The bony canal that extends rostrally from the caudal foramen lacerum is called the carotid canal; it transmits the internal carotid artery and postganglionic sympathetic plexus from the superior cervical ganglion (also called the carotid plexus, made up of the carotid nerves; Figure 1-11).

What cranial nerve passes through the carotid foramen?

Cranial nerve IX also briefly enters the carotid sheath at its superior portion, right as it exits the jugular foramen. [8] This nerve’s primary target tissue is the parotid gland, where it supplies parasympathetic innervation.

What travels in carotid canal?

The carotid canal allows the internal carotid artery to pass into the cranium, as well as the carotid plexus traveling on the artery. The carotid plexus contains sympathetics to the head from the superior cervical ganglion.

What travels through the jugular foramen?

Intradurally, the glossopharyngeal, vagus, and accessory nerves leave the intracranial compartment through the jugular foramen. These nerves leave the medulla and upper cervical spinal cord and transverse the lateral cerebellomedullary cistern before entering the jugular foramen (Figure 6).

What vessels pass through the carotid canal and the jugular foramen?

The carotid ridge separates the carotid canal and jugular foramen. Meningeal branches of the ascending pharyngeal and occipital arteries enter the jugular foramen. The glossopharyngeal, vagus, and accessory nerves pass through the jugular foramen on the medial side of the jugular bulb.

Where is the carotid foramen?

The carotid canal is a passage within the petrous temporal bone and transmits the internal carotid artery and sympathetic plexus. Its inferior opening is called the carotid foramen and is situated anteriorly to the jugular fossa and medially to the carotid plate.

Where does internal carotid enter skull?

The internal carotid artery runs upward through the neck and enters the skull through the carotid canal, located in the petrous portion of the temporal bone just superior to the jugular fossa. Within the anterior portion of the canal, only thin bone separates the artery from the cochlea and the trigeminal ganglion.

Does the internal jugular vein pass through the jugular foramen?

Contents. The jugular foramen may be subdivided into three compartments, each with their own contents. The posterior compartment transmits the sigmoid sinus (becoming the internal jugular vein), and some meningeal branches from the occipital artery and ascending pharyngeal artery.

Is the carotid canal and the carotid foramen the same thing?

The carotid canal is a passage within the petrous temporal bone and transmits the internal carotid artery and sympathetic plexus. Its inferior opening is called the carotid foramen and is situated anteriorly to the jugular fossa and medially to the carotid plate.

What passes through the jugular foramen quizlet?

the jugular foramen with glossopharyngeal nerve, vagus nerve, and one vein, the internal jugular vein.

Where does the jugular vein pass through?

jugular vein, any of several veins of the neck that drain blood from the brain, face, and neck, returning it to the heart via the superior vena cava.

Which of the following does not pass through the jugular foramen?

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.

What structure passes through foramen spinosum?

The foramen spinosum permits the passage of the middle meningeal artery, middle meningeal vein, and the meningeal branch of the mandibular nerve.

What passes through hypoglossal canal?

Function. The hypoglossal canal transmits the hypoglossal nerve from its point of entry near the medulla oblongata to its exit from the base of the skull near the jugular foramen.

What passes through stylomastoid foramen?

The stylomastoid foramen is a small round opening between the styloid process and anterior end of the digastric groove that transmits the stylomastoid artery and the extratemporal segment of CN VII after traveling through the pyramidal eminence.

What structure passes through the foramen magnum?

…a large oval opening, the foramen magnum, through which the medulla oblongata passes, linking the spinal cord and brain.
