对恒河猴、食蟹猕猴、短尾短尾猴、猪尾短尾猴、恒河猴、食蟹猴、短尾短尾猴、短尾猴、恒河猴、食蟹猴、短尾猴、猪尾猴、恒河猴、恒河猴、对恒河猴和恒河猴子宫颈腔内、隐窝和裂隙内精子和白细胞的分布进行了研究。恒河猴、恒河猴、恒河猴和短尾猴的颈管是直的或略有弯曲。恒河猴、食蟹猕猴和猪尾猕猴不同发育的腹侧和背侧小丘的存在，导致颈椎管的背侧腹曲。所有被调查的标本的宫颈基本上都是纤维组织，向子宫体方向肌纤维的数量增加。恒河猴、恒河猴和恒河猴的颈部粘膜含有大量的裂隙和管状通道，其结构、长度、宽度、方向和分支程度各不相同。猕猴颈部粘膜含有大量结构复杂、长度、宽度和分支程度复杂的隐窝。猕猴的宫颈隐窝通常在宫颈外较长，而在宫颈中段，粘膜含有小的隐窝、裂隙和长的隧道。在恒河猴、食蟹猴和猪尾猴中，鳞状-柱状交界处位于外口附近。在松鼠猴中，鳞状上皮连续穿过外口，覆盖在前庭和颈丘的外表面。短尾猴的鳞状柱状交界处位于阴道内，距宫颈外口1-3 cm。在鳞状柱状交界处和宫颈外口之间的阴道壁上覆盖着大量分枝的粘膜和柱状上皮。宫颈上皮纤毛细胞占9%~19%。在宫颈粘膜的隐窝和裂隙内发现了大量的精子和相对较少的白细胞。研究结果与宫颈在周期的不同阶段、怀孕和分娩期间的功能有关。
The uterine cervix of rhesus macaque, crab-eating macaque, stump-tailed macaque, pig-tailed macaque, marmoset, baboon, patas, and squirrel monkeys was studied macroscopically and microscopically. Distribution of spermatozoa and leukocytes in the lumen and within the crypts and clefts was studied in rhesus and marmoset uterine cervix. The cervical canal of baboon, patas, marmoset, and stump-tailed monkeys is straight or slightly bent. The presence of variably developed ventral and dorsal colliculi in rhesus, crab-eating, and pig-tailed macaques causes the dorsoventral sinuosity of the cervical canal. The cervix of all investigated specimens is fundamentally fibrous tissue and the amount of muscle fibers increases toward the uterine corpus. The cervical mucosa of baboon, marmoset, and patas monkeys contains a large amount of clefts and tubular tunnels of variable structure, length, width, direction, and degree of branching. The cervical mucosa of macaques contains a large number of crypts of complex structure, length, width and degree of branching. The cervical crypts in macaques are usually longer in the ectocervix; whereas, in the midcervix, mucosa contains small crypts, clefts and long tunnels. Squamo-columnar junction is located near the external os in baboon, patas, marmoset, rhesus, crab-eating, and pig-tailed monkeys. In squirrel monkey, squamous epithelium is continuous through the external os, covers the vestibule and external surface of the cervical colliculi. In stump-tailed macaque, squamo columnar junction is located in the vagina, 1–3 cm from the external os of the cervix. The vaginal wall between the squamo-columnar junction and the external os of the cervix is covered with heavily branched mucosa lined with columnar epithelium. Ciliated cells of cervical epithelium occur in 9 to 19%. A large number of spermatozoa and a relatively low number of leucocytes have been found within crypts and clefts of cervical mucosa. The results are discussed in relation to the function of the cervix in different stages of the cycle, during pregnancy and parturition.
