Which Bony Seat Holds Your Pituitary Gland?
The pituitary rests in a depression of the sphenoid bone called the sella turcica. Its stalk connects toward the hypothalamus through an opening in the dural roof, so this bony seat is not a sealed capsule.

What the illustration shows
English anatomical poster on a navy field. An enlarged opened skull-base cutaway shows a solid peach pituitary gland resting in an ivory sphenoid bony seat. A stalk rises through an opening in the blue-white dural roof toward the hypothalamus. Labels identify the hypothalamus, stalk, gland, sella turcica, sphenoid bone and diaphragma sellae. A side-view head inset locates the skull-base region; an enlarged detail shows the stalk aperture and dural roof. Text distinguishes a bony seat from a sealed capsule. Gold AllHumanBody.com and the project slogan finish the poster.
How to interpret this poster
- Generated skull-base texture and gland shape are illustrative, not measurements or a scan. No empty-sella interpretation, hormone diagnosis or surgical guidance.
- AI-assisted educational illustration; not physician certification, microscopy, a diagnosis or individualized medical advice.
- Fine annotations need enlargement; the full description provides an accessible text alternative.
- Display the full uncropped illustration; do not trim titles, legends or boundary annotations.
