Callithrix jacchus (common marmoset) is regularly used in biomedical research, including for studies involving the skeleton. To support these studies, skeletons of healthy animals that had been euthanized for reasons not interfering with skeletal anatomy were prepared. The marmoset dental formula 2I-1C-3P-2M of each oral quadrant is atypical for New World monkeys which commonly possess a third molar. Seven cervical, 12-13 thoracic, 7-6 lumbar, 2-3 sacral and 26-29 caudal vertebrae are present, the thoracolumbar region always comprising 19 vertebrae. A sigmoid clavicle connects the scapula with the manubrium of the sternum. Depending on the number of thoracic vertebrae, 4-5 sternebrae are located between the manubrium and xiphoid process. Wide interosseous spaces separate the radius from the ulna, and the tibia from the fibula. A small sesamoid bone is inserted in the m. abductor digiti primi longus at the medial border of the carpus, a pair of ovoid sesamoid bones is located at the palmar/plantar sides of the trochleae of each metapodial bone, and round fabellae articulate with the proximal surfaces of the femoral condyles. Male marmosets possess a small penile bone. Both the front and hind feet have five digits. The hallux possesses a flat nail, whereas all other digits present curved claws. Interestingly, a central bone is present in both the carpus and tarsus. This study provides a description and detailed illustrations of the skeleton of the common marmoset as an anatomical guide for further biomedical research.
食蟹猴（普通猕猴）常用于生物医学研究，包括骨骼方面的研究。为了支持这些研究，对因与骨骼解剖无关的原因而被安乐死的健康动物的骨骼进行了处理。每个口腔象限的食蟹猴的牙齿式为 2I-1C-3P-2M，这对于常见的具有第三磨牙的新世界猴来说是非典型的。有 7 个颈椎、12-13 个胸椎、7-6 个腰椎、2-3 个荐椎和 26-29 个尾椎，胸腰椎区域通常由 19 个椎骨组成。一个 S 形锁骨将肩胛骨与胸骨的胸骨柄连接起来。根据胸椎的数量，胸骨柄和剑突之间有 4-5 个胸骨。桡骨和尺骨之间有宽阔的骨间间隙，胫骨和腓骨之间也有宽阔的骨间间隙。腕骨的内侧缘有一个小的籽骨插入到第一跖骨长伸肌，每个跗跖骨的滑车的掌侧/跖侧有一对卵形籽骨，圆形的髌骨与股骨髁的近侧表面相接。雄性食蟹猴有一个小的阴茎骨。前脚和后脚都有五个脚趾。大脚趾有一个平的指甲，而其他所有的脚趾都有弯曲的爪子。有趣的是，腕骨和跗骨都有一个中央骨。本研究提供了普通猕猴骨骼的描述和详细插图，作为进一步生物医学研究的解剖学指南。
