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.
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 occipital condyles are undersurface protuberances of the occipital bone in vertebrates, which function in articulation with the superior facets of the atlas vertebra.. The condyles are oval or reniform (kidney-shaped) in shape, and their anterior extremities, directed forward and medialward, are closer together than their posterior, and encroach on the basilar portion of the bone; the ...

Apical foramen, the opening at the tip of the root of a tooth; Foramen ovale (heart), an opening 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
The juxtaglomerular apparatus is part of the kidney nephron, next to the glomerulus. It is found between afferent arteriole and the thick ascending limb of the loop of Henle (distal straight tubule) of the same nephron. This location is critical to its function in regulating renal blood flow and glomerular filtration rate. [2] [3]

The carotid sheath is a condensation of the deep cervical fascia [1]: 578 enveloping multiple vital neurovascular structures of the neck, [2] including the common and internal carotid arteries, the internal jugular vein, the vagus nerve (CN X), and ansa cervicalis. [1]: 578 [2] The carotid sheath helps protects the structures contained therein. [2]
