| foramen diaphragmatis sellae | <anatomy> A hole in the centre of the diaphragm of the sella turcica giving passage to the infundibulum of the hypothalamus. (05 Mar 2000) |
| foramen epiploicum | <anatomy> An alternate term for epiploic foramen. (05 Mar 2000) |
| foramen ethmoidale | Either of two foramina formed by grooves on either edge of the ethmoidal notch of the frontal bone, and completed by similar grooves on the ethmoid bone: anterior ethmoidal foramen, located in an anterior position; posterior ethmoidal foramen located in a posterior position. Synonym: foramen ethmoidale. (05 Mar 2000) |
| foramen frontale | An occasional small opening in the supraorbital margin of the frontal bone medial to the supraorbital foramen. Synonym: foramen frontale. (05 Mar 2000) |
| foramen incisivum | One of several (usually four) openings of the incisive canals into the incisive fossa. Synonym: foramen incisivum, incisor foramen, Stensen's foramen. (05 Mar 2000) |
| foramen infraorbitale | The external opening of the infraorbital canal, on the anterior surface of the body of the maxilla. Synonym: foramen infraorbitale. (05 Mar 2000) |
| foramen interventriculare | The short, often slitlike passage that, on both the left and right side, connects the third brain ventricle (of the diencephalon) with the lateral ventricles (of the cerebral hemispheres); the passage is bounded anteriomedially by the column of fornix and posterolaterally by the anterior pole of the thalamus. Synonym: foramen interventriculare, Monro's foramen, porta. (05 Mar 2000) |
| foramen intervertebrale | One of a number of openings into the vertebral canal bounded by the pedicles of adjacent vertebrae above and below, the vertebral body (mostly of the superior vertebra) and intervertebral disc anteriorly, and the articular processes forming the zygopophyseal joint posteriorly. Synonym: foramen intervertebrale. (05 Mar 2000) |
| foramen ischiadicum | Either of two foramina formed by the sacrospinous and sacrotuberous ligaments crossing the sciatic notches of the hip bone: greater sciatic foramen and lesser sciatic foramen. Synonym: foramen ischiadicum. (05 Mar 2000) |
| foramen jugulare | A passage between the petrous portion of the temporal bone and the jugular process of the occipital, sometimes divided into two by the intrajugular processes; it contains the internal jugular vein, inferior petrosal sinus, the glossopharyngeal, vagus, and accessory nerves, and meningeal branches of the ascending pharyngeal and occipital arteries. Synonym: foramen jugulare, foramen lacerum posterius. (05 Mar 2000) |
| foramen lacerum | <anatomy> An irregular aperture, filled with cartilage (basilar cartilage) in the living, located between the apex of the petrous part of the temporal bone, the body of the sphenoid, and the basilar part of the occipital bones. Several structures pass along the margins of the foramen in a nearly horizontal direction but no structures pass through vertically. Synonym: foramen lacerum medium, lacerated foramen, sphenotic foramen. (05 Mar 2000) |
| foramen lacerum anterius | A cleft between the greater and the lesser wings of the sphenoid establishing a channel of communication between the middle cranial fossa and the orbit, through which pass the oculomotor and trochlear nerves, the ophthalmic division of the trigeminal nerve, the abducens nerve, and the ophthalmic veins. Synonym: fissura orbitalis superior, foramen lacerum anterius, sphenoidal fissure. (05 Mar 2000) |
| foramen lacerum medium | <anatomy> An irregular aperture, filled with cartilage (basilar cartilage) in the living, located between the apex of the petrous part of the temporal bone, the body of the sphenoid, and the basilar part of the occipital bones. Several structures pass along the margins of the foramen in a nearly horizontal direction but no structures pass through vertically. Synonym: foramen lacerum medium, lacerated foramen, sphenotic foramen. (05 Mar 2000) |
| foramen lacerum posterius | A passage between the petrous portion of the temporal bone and the jugular process of the occipital, sometimes divided into two by the intrajugular processes; it contains the internal jugular vein, inferior petrosal sinus, the glossopharyngeal, vagus, and accessory nerves, and meningeal branches of the ascending pharyngeal and occipital arteries. Synonym: foramen jugulare, foramen lacerum posterius. (05 Mar 2000) |
