![Also, a term for the F. of Munro. P. ovale cor'dis. (L. ovalis; cor, the heart.) The F. ovale of heart. r. ova'le cox'ae. (L. ovalis; coxa, the hip.) The F. ovale of hip-bone. r. ovale of beart. (L. ovalis. F. trou de Botal; G. eifdrmiges Loch.) An oval aperture in the lower and middle part of the septum between the two auricles of the foetal heart, the result of the incomplete growth backwards of the septum. In the course of the tenth or eleventh week of foetal life a fold of tissue grows from the poste- rior wall of the common auricular cavity, pro- jects towards the advancing auricular septum, passes in front and to the left of the foramen ovale, and by the fifth or sixth month forms a complete valve, which closes the passage of blood from left to right, but not from right to left. At birth this passage of blood from one auricle to the other ceases by the equalisation of pressure, in consequence of the filling of the left auricle with blood from the lungs; and in a few weeks after- wards the fold and the margin of the foramen ovale become united and the aperture becomes closed. Occasionally a small remnant of the opening is left unclosed, which in some cases is so large as to cause the condition called Cyanosis. F. ovale of hip-bone. {L. ovalis.) The F., obturator. r. ovale of spbe'noid. (L. ovalis. Sphe- noid bone. Gr. eirundes Loch.) An oval opening near the posterior margin of the great wing of the sphenoid bone. It lies a little outside and behind the foramen rotundum, and transmits the inferior maxillary nerve and a plexus of veins. r. ovale os'sis pel'vis. (L. ovalis; OS, a bone ; pelvis.) The F., obturator. F. ovale os'sis spbenoi'dei. (L. ovalis; os; sphenoid bone.) See F. ovale of sphenoid. F. ovale, pa'tency of. (L. ovalis; pateo., to lie open.) A congenital condition in which the natural fcetal condition of an unclosed foramen ovale persists after birth. It is a frequent cause of cyanosis, but its presence during life is not, as a rule, indicated by a cardiac murmur. F. palati'num ante'rius. {L.palatum, the palate; anterior, in front.) The incisive foramen. F. palati'num poste'rlus mag'num. (L. palatum ; postey'ior, behind; magnus, great.) The opening of the posterior palatine canal. F. pala'to-maxillary. (L. palatum ; maxilla,i\ie]dLVf.) The F. palatinum posterius magnum. F. Paniz'zse. See i^. of Panizza. F., pari'etal. (L. paries, a wall. F. trou parietal; Gr. Scheitelbeinloch.) An open- ing for the transmission of a vein near the upper border of the parietal bone behind its middle, which establishes a communication between the longitudinal sinus and the veins outside the cranial cavity ; the Fmissarium parietale. F., post-g-le'noid, cat. A foramen de- scribed by Mivart as occasionally present in the cat, which is situated just behind the post- glenoid process, transmits one of the two branches into which the median venous channel, which runs along the median junction of the parietals, divides. F. pro si'nu petro'so inferio'ri. (L. pro, for; sinus, a gulf; petrosus, stony; inferus, that is below.) An aperture, present in about 25 per cent, of cases, situated in front of the foramen jugulare, which permits the passage of the inferior petrosal sinus. F., pter'yg-o-pal'atine. The opening of the pterygo-palatine canal. F. quadra'tum. (L. quadratus, square. F. ouverture de la veine cave inferieure; G. Kohlvenenloch.) The somewhat quadrangular opening in the tendinous centre of the diaphragm, at the hinder part of the junction of its right and middle lobes; it transmits the inferior vena cava. The posterior border is lower than the anterior, and is frequently muscular. F. quadrilat'erum. (L. quatuor, four; latus, a side.) The F. quadratum. F. Rivi'nl. The same as Mivini, notch of. F. Rivinia'num. Same as Rivini, notch of. F. rotun'dum. (L. rotundus, round. F. trou grand rond; Gr. rundes Ljoch.) A round canal perforating the base of the great wing of the sjohenoid bone below the sphenoidal fissure; it opens beneath the orbit and transmits the superior maxillary nerve. It is absent in many animals. F., sa'cro sciatic, great. {Sacrum; sciatic. F. grande echancrure sciatique; G. grosses Sitzbeinloch.) The space between the small sacro-sciatic ligament and the os iunomi- natum ; it transmits the pyriformis muscle, and the gluteal, sciatic, and pudic vessels and nerves. F., sa'cro-sciat ic, small. {Sacrum; sciatic. F. petite echancrure sciatique; G. Meines Sitzbeinloch.) The space bounded by the great and small sacro-sciatic ligaments and the border of the bone lying between the spine and the tuberosity of the ischium; it transmits the obturator internus muscle and the internal pudic vessels and nerve. F. saphe'nse. The Saphenous opening. F. scapula're. (L. scapula, the shoul- der-blade.) A foramen, occasionally present, formed by the ossification of the coracoid liga- ment of the scapula, which bridges over the scapular notch. F. sclerotlcae anti'cum. (L. anticus, in front.) The rim of sclerotic to which the cornea is attached. F. sclerotlcae posti'cum. (L. posticus, behind.) The F. opticum scleroticce. F. sphenoidale ante'rius. {Sphenoid; anterior, that is before.) A foramen, occasion- ally present, at the root of the external ptery- goid process, which, as in the rabbit, permits the passage of the internal maxillary artery. F., sphe'no-pal'atine. {Sphenoid bone; palate hone. F. trou spheno-palatin ; G. li^eil- beingaurnenloch.) The aperture or canal formed by the closure of the spheno-palatine notch of the palate bone by the body of the sphenoid bone, and leading from the spheno-maxillary fossa to the nasal cavity; it transmits the nasal or spheno-palatine bi'anch of the internal maxillary artery, its accompanying vein, and the spheno- palatine nerves from Meckel's ganglion, which lie just on the outer side of the foramen, being the posterior superior nasal and the naso-palatine nerves. F. sphe'no-spino'sum. {Sphenoidhone.) The F. spinosum. F., spi'nal. {G(. Fiickenmarksloch.) Same as F., vertebral. F. spina'le. (L. spina, a thorn.) A synonym of F. spinosum. Also, the same as F., spinal.](https://iiif.wellcomecollection.org/image/b21292917_0003_0008.jp2/full/800%2C/0/default.jpg)
