一、宫颈的解剖组织学宫颈分两部分,即宫颈阴道部和子宫颈管。与宫颈阴道部相接的阴道部分形成穹窿。宫颈前为膀胱,后壁披以腹膜作为子宫直肠窝的前壁,被两侧的主韧带和宫骶韧带所固定。宫颈管为梭形,长约2.5—3厘米,上端为宫颈内口与宫腔相连,下端为富颈外口。宫颈管粘膜有纵行与斜行的皱壁,其间有单一的或分成两枝的裂隙(即腺体);其壁光滑,深度多在3毫米以内。炎症、内分泌等病理变化时,可使裂隙向宫颈深处延伸或裂隙变得复杂。宫颈阴道部和阴道都披以复层鳞状上皮。生育年龄分为三层。(一)基底层(即生发层):由1或2层小立方上皮构成,排列整齐,核卵圆形,含丰
First, the anatomy of the cervix The cervix is divided into two parts, namely the cervix vagina and cervix. Vaginal part of the cervix and vagina to form a vault. Cervical anterior bladder, posterior wall draped of the peritoneum as the anterior wall of the uterine rectum, was fixed on both sides of the main ligament and uterosacral ligaments. Cervical tube fusiform, about 2.5-3 cm, the upper end of the cervix connected to the uterine cavity, the bottom of the neck for the rich neck. Cervical mucosa with longitudinal and oblique fold wall, during which there is a single or divided into two branches of the fissure (ie, gland); its wall is smooth, more than 3 mm in depth. Inflammation, endocrine and other pathological changes, the cracks can extend to the depths of the cervix or cracks become complicated. Cervix vagina and vagina are covered with stratified squamous epithelium. Childbearing age is divided into three layers. (A) the basal layer (ie germinal layer): by 1 or 2 layers of small cubic epithelium, arranged in neat rows, oval nucleus, abundance
