Foramen ovale. The foramen ovale is an opening in the greater wing of the sphenoid bone. [1] The foramen ovale is one of two cranial foramina in the greater wing, the other being the foramen spinosum. [2]: 771 The foramen ovale is posterolateral to the foramen rotundum and anteromedial to the foramen spinosum.
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; Interventricular foramen, channels connecting ventricles in the brain
The first is the foramen ovale (the valve present between them called eustachian valve) which shunts blood from the right atrium to the left atrium. The second is the ductus arteriosus which shunts blood from the pulmonary artery (which, after birth, carries blood from the right side of the heart to the lungs) to the descending aorta.
Lateral to the foramen ovale is the foramen spinosum, for the passage of the middle meningeal vessels, and a recurrent branch from the mandibular nerve. Medial to the foramen ovale is the foramen lacerum ; in the fresh state the lower part of this aperture is filled up by a layer of fibrocartilage , while its upper and inner parts transmit the ...
The foramen ovale becomes the fossa ovalis as the foramen closes while edge of the septum secundum in right atrium becomes the anulus ovalis, so the depression beneath it becomes the fossa ovalis. [2] [unreliable medical source?] This enables respiration and circulation independent from the mother's placenta.
Foramen ovale (heart), in the fetal heart, a shunt from the right atrium to left atrium; Foramen ovale (skull), at the base of the skull, one of the holes that transmit nerves through the skull; Patent foramen ovale, a small channel in the heart, a remnant of the fetal foramen ovale
The accessory meningeal artery (also accessory branch of middle meningeal artery, pterygomeningeal artery, small meningeal or parvidural branch) is a branch of the maxillary artery that ascends through the foramen ovale to enter the cranial cavity and supply the dura mater of the floor of the middle cranial fossa and of the trigeminal cave, and to the trigeminal ganglion (representing the main ...
The large sensory root of mandibular nerve emerges from the lateral part of the trigeminal ganglion and exits the cranial cavity through the foramen ovale. The motor root (Latin: radix motoria s. portio minor ), the small motor root of the trigeminal nerve , passes under the trigeminal ganglion and through the foramen ovale to unite with the ...
