The human skull has numerous holes (foramina) through which cranial nerves, arteries, veins and other structures pass.

Bone	Cranial fossa	Foramina	Vessels	Nerves
frontal	-	supraorbital foramen	supraorbital artery, supraorbital vein	supraorbital nerve
frontal	anterior cranial fossa	foramen cecum	emissary veins to superior sagittal sinus from the upper part of the nose
ethmoid	-	foramina of cribriform plate	-	olfactory nerve bundles (I)
ethmoid	anterior cranial fossa	anterior ethmoidal foramen	anterior ethmoidal artery anterior ethmoidal vein	anterior ethmoidal nerve
ethmoid	anterior cranial fossa	posterior ethmoidal foramen	posterior ethmoidal artery posterior ethmoidal vein	posterior ethmoidal nerve
sphenoid	-	optic canal	ophthalmic artery	optic nerve (II)

Spine

Main article: Intervertebral foramina

Within the vertebral column (spine) of vertebrates, including the human spine, each bone has an opening at both its top and bottom to allow nerves, arteries, veins, etc. to pass through.

Other

• Apical foramen, the hole at the tip of the root of a tooth
• Foramen ovale (heart), a hole between the venous and arterial sides of the fetal heart
• Foramen transversarium, one of a pair of openings in each cervical vertebra, in which the vertebral artery travels
• Greater sciatic foramen, a major foramen of the pelvis
• Interventricular foramen, channels connecting ventricles in the brain
• Lesser sciatic foramen, an opening between the pelvis and the posterior thigh
• Obturator foramen, the hole created by the ischium and pubis bones of the pelvis
• Vertebral foramen, the foramen formed by the anterior segment (the body), and the posterior part, the vertebral arch.
