Which of the following structures passes through the jugular foramen?
Which of the following structures passes through the jugular foramen?
It is formed by the temporal bone and the occipital bone. It allows many structures to pass, including the inferior petrosal sinus, three cranial nerves, the sigmoid sinus, and meningeal arteries….

Which foramen each cranial nerve passes through to enter or exit the skull?
Foramen spinosum (S): This foramen is the smallest and most lateral of those found in the middle cranial fossa, and lies posterior and lateral to the foramen ovale. It allows the middle meningeal artery to enter the skull.
Which cranial nerve passes through the foramen?
The maxillary nerve (V2) passes through the foramen rotundum and into the infraorbital canal, where, at the pterygopalatine fossa, it branches into the pterygopalatine ganglion, with parasympathetic and sensory branches to the paranasal sinuses.
Where do cranial nerves exit skull?
jugular foramen
Cranial nerve 11 is an efferent nerve originating from the brainstem and spinal cord. It exits the skull through the jugular foramen, acting to enable phonation and movements of the head and shoulders.
Which of the following cranial nerves does not exit the skull through the jugular foramen?
hypoglossal nerve
The hypoglossal nerve does not traverse the jugular foramen; however, it joins the nerves exiting the jugular foramen just below the skull base and runs with them in the carotid sheath.
Which of the following nerves exits the skull through the foramen ovale?
The mandibular nerve
The mandibular nerve (V3) exits the cranium through the foramen ovale (Figures 2.2 and 2.3). On its extracranial course, it divides into three main branches: the buccal, mental, and auriculotemporal nerves.
What passes through the foramina of the skull?
The foramina of the skull are narrow openings that allow the passage of nerves and blood vessels.
How does the abducens nerve exit the skull?
The abducens nerve originates from neuronal cell bodies located in the ventral pons. These cells give rise to axons that course ventrally and exit the brain at the junction of the pons and the pyramid of the medulla. The nerve of each side then travels anteriorly where it pierces the dura lateral to the dorsum sellae.
Where is 7th cranial nerve located?
brainstem
Where is the 7th Cranial Nerve located? The two 7th Cranial Nerves (CN VII) are located on either side of the brainstem, at the top of the medulla. They are mixed cranial nerves with BOTH sensory and motor function. CN VII controls the face and is mainly FACE MOVEMENT with some face sensation.
What goes through each foramen in skull?
In anatomy, a foramen is any opening. Foramina inside the body of humans and other animals typically allow muscles, nerves, arteries, veins, or other structures to connect one part of the body with another. The human skull has numerous foramina through which cranial nerves, arteries, veins, and other structures pass.
How do you remember where the cranial nerves exit?
Remembering cranial nerve names in order of CN I to CN XII:
- On old Olympus’s towering top a Finn and German viewed some hops.
- Ooh, ooh, ooh to touch and feel very good velvet. Such heaven!
