The pituitary stalk, also known as the infundibular stalk, infundibulum, or Fenderson's funnel, is the connection between the hypothalamus and the posterior pituitary, the posterior lobe of the pituitary gland.
Sinus (anatomy): The ethmoidal infundibulum is the most important of three infundibula of the nose: the frontal infundibulum and the maxillary infundibulum flow into it. Infundibulum of uterine tube: the funnel-like end of the mammal oviduct nearest to the ovary.
The tuber cinereum is a convex mass of grey matter, [3]: 495 a ventral/inferior distention of the hypothalamus forming the floor of the third ventricle. [citation needed] The portion of the tuber cinerum at the base of the infundibulum (pituitary stalk) is the median eminence; [2] the infundibulum extends ventrally/inferiorly from the median eminence to become continuous with the infundibulum.
Also known as the infundibulum or pituitary stalk, the infundibular stalk bridges the hypothalamic and hypophyseal systems. The median eminence is only occasionally included as part of the posterior pituitary. Other sources specifically exclude it from the pituitary. [5]
Infundibulum: A downward extension from the neuroectoderm of the diencephalon in the brain, which forms the posterior pituitary (neurohypophysis). 2. Developmental Stages Formation of Rathke's pouch (4th week of gestation): During the 4th week, an invagination of the oral ectoderm occurs, creating Rathke's pouch.
The median eminence is generally defined as the portion of the ventral hypothalamus from which the portal vessels arise. [1] The median eminence is a small swelling on the tuber cinereum, posterior to and on top of the pituitary stalk; it lies in the area roughly bounded on its posterolateral region by the cerebral peduncles, and on its anterolateral region by the optic chiasm.
The interpeduncular fossa is a somewhat rhomboid-shaped area of the base of the brain. [5 ... infundibulum, and pituitary gland. ... 816 of the 20th edition of Gray's ...
The diaphragma sellae forms a central opening to accommodate the passage of the pituitary stalk (infundibulum) [1] which interconnects the pituitary gland and the hypothalamus. The diaphragma sellae is an important neurosurgical landmark. [1]
