Meningohypophyseal Artery
The meningohypophyseal artery, or meningohypophyseal trunk, is an inconstant branch of the cavernous segment of the internal carotid artery. Classically, the meningohypophyseal artery has three named branches: #Dorsal meningeal artery #Inferior hypophyseal artery The inferior hypophysial artery is an artery in the head. It is a branch of the cavernous carotid artery, itself from the internal carotid artery. It supplies the posterior pituitary of the pituitary gland. Structure The inferior hypophysial ar ... #Tentorial artery (artery of Bernasconi and Cassinari, also known as the "Italian" artery) References * Arteries of the head and neck {{circulatory-stub ...

Cavernous Part Of Internal Carotid Artery
The internal carotid artery (Latin: arteria carotis interna) is an artery in the neck which supplies the anterior circulation of the brain. In human anatomy, the internal and external carotids arise from the common carotid arteries, where these bifurcate at cervical vertebrae C3 or C4. The internal carotid artery supplies the brain, including the eyes, while the external carotid nourishes other portions of the head, such as the face, scalp, skull, and meninges. Classification Terminologia Anatomica in 1998 subdivided the artery into four parts: "cervical", "petrous", "cavernous", and "cerebral". However, in clinical settings, the classification system of the internal carotid artery usually follows the 1996 recommendations by Bouthillier, describing seven anatomical segments of the internal carotid artery, each with a corresponding alphanumeric identifier—C1 cervical, C2 petrous, C3 lacerum, C4 cavernous, C5 clinoid, C6 ophthalmic, and C7 communicating. The Bouthillier nomencla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inferior Hypophyseal Artery
The inferior hypophysial artery is an artery in the head. It is a branch of the cavernous carotid artery, itself from the internal carotid artery. It supplies the posterior pituitary of the pituitary gland. Structure The inferior hypophysial artery is a branch of the cavernous carotid artery, itself from the internal carotid artery. Alternatively, it may arise from the meningohypophyseal artery. It passes across the middle of the cavernous sinus. It reaches the lateral surface of the posterior pituitary. It merges with the other inferior hypophysial artery. The inferior hypophysial artery may give off the medial clival artery. Function The inferior hypophysial artery supplies the pituitary gland, specifically the posterior pituitary (neurohypophysis). It is important for distributing vasopressin into the bloodstream. History The inferior hypophysial artery was first identified in 1860 by Hubert von Luschka. References [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
