| ramus sinus cavernosi arteriae carotidis arteriae | <anatomy, artery> A number of small branches of the cavernous part of the internal carotid artery. See: ganglionic branch of internal carotid artery, basal tentorial branch of internal carotid artery, marginal tentorial branch of internal carotid artery. Synonym: ramus sinus cavernosi arteriae carotidis arteriae, cavernous arteries. (05 Mar 2000) |

| pars basalis arteriae pulmonalis | See: right pulmonary artery, left pulmonary artery. (05 Mar 2000) |
| pars cavernosa arteriae carotidis internae | <anatomy, artery> The tortuous portion of the internal carotid artery located within the cavernous sinus; it has numerous small branches. Synonym: pars cavernosa arteriae carotidis internae. (05 Mar 2000) |
| pars cervicalis arteriae carotidis internae | <anatomy, artery> The unbranched portion located in the neck. Synonym: pars cervicalis arteriae carotidis internae. (05 Mar 2000) |
| pars intracranialis arteriae vertebralis | See: vertebral artery. (05 Mar 2000) |
| pars petrosa arteriae carotidis internae | <anatomy, artery> The part of the internal carotid artery in the carotid canal; its branches are carotidotympanic arteries and the artery of the pterygoid canal. Synonym: pars petrosa arteriae carotidis internae, petrous bone. (05 Mar 2000) |
| pars precommunicalis arteriae cerebri anterior | pars precommunicalis arteriae cerebri anterior |
| pars transversaria arteriae vertebralis | <anatomy, artery> Paired arteries which supply the muscles of the neck, spinal cord and cerebellum. (27 Sep 1997) |
| venae haemorrhoidales mediae | Outmoded term for middle rectal veins. (05 Mar 2000) |
| venae hepaticae mediae | Veins draining the central portion of the liver (the superior anterior segment [VIII] and the left side of the inferior anterior segment [V] of the right lobe and the medial segment [IV] of the left lobe) which join to form a trunk that merges with that of the left hepatic veins about 90% of the time prior to entering the left side of the inferior vena cava. Synonym: venae hepaticae mediae. (05 Mar 2000) |
| venae meningeae mediae | The venae comitantes of the middle meningeal artery that empty into the pterygoid plexus. Synonym: venae meningeae mediae. (05 Mar 2000) |
| venae rectales mediae | Several veins that pass from the rectal venous plexus (in which they anastomose with the superior rectal veins) to the internal iliac vein, which ultimately drains into the inferior vena cava. Since the superior rectal veins ultimately drain into the portal vein, the middle retal veins participate in a portocaval anastomosis, and the rectal venous plexus is subject to varicosities during portal hypertension. Synonym: venae rectales mediae. (05 Mar 2000) |
| cellulae mediae | The middle group of air cells of the ethmoidal sinus's; each sinus communicates with the middle meatus of the nasal cavity. Synonym: sinus ethmoidales mediae, cellulae mediae, middle cells, middle ethmoidal sinuses. (05 Mar 2000) |
| sinus ethmoidales mediae | The middle group of air cells of the ethmoidal sinus's; each sinus communicates with the middle meatus of the nasal cavity. Synonym: sinus ethmoidales mediae, cellulae mediae, middle cells, middle ethmoidal sinuses. (05 Mar 2000) |
| ala major ossis sphenoidalis | Strong squamous processes extending in a broad superolateral curve from the body of the sphenoid bone. The greater wing presents these suraces (facies): 1) cerebral surface: forms anterior third of the floor of the lateral portions of the middle cranial fossa; 2) temporal surface: forms the deepest portion of the temporal fossa; 3) infratemporal surface, forms the "roof" of the infratemporal fossa; 4) orbital surface: forms posterolateral wall of orbit. The greater wing forms the inferior border of the supraorbital fissure, and is perforated at its root by foramina rotundum ovale, and spinosum and the pterygoid canal. Synonym: ala major ossis sphenoidalis, ala temporalis. (05 Mar 2000) |
