(三)被膜 (C) coating

1. 1. 白膜 Albuginea

包在睾丸实质的外面,为一层致密结缔组织膜。 Testicular parenchyma on the outside, and a layer of dense connective tissue membrane.

2. 2. 鞘膜 Hydrocele

白膜外面,分脏、壁两层。 Outside albuginea, sub dirty wall layers. 其间隙为鞘膜腔。 Its sheath gap cavity.

二、附睾 Second, the epididymis

附着于睾丸的上端和后缘,由十多条睾丸输出小管和一条附睾管构成。 Attached to the upper end and the trailing edge of the testicles, testicular output by more than a dozen epididymal tubules and a tube.

(一)分部 (A) Division  

附睾可分为附睾头、附睾体、附睾尾。 Can be divided into caput epididymis, epididymal body, epididymal tail.

(二)功能 (B) Function  

1. 1. 储存和输送精子。 Storage and transport sperm.

2. 2. 促进精子进一步成熟。 Promote further maturation of sperm.

三、输精管 Third, the vas deferens

起于附睾尾,经腹股沟管入盆腔,在膀胱底膨大为输精管壶腹,并与精囊腺的排泄管会合成射精管。 Starting at the tail of the epididymis, the inguinal canal into the pelvic cavity, at the bottom of the bladder enlargement of the vas deferens ampulla, seminal vesicles and the ejaculatory duct drainage tube will be synthesized. 全长约50cm。 Total length of about 50cm.

精索:为一柔软的圆索状结构,由输精管、睾丸动脉、蔓状静脉丛等被结缔组织包绕而成。 Spermatic cord: For a soft, round cord-like structure, the vas deferens, testicular artery, plexiform venous plexus surrounding connective tissue together.
