Pituitary
This image is a low magnification, midsagittal section of a human pituitary stained with hematoxylin and eosin. Note the distinct boundaries between the neurohypophyseal and adenohypophyseal tissues, indicating the different embryological origins of these subdivisions. 5x
Subdivisions >
The terms neurohypophysis and adenohypophysis reflect the embryonic origin of these two subdivisions. Similar terms, posterior and anterior pituitary, are also commonly used for these subdivisions, reflecting their anatomical position.
- Pars distalis
The terms neurohypophysis and adenohypophysis reflect the embryonic origin of these two subdivisions. Similar terms, posterior and anterior pituitary, are also commonly used for these subdivisions, reflecting their anatomical position.
- Pars tuberalis
The terms neurohypophysis and adenohypophysis reflect the embryonic origin of these two subdivisions. Similar terms, posterior and anterior pituitary, are also commonly used for these subdivisions, reflecting their anatomical position.
- Pars intermedia
The terms neurohypophysis and adenohypophysis reflect the embryonic origin of these two subdivisions. Similar terms, posterior and anterior pituitary, are also commonly used for these subdivisions, reflecting their anatomical position.
- Remnants of Rathke's pouch
The terms neurohypophysis and adenohypophysis reflect the embryonic origin of these two subdivisions. Similar terms, posterior and anterior pituitary, are also commonly used for these subdivisions, reflecting their anatomical position.
- Infundibulum
The terms neurohypophysis and adenohypophysis reflect the embryonic origin of these two subdivisions. Similar terms, posterior and anterior pituitary, are also commonly used for these subdivisions, reflecting their anatomical position.
- Pars nervosa
The terms neurohypophysis and adenohypophysis reflect the embryonic origin of these two subdivisions. Similar terms, posterior and anterior pituitary, are also commonly used for these subdivisions, reflecting their anatomical position.
Capsule >
The entire pituitary is surrounded by a dense connective tissue capsule that is continuous with the dura mater. Only a portion of the capsule is retained in this section.
