摘要

Abstract >Bagrus Bayad (Forskal, 1775) is a bottom feeder fish feeds on different food items. Its oral cavity anatomy has many types of teeth adapted to the capacity and varieties of feeding. The aim of the present study was to use the gross anatomy and scanning electron microscopy to identify the anatomical characteristic, especially of the teeth and taste buds distributed on the roof and floor of the oropharyngeal cavity. The results clarified that Bagrus Bayad has two types of teeth; curved pointed and blunt teeth of different sizes. The teeth appeared on epithelial protrusions. The pharyngeal region had upper and lower pharyngeal teeth, the upper arranged into two oval prominences while the lower ones arranged into two triangular areas. The higher number of the pointed teeth is prove the carnivorous nature of the Bagrus Bayad. Three types of taste bud (I, II, & III) were found in the oropharyngeal cavity. The tongue present in the floor and free from teeth and characterized by the presence of taste bud type I and II. Many microridges of different arrangement observed on the surface epithelium of oropharyngeal cavity. The upper and lower valve characterized by the microridges, pores and taste buds. The knowledge of the nature of the oropharyngeal cavity of the Bagrus Bayad helps in identifying new and better methods for feeding in aquaculture. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract XMLNS =“http://www.wiley.com/namespaces/wiley”type =“main”> <title type =“main”>抽象</ title> > bagrus bayad（forskal，1775）是一个底部喂食器鱼在不同的食物上喂食。其口腔解剖学具有许多类型的牙齿，适应了饲养的能力和品种。本研究的目的是使用总解剖和扫描电子显微镜识别解剖学特征，尤其是牙齿和味蕾分布在口咽腔的屋顶和地板上。结果澄清了Bagrus Bayad有两种类型的牙齿;不同尺寸的弯曲尖的牙齿。牙齿出现在上皮突起上。咽部区域具有上下咽牙，上部布置成两个椭圆形突出，而下部排列成两个三角形区域。尖牙数量越多是蒲甘的肉食本质。在口咽腔中发现了三种类型的味蕾（I，II，＆amp; III）。舌头存在于地板上，没有牙齿，其特征在于味蕾类型I和II。在口咽腔的表面上皮上观察到不同布置的许多微粒。上下瓣膜以微粒，毛孔和味蕾为特征。 Bagrus Bayad的口咽腔的性质的知识有助于识别在水产养殖中喂养的新方法和更好的方法。</ p> </ abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" > 著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-24994/'>《Microscopy research and technique 》</a> <b style="margin: 0 2px;">|</b><span>2018年第8期</span><b style="margin: 0 2px;">|</b> <span>共9页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Alsafy Mohamed A.
