2 Testis 输出小管 睾丸网 生精小管 1)General structure 精小管 鞘膜脏层 ① Capsule 销膜腔 附睾管 a. tunica vaginalis vIsceral layer-serosa b tunica albuginea: thick, DCT /mediastinum testis: albuginea became thicker at posterior aspect /septum thin septa extend radiately from mediastinum testis to divided the parenchyma into lobule
2. Testis 1) General structure: ① Capsule: a. tunica vaginalis: visceral layer-serosa b. tunica albuginea: thick, DCT /mediastinum testis: albuginea became thicker at posterior aspect /septum: thin septa extend radiately from mediastinum testis to divided the parenchyma into lobule
② Lobule a. seminiferous tubule /highly coiled /30-70cm|ong,150-250 mm in d /begin as free blind end -run to posterior become into straight tubule(tubules rectus) enter mediastinum testis→rete testis→ efferent duct→→ connect With epididymal duct b. testicular interstitial tissue: lct between seminiferous tubule
