Gross and microscopic study of Cercopithecus aethiops pygerythrus and Papio cyanocephalus anubis shows that these cercopithecines have a quadriceps tendon the distal portion of which consists mostly of dense collagenous bundles with scattered fine elastic fibres most of which lie in the loose connective tissue planes within and around the tendon and around blood vessels. A distinct fibrovesicular structure, the suprapatella, lies within the tendon of the vastus intermedius above the pony patella. Histologically, this structure is characterised by interwoven bundles of collagenous fibres, among which are enmeshed large cells containing prominent nuclei surrounded by large clear spaces. It is postulated that this structure facilitates hyperflexion of the knee during the initial phases of springing and jumping.
对东非长尾猴（Cercopithecus aethiops pygerythrus）和东非狒狒（Papio cyanocephalus anubis）的大体和微观研究表明，这些猕猴科动物的股四头肌肌腱远端部分主要由致密的胶原束组成，伴有散在的细弹性纤维，其中大部分位于肌腱内部和周围以及血管周围的疏松结缔组织平面内。一个独特的纤维囊状结构，即髌上结构，位于中间肌肌腱内髌骨上方。从组织学上看，该结构的特征是胶原纤维束相互交织，其中包埋着大细胞，这些大细胞含有突出的细胞核，周围有大的透明间隙。据推测，这种结构在弹跳和跳跃的初始阶段有助于膝关节的过度屈曲。
