The branching pattern of the Aa. carotes internae and the macroscopic blood supply to the hypophysis and hypothalamus of the ostrich were studied on ten dissected acrylic vascular-injected heads and ten corrosion preparations of acrylic vascular casts of the head. The A. carotis cerebralis was found to be the only source of blood supply to the hypophysis and hypothalamus. The neurohypophysis was supplied by the caudal hypophyseal and infundibular arteries. The pars distalis was supplied by portal vessels from the ventral hypothalamic region, and it also received arterial blood directly from the infundibular arteries. The hypothalamus received blood from the Aa. infundibulares. A. ventralis tecti mesencephali and A. preopticae.
在十个解剖的丙烯酸血管注射头部标本和十个头部丙烯酸血管铸型腐蚀标本上，研究了鸵鸟颈内动脉的分支模式以及垂体和下丘脑的宏观血液供应情况。发现大脑颈动脉是垂体和下丘脑唯一的血液供应来源。神经垂体由垂体后动脉和漏斗动脉供血。远侧部由来自下丘脑腹侧区域的门静脉供血，并且它也直接从漏斗动脉接受动脉血。下丘脑接受来自漏斗动脉、中脑顶盖腹侧动脉和视前动脉的血液。
