(二)垂體周圍的重要神經血管結構
1. superiorly
- 下丘腦。The pituitarygland projects from the inferior aspect of thehypothalamus.
- 鞍膈。The pituitarygland is covered by a dural fold (diaphragm sella).
- 內含視交叉的鞍上池(suprasellarcistern containing the optic chiasm.)
2. laterally
- 海綿竇。cavernoussinuses (a large, thin-walled venous plexus).
- 海綿竇內含頸內動脈,動眼、滑車、外展、眼和上頜神經。The cavernoussinuses contain the internal carotid artery and cranial nerves III,(oculomotor), IV (trochlear), V [trigeminal, branches V1 (ophthalmic) and V2(maxillary)], and VI (abducens).
3. anteriorly\inferiorly\posteriorly
- 蝶鞍(Sella turcica)
- 蝶竇(sphenoid sinus)
- 斜坡(clival)
