Frontal crest

Frontal Crest is a prominent anatomical feature located in the human skull. It is a ridge of bone found along the midline of the frontal bone, one of the eight bones that make up the cranium. The frontal crest serves as an attachment point for the falx cerebri, a large sickle-shaped fold of dura mater that descends vertically in the longitudinal fissure between the cerebral hemispheres.

Anatomy

The frontal crest starts at the foramen cecum, a small hole located at the front of the skull, and extends backwards along the midline of the frontal bone. It varies in size and shape between individuals, but is generally more pronounced in males than in females.

The falx cerebri, which attaches to the frontal crest, is a dural fold that separates the two cerebral hemispheres. It helps to stabilize the brain within the skull and also contains the superior sagittal sinus, a large venous channel that drains blood from the brain.

Clinical Significance

Due to its location and role as an attachment point for the falx cerebri, damage to the frontal crest can have significant neurological implications. For example, fractures of the frontal bone that involve the frontal crest can lead to cerebrospinal fluid leaks or meningitis. Additionally, abnormalities in the shape or size of the frontal crest may be associated with certain neurological or psychiatric conditions.
