The ophthalmic artery (OA) is an artery of the head. It is the first branch of the internal carotid artery distal to the carotid sinus. Branches of the ophthalmic artery supply all the structures in the orbit around the eye, as well as some structures in the nose, face, and meninges. Occlusion of the ophthalmic artery or its branches can ...
The superior hypophyseal artery is an artery supplying the pars tuberalis, the infundibulum of the pituitary gland, and the median eminence. It is a branch of the ophthalmic part of the internal carotid artery .
Each posterior communicating artery is situated within the interpeduncular cistern, superolateral to the pituitary gland. [2]: 450 Each are is situated upon the medial surface of the ipsilateral cerebral peduncle [1]: 477 and adjacent to the anterior perforated substance.
The ophthalmic artery and its branches. The anterior cerebral circulation is the blood supply to the anterior portion of the brain including eyes.It is supplied by the following arteries:
The medial palpebral arteries (internal palpebral arteries) are arteries of the head that contribute arterial blood supply to the eyelids. They are derived from the ophthalmic artery; a single medial palpebral artery issues from the ophthalmic artery before splitting into a superior and an inferior medial palpebral artery, [1] each supplying one eyelid.
Defects in infundibulum development can result in a heart condition known as tetralogy of Fallot. A tendinous band extends upward from the right atrioventricular fibrous ring and connects the posterior surface of the infundibulum to the aorta. The infundibulum is the entrance from the right ventricle into the pulmonary artery and pulmonary trunk.
The short posterior ciliary arteries contribute arterial supply to the choroid, ciliary processes, [3] optic disc, the outer retina, and Bruch's membrane. [1]Some branches of the short posterior ciliary arteries supply the optic disc by means of an anastomotic ring - the circle of Zinn-Haller or circle of Zinn - which is associated with the fibrous extension of the ocular tendons (common ...
