This study was a follow up to the study on the gross anatomy of the male agouti (Dasyprocta leporina) reproductive system. The seminal vesicles of the agouti are lobulated structures. The mean diameter of the large lumen is 883.6 +/- 76.83 microm. The mucosa (24.1 +/- 0.92 microm), which is lined by pseudo-stratified columnar epithelium is thrown into folds, which often branch. The lamina muscularis mucosa is thin and is made of loose connective tissue containing blood vessels. The mucosa of the leaf-like coagulating glands of the agouti is folded. The mean diameter of the lumen is 488.3 +/- 41.96 microm. The mucosa contains tubuloalveolar glands, which have a mean length of 199.5 +/- 28.83 microm. The thin epithelium, 15.0 +/- 1.25-microm wide, consists mostly of pseudo-stratified columnar cells. The epithelium also has surface modifications in the form of apical blebs and cilia. The epithelium of the agouti's lobulated prostate gland is also folded creating a large lumen with a mean diameter of 995.5 +/- 55.70 microm. The mucosa contains tubular and tubuloalveolar glands, each having a mean length of 134.4 +/- 13.59 microm. The epithelium (13.9 +/- 1.16 microm) consists of pseudo-stratified columnar cells. The pea-shaped bulbourethral gland (BG) of the agouti consists of convoluted tubular, mucous secretory units, which are irregularly shaped each with a mean length of 177.9 +/- 7.10 microm and a mean width of 63.5 +/- 3.97 microm. The BG of the agouti are ventro-lateral to the rectum and dorsally positioned to the pubic symphysis, and connected to the urethra by short ducts.
本研究是对雄性刺豚鼠(Dasyprocta leporina)生殖系统大体解剖学研究的后续。刺豚鼠的精囊是分叶状结构。大管腔的平均直径为883.6±76.83微米。黏膜(24.1±0.92微米)由假复层柱状上皮衬里,形成褶皱,且褶皱常分支。黏膜肌层很薄由含血管的疏松结缔组织构成。刺豚鼠叶状凝固腺的黏膜有褶皱。管腔平均直径为488.3±41.96微米。黏膜含有管泡状腺,平均长度为199.5±28.83微米。薄上皮宽15.0±1.25微米,主要由假复层柱状细胞组成。上皮还有顶端小泡和纤毛形式的表面修饰。刺豚鼠分叶状前列腺的上皮也有褶皱,形成平均直径为995.5±55.70微米的大管腔。黏膜含有管状和管泡状腺,每个平均长度为134.4±13.59微米。上皮(13.9±1.16微米)由假复层柱状细胞组成。刺豚鼠的豌豆形尿道球腺(BG)由盘曲的管状黏液分泌单位组成,形状不规则,每个平均长度为177.9±7.10微米,平均宽度为63.5±3.97微米。刺豚鼠的尿道球腺位于直肠腹侧、耻骨联合背侧,并通过短导管与尿道相连。
