大脑观察客观世界的哨所是眼球。人们只了解眼球外壁之角膜巩膜,却很少讨论眼球壁里衬托的葡萄膜。葡萄膜属于眼球壁的中间层,按所在部位分前中后三部分。前部葡萄膜位于角膜后晶状体前之空间,分隔成前房和后房供房水驻扎循环,又名虹膜。虹膜好似中间留口的窗帘,组织内生有瞳孔开大的括约肌,遇强光时括约肌收缩使瞳孔变小,在暗光下瞳孔开大肌收缩,将瞳孔散开。 虹膜和脉络膜之间的中部葡萄膜好似腰带,名叫睫状体,前连虹膜后接脉络膜。睫状体前有70～80个突起的房水加工厂称睫状突,把血液加工成同血浆成分相近的透明
The observation posts in the objective world of the brain are the eyeballs. People only know the corneal sclera of the outer wall of the eye, but rarely discuss the wall of the umbilical wall of the uveal. Uveal belongs to the middle layer of the eye wall, according to the site before and after the three parts. Anterior uveal space is located in front of the posterior lens capsule, separated into anterior chamber and posterior chamber for water stationed cycle, also known as the iris. Iris is like the middle of the curtains left in the mouth, tissue endometrial pupil open sphincter, strong light contraction of the sphincter to make the pupil smaller, in the dark light pupil to open the great muscle contraction, the pupil dilated. The central uveal between the iris and the choroid resembles a belt, called the ciliary body, followed by the iris followed by the choroid. Ciliary body in front of 70 to 80 processes of aqueous humor plant said ciliary process, the blood processed into plasma with the composition similar to the transparent
