BACKGROUND
The robust brown capuchin monkey (Sapajus apella) is a South American primate with preferences for arboreal locomotion, which requires specific thoracic limb muscle adaptations. The present investigation studied the gross anatomy of the extrinsic and intrinsic scapular and brachial muscles.
METHODS
Gross dissections were performed in both thoracic limbs of four formaldehyde-fixed specimens.
RESULTS
Three rhomboideus muscles were present (capitis, cervicis, and thoracis). The trapezius muscle was divided into two parts (cervicis and thoracis). The pectoralis abdominalis and omotransversarius muscles were present. The anconeus muscle was found as an individual muscle or fused to the caput mediale of the triceps brachii muscle. The brachialis muscle had among one and two heads. The anconeus epitrochlearis was absent.
CONCLUSION
These muscles of Sapajus apella are adapted for arboreal locomotion and some terrestrial habits, since these have many similarities with other primates with a similar locomotor patterns.
背景
健壮的褐卷尾猴（Sapajus apella）是一种南美洲灵长类动物，偏好树栖运动，这需要特定的胸肢肌肉适应。本研究调查了肩胛和臂部外在及内在肌肉的大体解剖结构。
方法
对四个甲醛固定标本的双侧胸肢进行大体解剖。
结果
存在三块菱形肌（头、颈和胸）。斜方肌分为两部分（颈和胸）。存在胸腹肌和肩胛横突肌。肘肌可作为一块独立肌肉存在，或与肱三头肌内侧头融合。肱肌有一个或两个头。不存在肱肌滑车。
结论
褐卷尾猴的这些肌肉适应树栖运动和一些陆地习性，因为它们与其他具有类似运动模式的灵长类动物有许多相似之处。
