Morphological and histological observation on the digestive tract of Carcinoscorpius rotundicauda
-
摘要:
对圆尾鲎消化道进行形态学和组织学观察。消化道分为前肠(口腔、食道、嗉囊、砂囊)、中肠和后肠(直肠、肛门)。各部位上皮均为单层柱状上皮，除中肠外，均有几丁质层覆盖于腔面。口腔环肌为横纹肌，有大量腺体分布；食道环肌层不连续，纵肌数量少；嗉囊有腺体分布；砂囊环肌层连续，纵肌成束分散排列，有放射肌分布；肠道肌肉为横纹肌，肠腺发达，具2对肝胰腺导管；直肠环肌连续；肛门几丁质层中有许多腺体导管，在其表皮层之下的结缔组织中充满皮肤腺。
Abstract:The morphology and histology of digestive tract of Carcinoscorpius rotundicauda have been studied. The digestive tract of C. rotundicauda was divided into three parts: fore-gut(cavum buccale, oesophagus, craw and gizzard), mid-gut and hind-gut(rectum and anus). The fore-gut and hind-gut were lined with cuticle, which was lacking in the mid-gut. The circular muscle of cavum baccale belong in striated muscle, and there were a number of glands in the cavum baccale. The circular muscle of oesophageal was not continutive, and there were few longitudinal fibers in it. The gizzard was enclosed by a layer of circular muscle, and the longitudinal fibers were arranged in discrete bundles, and there were some radial muscles in the gizzard. There were a number of glands in the intestine wall, and two pairs of hepatopancreas tubes. The circular muscle of retum was continutive, and there were amount of glandular tubes in the layer of cuticle of anus. The connective tissue under the epithelium of anus was packed with glandula integumentaria.
