As a venous sinus, the cavernous sinus receives blood from the superior and inferior ophthalmic veins and from superficial cortical veins, and is connected to the basilar plexus of veins posteriorly. The cavernous sinus drains by two larger channels, the superior and inferior petrosal sinuses , ultimately into the internal jugular vein via the ...
This is a list of human anatomy mnemonics, categorized and alphabetized.For mnemonics in other medical specialties, see this list of medical mnemonics.Mnemonics serve as a systematic method for remembrance of functionally or systemically related items within regions of larger fields of study, such as those found in the study of specific areas of human anatomy, such as the bones in the hand ...
accessory meningeal artery, emissary vein connecting cavernous sinus with pterygoid plexus: mandibular nerve (V 3) lesser petrosal nerve (occasionally) [3] sphenoid: middle cranial fossa: foramen spinosum: 2: middle meningeal artery: meningeal branch of the mandibular nerve (V 3) sphenoid: middle cranial fossa: foramen lacerum: 2
This is a list of mnemonics used in medicine and medical science, categorized and alphabetized. A mnemonic is any technique that assists the human memory with information retention or retrieval by making abstract or impersonal information more accessible and meaningful, and therefore easier to remember; many of them are acronyms or initialisms which reduce a lengthy set of terms to a single ...
The intercavernous sinuses are two in number, an anterior and a posterior, and connect the two cavernous sinuses [1] across the middle line.. Intercavernous sinuses. The anterior passes in front of the hypophysis cerebri (pituitary gland), the posterior behind it, and they form with the cavernous sinuses a venous circle (circular sinus) around the hypophysis.
The cavernous section of the internal carotid artery begins at the superior aspect of the petrolingual ligament. For surgeons and radiologists , it is important to be oriented to the location of this ligament in cases of possible dissection of the internal carotid artery, as it helps determine whether the dissection has occurred inside or ...
It runs along the lateral sulcus [1] to empty into either the cavernous sinus, [1] [2] or sphenoparietal sinus. [1] It is adherent to the deep surface of the arachnoid mater bridging the lateral sulcus. It drains the adjacent cortex. [2]
One notable emissary vein, the vein of Vesalius, travels through the sphenoidal emissary foramen inferior to the zygomatic arch, connecting the pterygoid plexus with the cavernous sinus. [3] This is an important route for the spread of infection as cranial nerve VI and the internal carotid pass through the cavernous sinus, with cranial nerves ...
