| intervertebral foramen | 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) |
| obturator foramen | A large, oval or irregularly triangular aperture in the hip bone, the margins of which are formed by the pubis and the ischium; it is closed in the natural state by the obturator membrane, except for a small opening for the passage of the obturator vessels and nerve. Synonym: foramen obturatum. (05 Mar 2000) |
| olfactory foramen | One of the openings in the cribriform plate of the ethmoid bone, transmitting the olfactory nerves. (05 Mar 2000) |

| ethmoidal foramen | 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) |
| jugular foramen | 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) |
