报告主题：脾 主题属性：自选 标本号：14# 材料：猫脾脏切片 染色：HE染色
教学要求：掌握脾脏的组织结构及其判断依据。
脾索
Splenic cord 脾窦
Splenic sinusoid 中央动脉 Central artery 白髓
White pulp 边缘区
Marginal zone

Figure 13 spleen (cat splenic slices, HE stained, 10 x 10)
脾脏分为白髓、边缘区和红髓，脾内无淋巴窦，而有许多血窦。白髓在新鲜脾的切面上呈散在的白色点状，它是由密集的淋巴细胞组成，沿中央动脉周围分布。白髓分为动脉周围淋巴鞘和淋巴小结两部分。红髓位于被膜下、小梁周围及白髓之间，红髓可分为脾索和脾窦。边缘区位于红髓和白髓的交界处，是脾首先接触抗原并引起免疫应答的重要部位。 The spleen is divided into white pulp, edge area and the red pulp, and there is no lymphatic sinus in the spleen, and there are a lot of blood sinus. Fresh white pulp in spleen is scattered white dot in cross section, which is composed of dense lymphoid cells, distributed around the central artery. White pulp is divided into lymphatic sheath surrounding arteries and the lymph nodule. Red pulp, trabecular located under the capsule around and between white pulp, red pulp can be divided into the spleen and splenic sinus. Fringe area, which lies at the intersection of red pulp and white pulp, spleen is the first contact antigen and lead to an important parts of the immune response.

报告主题：肾上腺 主题属性：自选 标本号：34# 材料：人肾上腺切片 染色：HE染色
教学要求：掌握肾上腺的组织结构及其判断依据。
被膜 Envelope 球状带
Zonaglomerulosa 束状带
Zonafasciculata 网状带
Zonareticularis 髓质 Medulla 中央静脉
Central venous
图14 肾上腺（人肾上腺切片，HE染色，10×10） Figure 14 adrenal (adrenal slices, HE stained, 10 x 10)
低倍镜下，可见肾上腺的被膜、皮质和髓质。被膜为致密薄层结缔组织，包于肾上腺的表面，极少伸入腺实质中。皮质有外向内可分为球状带、束状带和网状带。髓质呈蓝紫色，位于皮质的深部，范围比较狭小，主要由排列成索状或团块状的髓质细胞组成，其间有血窦和少量结缔组织。髓质中央可见由较大的中央静脉。
At low magnification, visible, cortex and medulla of adrenal capsule.For dense thin layer of connective tissue capsule, package on the surface of the adrenal gland, rarely into glandular substance. Leather can be divided into zona inside extroversion, zonafasciculata, and zonareticularis. Medulla is violet, is located in the cortex of the deep, narrow range, mainly by the arranged in funicular or crumb of medulla cells, there is blood sinus and small amounts of connective tissue. Medulla central visible by the large central vein.

实验十五 女性生殖系统
报告主题：次级卵泡 主题属性：自选 标本号：44# 材料：猫卵巢切片 染色：HE染色
教学要求：掌握次级卵泡组织结构。
卵泡腔
Follicular cavity 初级卵母细胞 Primary oocyte 卵丘
Cumulus oophous 颗粒层
Stratum granulosum 卵泡膜
Follicular theca 原始卵泡
Primordial follicle
图15 次级卵泡（猫卵巢切片，HE染色，10×10）
Figure 15 secondary ovarian follicles (cats ovaries slices, HE stained, 10 x 10)
次级卵泡位于皮质深部。低倍镜下可见次级卵母细胞体积大，透明带明显，卵泡细胞微多层，较小的次级卵母细胞有许多小的卵泡腔，较大的次级卵母细胞有一个较大的卵泡腔，内含卵泡液，并可见卵丘、放射冠、颗粒层等结构。卵泡膜此时已分为两层，内层细胞多，纤维少，血管丰富，外层反之，卵泡膜内层细胞称为膜细胞。卵泡膜外层靠近周围的结缔组织，与其无明显分界。
Secondary ovarian follicles in the deep cortex. At low magnification is secondary oocytes volume is large, transparent clear, follicular cell layers, smaller secondary oocytes there are many small follicular cavity, large secondary oocytes had a larger follicular cavities, contain follicular fluid, mound, corona radiata and visible eggs, such as granular layer structure. Theca now divided into two layers, the inner cells, less fiber, rich blood vessels, outer layer on the other hand, the theca lining cells called membrane. Theca outer layer near the surrounding connective tissue, and no obvious boundaries.
