cerebellum
pons
medulla oblongata
Foramina of the Anterior Cranial Fossa
- foramen cecum
- openings in ethmoid’s cribriform plate
Foramina of the Middle Cranial Fossa
- optic canal
- superior orbital fissure
- foramen rotundum
- foramen ovale
- foramen spinosum
- foramen lacerum
Foramina of the Posterior Cranial Fossa
- internal acoustic meatus
- jugular foramen
- foramen magnum

Structures in superior orbital fissure
- oculomotor nerve (CNIII) * 2. trochlear nerve (CNIV) *
- ophthalmic nerve (CNV1) * 4. abducens nerve (CNVI)
- ophthalmic vein
- sympathetic fibers
Structures in foramen rotundum
maxillary nerve (CNV2)
Structures in foramen ovale
- mandibular nerve (CNV3) 2. accessory meningeal artery
Structures in foramen spinosum
- middle meningeal artery
- middle meningeal vein

Structures in foramen lacerum
nothing of consequence; internal carotid artery crosses it horizontally; inlifethis foramen is filled with cartilage, and this cartilage forms the floor of the anterior end of the carotid canal
Structures in internal acoustic meatus
- facial nerve (CNVII)
- vestibulocochlear nerve
(CNVIII) - labyrinthine artery
Structures in jugular foramen
- glossopharyngeal nerve (CNIX)
- vagus nerve (CNX)
- accessory nerve (CNXI)
- sigmoid sinus
- inferior petrosal sinus
Structures in foramen magnum
- brainstem
- vertebral arteries
- spinal nerves
- spinal roots of accessory
nerve (CNXI) 5. meninges - CSF
Structures in hypoglossal canal
hypoglossal nerve (CNXII)
