视器及视觉传导路是解剖教学的重点和难点，常规标本困难是示其全貌，学员学习时不易建立其整体观和立体感。为此我们设计了该多功能标本。简介如下：1．设计目标：用一件标本，在显示视器及视觉传导器的同时尽可能多地显露脑的结构。2．制作：选取巨固定的成人头颅，沿外肌、颧弓和外耳门上缘及枕外隆凸的连线去除颅盖，修洁脑膜及血管。1）视器制作：①去除左侧眼眶外侧奎及部分下壁，剖露出眼球下斜肌、下和内直肌及其支配神经、视神经等结构，并向眼球内注入防腐用胶行水平切以显示眼球壁和内容物。②右侧保留完整眼球，并剖露外、上直肌、上斜肌和提上睑肌、眼的血管、神经，并显露眼睑、泪器、结膜等眼附器。2）视觉传导路制作：①在视交叉后Zcm处冠状切除部分额叶。②在左侧大脑半球，沿视神经、视交叉、视束、外侧膝状体、视辐射直至视觉中枢进行顺次解剖以完整显示视觉传导路。去除部分脑组织显示出豆状核及其内侧的内囊白质板。③在右侧大脑半球，距外耳门上方5cm处行水平切，显示内囊及基底核，并在其后外侧剖露出视辐射至视中枢。3）着色、测胶后有机玻璃封装，常规保存。4）体会：①该标本立体、完整地显示了视器及视觉传导路，又显示了内囊、基底核等脑内结构。②左右侧相互弥补，既保持?
Visual and visual conduction path is the focus of anatomical teaching and difficulties, conventional specimens show the full picture of the difficulties, students learn not easy to establish their overall concept and three-dimensional. To this end, we designed the multi-purpose specimen. Brief introduction is as follows: 1. Design Goal: Use a specimen that reveals as much of the brain’s structure as possible while displaying the viewfinder and the visual transmitter. 2. Production: Select a giant fixed adult skull, along the outer muscle, zygomatic arch and the outer edge of the ear and the outer edge of the convex line to remove the cranium, repair the meninges and blood vessels. 1) the production of the visual device: ① remove the lateral orbit outside the left side of the Kui and part of the lower wall, revealing the lower extremity oblique, lower and inner rectus and its dominant nerve, optic nerve and other structures, To show the eye wall and contents. ② The right to retain the complete eye, and cut off, the upper rectus, upper oblique and levator muscle, eye vessels, nerves, and revealed eyelids, lacrimal devices, conjunctiva and other eye appendages. 2) visual conduction path production: ① after the optic chiasm Zcm coronal resection part of the frontal lobe. ② in the left hemisphere, along the optic nerve, optic chiasm, optic tract, lateral geniculate body, optic nerve until the visual center for sequential anatomy to complete the visual display of the pathway. Removal of part of the brain tissue showed lentiform nuclei and the medial white matter within the capsule. ③ in the right hemisphere, 5cm away from the outer ear door at the level of horizontal cut, showing the inner capsule and the basal ganglia, and in the posterior lateral exposure of the optic nerve to the visual center. 3) Coloring, measuring plastic plexiglass package, routine preservation. 4) Experience: ① The specimen three-dimensional, complete display of visual and visual conduction path, but also shows the inner capsule, basal ganglia and other brain structures. ② left and right sides make up each other, both to maintain?
