The agouti (Dasyprocta prymnolopha, Wagler 1831) is a wild rodent of great zootechnical potential, a fact that enables anatomical and morphological studies to support management actions with this animal. In this perspective, this study aimed to describe the anatomy and histology of the agouti stifle joint. Four adult agoutis were used, two females and two males. The animals were submitted to dissection and identification of the structures of the stifle joint. For light microscopy study, samples of the patellar ligament, cranial and caudal cruciate ligaments, medial and lateral collateral ligaments were used. Agouti has a highly congruent patellofemoral joint; elongated patella; medial and lateral fabellae at the proximal insertion of the gastrocnemius muscle; medial and lateral meniscus with lunula; in addition to the presence of the following ligament structures: patellar ligament, cranial and caudal cruciate ligaments, medial and lateral collateral ligaments, meniscofemoral ligament, caudal meniscal ligament of the medial meniscus, and medial and lateral cranial ligaments. The patellar ligament presents bundles of parallel collagen fibers with a straight path and coated fibroblasts; collateral and cruciate ligaments had loose and dense connective tissue, coated fibroblasts and collagen bundle undulations, the latter most expressive in the caudal cruciate ligament. Thus, except for the shape and angulation of the stifle, which allows specific movements, the agouti stifle has structures analogous to that of other rodents and domestic animals.

刺鼠膝关节的形态学(Dasyprocta prymnolopha,Wagler 1831)

刺鼠 ( Dasyprocta prymnolopha), Wagler 1831) 是一种具有巨大畜牧业潜力的野生啮齿动物,这一事实使解剖学和形态学研究能够支持对这种动物的管理行动。从这个角度来看,本研究旨在描述刺鼠膝关节的解剖学和组织学。使用了四只成年刺鼠,两雌两雄。对动物进行膝关节结构的解剖和鉴定。对于光学显微镜研究,使用了髌韧带、颅骨和尾部十字韧带、内侧和外侧副韧带的样本。Agouti 具有高度一致的髌股关节;拉长的髌骨;腓肠肌近端插入处的内侧和外侧腓骨;带有月牙的内侧和外侧半月板;除了存在以下韧带结构外:髌韧带、颅骨和尾十字韧带、内侧和外侧副韧带、半月板韧带、内侧半月板的尾半月板韧带以及内侧和外侧颅韧带。髌韧带呈现出平行的胶原纤维束,具有笔直的路径和包被的成纤维细胞;侧副韧带和十字韧带有疏松而致密的结缔组织、包被的成纤维细胞和胶原束的起伏,后者在尾十字韧带中表现最为明显。因此,除了允许特定运动的膝关节的形状和角度之外,刺鼠膝关节具有类似于其他啮齿动物和家畜的结构。以及内侧和外侧颅韧带。髌韧带呈现出平行的胶原纤维束,具有笔直的路径和包被的成纤维细胞;侧副韧带和十字韧带有疏松而致密的结缔组织、包被的成纤维细胞和胶原束的起伏,后者在尾十字韧带中表现最为明显。因此,除了允许特定运动的膝关节的形状和角度之外,刺鼠膝关节具有类似于其他啮齿动物和家畜的结构。以及内侧和外侧颅韧带。髌韧带呈现出平行的胶原纤维束,具有笔直的路径和包被的成纤维细胞;侧副韧带和十字韧带有疏松而致密的结缔组织、包被的成纤维细胞和胶原束的起伏,后者在尾十字韧带中表现最为明显。因此,除了允许特定运动的膝关节的形状和角度之外,刺鼠膝关节具有类似于其他啮齿动物和家畜的结构。
