上壁是颅中窝的一部分，骨质薄，参与组成蝶鞍，其内承垂体，前部形成视交叉沟，容纳视交叉;下壁为鼻后孔上缘及鼻咽顶部;内侧壁即骨性蝶窦中隔，常偏向一侧;外侧壁为颅中窝的一部分，与海绵窦、颈内动脉、眼动脉及第Ⅱ、Ⅲ、Ⅳ、Ⅴ、Ⅵ对脑神经关系密切;后壁较厚，与颅后窝内的脑桥及基底动脉相邻。 筛窦为蜂窝状气房结构，位于鼻腔外上方筛骨内、鼻腔外侧壁上部与眼眶之间、蝶窦之前、颅前窝之下。 筛窦中开口于中鼻道者为前组筛窦，开口于上鼻道者为后组筛窦。 …

The sella turcica's most inferior portion is known as the hypophyseal fossa (the "seat of the saddle"), and contains the pituitary gland (hypophysis). In front of the hypophyseal fossa is the tuberculum sellae .

2025年1月17日 · The hypophysial fossa is a depression located in the sphenoid bone of the skull. It serves as a housing for the pituitary gland, also known as the "master gland" due to its crucial role in regulating various bodily functions.

The hypophyseal fossa is the hollow indentation found on the top surface of the body of sphenoid bone. It serves as a space for the pituitary gland, also known as the hypophysis cerebri. This area is enclosed by two bony edges: the tuberculum sellae …

2025年1月20日 · The pituitary gland is located in the pituitary fossa (sella turcica) of the sphenoid bone. Superiorly, the pituitary gland is covered by the circular diaphragma sellae of dura mater. Anteroinferiorly, the gland faces the sphenoid sinus, anterosuperiorly the optic chiasm and laterally the cavernous sinus.

2024年5月21日 · The hypophysial fossa or pituitary fossa (seat of the saddle) sits in the middle of the sella turcica. It is a depression in the body of the sphenoid, which holds the pituitary gland. The dorsum sellae (back of the saddle) forms the posterior wall of the sella turcica. It is a large square of bone, pointing upwards and forwards.

2024年6月26日 · The pituitary (hypophyseal) fossa or sella turcica is a midline, dural lined structure in the sphenoid bone, which houses the pituitary gland. The anterior, inferior and posterior walls are bony, while the lateral walls and roof are formed by dural slings between the anterior and posterior clinoid processes (see below).

The Hypophysial Fossa, located in the middle cranial fossa, is an indentation in the sphenoid bone that houses the pituitary gland (hypophysis cerebri) and is roofed by the diaphragma sella. AI generated definition based on: The Eye (Fourth Edition), 2016

Hypophysial Fossa: Deepest part, housing the pituitary gland. Clivus : A shallow depression behind the dorsum sellae, leading to the basilar part of the occipital bone. Lateral aspects relate to the cavernous sinus and the foramen lacerum region.

2025年2月6日 · Gross anatomy. The pituitary gland sits atop the base of the skull in a concavity within the sphenoid bone called the sella turcica (pituitary fossa), immediately below the hypothalamus and optic chiasm.On average, the pituitary gland measures 12 mm in coronal diameter, 8 mm in AP diameter, and 9 mm high 13.. The anterior lobe of the pituitary is surrounded by a thin fibrous capsule, similar ...
