discover the functions of the cribriform plate and the lesser wings of the sphenoid bone, and understand the potential consequences of a cribriform plate fracture. With this quiz, you'll gain a deeper understanding of the anatomy of the anterior cranial fossa.
