双峰驼跖趾关节解剖结构   总被引:3,自引:0,他引:3  
采用大体解剖学方法,研究了成年双峰驼的8个跖趾关节,并与马、牛、羊、猪、犬等动物的对等器官进行了比较。结果发现,双峰驼跖趾关节的形态结构有以下显著特征:(1)跖骨远端关节面后部有矢状嵴,近趾节骨近端关节面后部有与之相对应的矢状沟,这种结构与跖行动物和趾行动物相类似;(2)籽骨上没有对应近趾节骨近端的关节面;(3)籽骨间韧带只连接同一趾上的2个籽骨,与牛的将2趾的4个近籽骨连在一起的结构不同;(4)轴侧侧副韧带不像牛的那样与对侧的同名韧带共同起始于跖骨远端滑车间切迹,而是分别起始于此切迹的轴侧韧带窝及韧带结节;(5)轴侧侧副韧带仅为1层,而远轴侧侧副韧带分为2层;(6)籽骨直韧带、趾间趾节骨籽骨韧带及趾间近韧带均缺如。  相似文献

本研究用解剖学和组织学方法首次确定我国双峰驼具有血淋巴结这一形态结构。其外观呈卵圆形、紫红色,直径6-11mm,常见于皮下结缔组织中。在组织学上,外有一层由胶原纤维、弹性纤维和成纤维细胞构成的薄而疏松的被膜,其中有较多的血管和淋巴管;被膜伸入内部形成细小且分布散乱的小梁,但未将实质分隔成明显的小叶。实质由大量的血窦、较少的淋巴小结和淋巴窦构成,未见索状淋巴组织。血窦可分为边缘窦和中间窦,充满血液,前者位于被膜下方,较宽大,呈索状排列;后者狭窄,吻合成网;窦壁由内皮和基膜组成。淋巴窦较少,窦壁完整,明显扩张。淋巴小结多呈卵圆形,散在分布于血窦之间,由淋巴、网状组织构成,有的有明显的的生发中心。和他种动物相比,双峰驼血淋巴结在组织学上有以下特点:(1)除具有血管和血窦外,还有淋巴管和淋巴窦;(2)实质无皮质和髓质之分;(3)淋巴组织主要为淋巴小结,未见索状的淋巴组织。  相似文献

双峰驼诱导排卵因子结构的研究   总被引:3,自引:2,他引:3  
应用岛津紫外分光光度计系统地扫描并记录了公驼精清,各活性组分以及诱导排卵因子的紫外吸收光谱。扫描结果证明:公驼诱导排卵因子(OIF)在精清内相对稳定的原因,是OIF在精清内由多层分子量不同、性质各异的蛋白质所包裹,从而证明了我们以前的推测。  相似文献

应用组织学方法观察了雌性空怀双峰驼生殖道的形态结构。结果显示,双峰驼生殖道的基本结构与其他哺乳动物相似,但微细结构有差异。双峰驼输卵管粘膜皱襞极其发达,分支多而呈复杂的网状迷路。皱襞基部的迷路酷似固有膜而存在腺体,迷路网格内常见细胞团块。虽然双峰驼怀孕时胎儿位于左侧子宫角,但左、右子宫角以及子宫体的组织结构基本相同。子宫内膜无肉阜,上皮下陷于固有膜内,形成大量长而弯曲的单管状腺。子宫颈固有膜浅层分布有许多小腺体,深层分布有成群的较大腺体。这些腺体为分支管状腺,腺上皮PAS强阳性。阴道粘膜上皮为复层上皮。从输卵管到阴道,粘膜上皮主要为单层柱状上皮,由纤毛细胞和分泌细胞组成,局部可见假复层柱状纤毛上皮。纤毛细胞由前向后逐渐减少,但在子宫颈仍可见到。粘膜上皮和腺上皮内夹有许多淋巴细胞或中性粒细胞,后段局部甚至见到这些免疫细胞浸润于上皮细胞间。固有膜内分布有大量淋巴细胞、中性粒细胞、肥大细胞、浆细胞和巨噬细胞,有时出现淋巴滤泡。  相似文献

The arterial supply of the six carpal joints was studied in Bactrian camels. The arterial branches supplying the carpal joints were the proximal medial dorsal, middle medial dorsal, distal medial dorsal, proximal lateral dorsal, distal lateral dorsal, proximal medial palmar, distal medial palmar, lateral palmar, proximal palmar and dorsal palmar carpi and the dorsal interosseous antebrachium branches. Some small unnamed branches supplied the diverticulum and the antebrachiocarpal joint capsule. All these arteries arose from the lateral and medial branches of the radial artery.  相似文献

A 15‐year‐old male dromedary camel with a history of chronic severe keratoconjunctivitis and corneal mass in the left eye of 6 months’ duration was referred to the Veterinary Medical Teaching Hospital at Adnan Menderes University. A superficial keratectomy was performed and biopsy material submitted for histopathology. The diagnosis was corneal papilloma. There has been no recurrence of the neoplasm to date (6 months, 1 year). Corneal papilloma has not been reported previously in camels and seems to be associated with papillomavirus.  相似文献

应用大体解剖学和血管铸型方法,研究了12峰双峰驼肾动脉的分支分布。结果显示,肾脏的肾动脉在进入肾门之前均分成一背干和一腹干,在肾窦内,背干分为一前支,再由前、后支分别发出背部贤脏的各肾段动脉。腹干不分前、后支,而由主干直接发出腹部肾脏的各肾段动脉。不仅各肾段动脉之间未见吻合,背干及其分支与腹干及其分支之间也无吻合。左肾肾段动脉共13条,右肾肾段动脉12条。表明,双峰驼不仅左、右肾的肾动脉与肾段动脉不尽相同,各肾的背部和腹部的动脉供应也存在差异。肾动脉的背干和腹干是相对独立的。  相似文献

The arterial supply of the six cubital joints from bactrian camels was studied. There were 15 arterial branches supplying the joint. The branches that arose from the transverse cubital artery were the medial anterior, superior anterior, lateral anterior, middle anterior, inferior anterior, superior lateral, middle lateral, inferior lateral, superior posterior and superior lateral posterior cubital branches. The branches originating from the collateral ulnar artery were the medial, middle posterior, inferior posterior, medial posterior and inferior lateral posterior cubital branches. These arteries united with each other around the cubital joint.  相似文献

The Arterial Supply to the Eye of the Bactrian Camel (Camelus bactrianus)   总被引:1,自引:0,他引:1  
The arterial supply to the eye of the bactrian camel (Camelus bactrianus) was studied by gross dissection. The supply came from the external ophthalmic, external ethmoidal and malar and maxillary tubercular arteries, ophthalmic rete mirabile, and the rostral epidural rete mirabile. The external ophthalmic artery gave rise to branches to supply the dorsal oblique muscle, lacrimal gland, superior and inferior eyelids, and the lateral angle of the eye, and to take part in the formation of the rostral epidural rete and the ophthalmic rete mirabile. The external ethmoidal artery detached off some branches to supply the ventral and medial dorsal rectus oblique muscles, the conjunctiva of the superior eyelid and the fat body of the orbit. The branches of the malar artery supplied the inferior, superior and third eyelids, ventral oblique muscle, and the medial angle of the eye. The ophthalmic rete mirabile gave off many branches to supply the rectus muscles of the eye, dorsal oblique and retractor oculi muscles, levator muscle of the superior eyelid, and the choroid.  相似文献

The arterial supply of the six metacarpophalangeal joints was studied in Bactrian camels. The arterial branches supplying the metacarpophalangeal joints were derived from the metacarpal distal perforating, medial and lateral branches of the palmar metacarpal artery III, medial and lateral branches of the palmar common digital artery III and the abaxial palmar proper digital arteries III and IV. These arterial branches were the proximal dorsoaxial distal metacarpal, distal dorsoaxial distal metacarpal, abaxial distal metacarpal, palmar distal metacarpal, interosseous distal metacarpal, dorsoaxial proximal proximal phalangeal, palmoaxial proximal proximal phalangeal, palmoabaxial proximal proximal phalangeal and dorsoabaxial proximal proximal phalangeal branches. They linked with each other around the metacarpophalangeal joint.  相似文献

双峰驼水代谢与血液中无机离子浓度的动态关系   总被引:5,自引:1,他引:5  
对双峰驼禁水15d,于禁水前、后及暴饮后采血,测定其血液中多种无机离子的浓度变化。结果表明,全血碳酸氢盐含量在禁水期变化极显著,与禁水前相比,冬季试验升高28.09%,夏季试验升高26.59%;暴饮后快速下降,冬、夏季试验分别比禁水前低9.5%和7.8%,4d后恢复正常。血清中K+和Fe2+含量未见统计学差异。血清中Na+、Cl-、Ca2+、Mg2+、和P3+的含量于禁水期逐渐上升,暴饮后快速下降,其变化均有显著差异,其中Na+的正常值显著高于其他反刍动物。结果表明,双峰驼在禁水期具有较高的血液渗透压和碱储量,其对保证缺水时血液酸碱平衡的调节,维持血容量,保证机体正常水代谢功能具有重要作用,是骆驼耐干渴的重要原因之一。  相似文献
