Visible Human Transverse Section Through the HeadYou selected: sphenoid boneThe spenoid bone forms much of the interior structure of the cranium. It houses the sphenoid air sinuses, as well as the pituitary gland and hypothalamus. These important endocrine organs reside in a bony encasement called the sella tursica or turkish saddle, so named for its 3D resemblance to a saddle. Both secrete factors that regulate endocrine organs such as the thyroid and adrenal glands.eye | lens | medial rectus | lateral rectus | ethmoid sinus | sphenoid sinus | nasal septum | temporalis muscle | brain | Information Module Name: a_vm1110 Module Title: Visible Human Transverse Section Through the Head Image Info: Gross specimen, transverse section Created by: Lynn Bry Contact Email:bryl@medicine.wustl.edu Last modified: Feb 4th, 1997 Created with Annotation 1.0 |
