但假葉絳蟲雌雄兩性的生殖孔開口于體節(jié)中央的腹面。絳蟲沒有消化道，體表有許多絨毛，靠絨毛吸取腸道營養(yǎng)以供自身需要。生活習性編輯體壁結(jié)構(gòu) 絳蟲的體壁可分為兩層，即皮層(tegument)和皮下層。皮層是具有高度代謝活性的組織，其外表面具有無數(shù)微小的指狀胞質(zhì)突起，稱微毛(microthrix)，微毛結(jié)構(gòu)與腸絨毛很相似，只是它的末端呈尖棘狀。微毛遍被整個蟲體，包括吸盤表面。微毛下是較厚的具有大量空泡的胞質(zhì)區(qū)或稱基質(zhì)區(qū)，胞質(zhì)區(qū)下界有明顯的基膜(basal membrane)與皮下層截然分開，在接近基膜的胞質(zhì)區(qū)內(nèi)線粒體密集。整個皮層均無胞核(圖17-2)。皮下層主要由表層肌(superficial muscle)組成，有環(huán)肌、縱肌及少量斜肌，均為平滑肌。此肌層下的實質(zhì)組織中有大量的電子致密細胞或稱核周體(perikarya)，核周體通過若干連接小管穿過表絳蟲絳蟲層肌和基膜與皮層相連。核周體具有大的雙層膜的胞核和復雜的內(nèi)質(zhì)網(wǎng)，以及線粒體、蛋白類晶體和脂或糖原小滴等，所以皮層實際上是一種合胞體結(jié)構(gòu)，它靠核周體的分泌而更新。表層肌中的縱肌較強，它作為體壁內(nèi)層包繞著蟲體實質(zhì)和各并貫穿整個鏈體；但在節(jié)片成熟后，節(jié)片間的肌纖維會逐漸退化，因而孕節(jié)能自鏈體脫落。

The intra-node nature has been degraded. Only the uterus is fully developed and occupies the entire body section, containing many eggs. The gonads are mostly open to one or both sides of the somites, but the gonads of the female and male genitalia are open to the ventral surface of the somites. The worms have no digestive tract and there are many villi on the body surface. The villi absorb intestinal nutrients for their own needs. Living habits Edit the body wall structure Aphid body wall can be divided into two layers, namely the tegument and the subcutaneous layer. The cortex is a highly metabolically active tissue. Its outer surface has countless tiny finger-like cytoplasmic processes called microthrix. The microhair structure is similar to the intestinal villi except that it has a sharp spine at the end. Microhairs are covered by the entire body, including sucker surfaces. Under the micro-hairs, there is a thick cytoplasmic region or stromal region with a large number of vacuoles. The basal membrane in the lower boundary of the cytoplasmic region is distinct from the subcutaneous layer. The mitochondria are dense in the cytoplasmic region near the basement membrane. . No nucleus was found in the entire cortex (Figure 17-2). The subcutaneous layer is mainly composed of superficial muscles, including circular muscles, longitudinal muscles, and a small number of oblique muscles, all of which are smooth muscles. This submucosal parenchymal tissue contains a large number of electron-dense cells or perikarya. The perinuclear body is connected to the cortex through several connective tubules through the epidermis layer and the basement membrane. The perinuclear body has a large bilayer membrane nucleus and a complex endoplasmic reticulum, as well as mitochondria, protein crystals, and lipid or glycogen droplets, etc., so the cortex is actually a kind of syncytium structure, which depends on the perinuclear body. The secretion is updated. The longitudinal muscles in the superficial muscles are strong. They surround the body of the body and each of them penetrates through the entire body as the inner layer of the body wall. However, after the section matures, the intermuscular fibers gradually degenerate, and thus the energy-saving chain is Body shedding. There are many carbonate particles of calcium and magnesium scattered in the parenchyma of the aphid. The outer surface is oval with a cell membrane called calcareous body or calcium granule. It may have a buffering effect on the balance of pH and alkalinity. , Or as a library of ions and carbon dioxide. The nervous system includes the ganglia in the cranial stump and the six longitudinal nerve trunks it sends out. There are one main trunk and two auxiliary trunks on the left and right sides. They all run through the entire chain, and are also found in the head section and each section. There is a horizontal connection branch. The sensory terminals are distributed in the cortex and are connected to the tactile and aphid chelating chemoreceptors. The excretory system consists of several flame cells and four longitudinal drain pipes connected to it. The drainage pipe penetrates the chain body, with 2 on each side, and a thicker one near the ventral surface, and there is a horizontal branch at the back of each segment. In the first quarter, the drain pipe is more developed, often forming a drainage tube bundle.
