The jugular fossa is located in the temporal bone, posterior to the carotid canal and the cochlear aqueduct.. In the bony ridge dividing the carotid canal from the jugular fossa is the small inferior tympanic canaliculus for the passage of the tympanic branch of the glossopharyngeal nerve.
A jugular foramen is one of the two (left and right) large foramina (openings) in the base of the skull, located behind the carotid canal. 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.
posterior cranial fossa: jugular foramen: 2: internal jugular vein, inferior petrosal sinus, sigmoid sinus: glossopharyngeal nerve (IX), vagus nerve (X), accessory nerve (XI) temporal: posterior cranial fossa: stylomastoid foramen: 2: stylomastoid artery: facial nerve (VII) occipital: posterior cranial fossa: hypoglossal canal: 2-hypoglossal ...
Extending lateralward from the posterior half of the condyle is a quadrilateral plate of bone, the jugular process, excavated in front by the jugular notch, which, in the articulated skull, forms the posterior part of the jugular foramen. The jugular notch may be divided into two by a bony spicule, the intrajugular process, which projects ...
The external opening of carotid canal (Latin: "apertura externa canalis carotici") is located upon the inferior aspect of the petrous part of the temporal bone.It is situated anterior to the jugular fossa (the two being separated by a ridge upon which the tympanic canaliculus opens inferiorly), [3] and posterolateral to the foramen lacerum.
A glomus jugulare tumor grows in the temporal bone of the skull, in an area called the jugular foramen. The jugular foramen is also where the jugular vein and several important nerves exit the skull. This area contains nerve fibers, called glomus bodies. Normally, these nerves respond to changes in body temperature or blood pressure.
The hypoglossal canal is a foramen in the occipital bone of ... entry near the medulla oblongata to its exit from the base of the skull near the jugular foramen. [2] ...
The tympanic canaliculus (also Jacobson's canaliculus, tympanic canal, inferior tympanic canaliculus, or temporal canaliculus) is a minute canal in the bony ridge that separates the carotid canal and jugular foramen.
