对12只福尔马林固定的鸵鸟进行了解剖，对骨盆、股骨、胫颧骨、踝跖骨和指骨区域的肌肉和肌腱进行了解剖描述。在鸵鸟的盆肢上，可以确定36块肌肉。鸵鸟缺乏第一和第二个脚趾的肌肉(拇指屈肌除外)，这种肌肉可以在有四个脚趾的鸟类中找到。嗯。在其他鸟类中存在的髂粗隆中肌、足底肌、趾四伸肌和趾内收肌也不存在，而mm。鸵鸟的胸肌和副股骨肌多见。腓肠肌上内侧部是腓肠肌的肌腱部分。股外侧屈肌和股内侧屈肌通过筋膜片插入。髂腓肌的尾侧部分终止于股浅筋膜的尾侧。Mm的尾部头部。指III屈肌、指IV屈肌和拇长屈肌在股骨的月国窝处有共同的起源。指IV屈肌外侧头和指III屈肌穿通肌的股骨头起始于指III屈肌头外侧起始处。此外，最后命名的肌腱与环指肌止点腱融合。指三伸肌起源于踝间关节背侧关节囊的板状筋膜片部分。
Dissections of 12 formalin-fixed ostriches were performed to give anatomical descriptions of the muscles and tendons of the pelvic, femoral, tibiotarsal, tarsometatarsal and digital regions. In the pelvic limb of the ostrich, 36 muscles can be determined. The ostrich lacks those muscles to the first and second toes (with exception of the M. flexor hallucis tongus), which can be found in birds with four toes. The Mm. iliotrochantericus medius, plantaris, extensor proprius digiti IV and adductor digiti IV, which are present in other birds, are also absent, whereas the Mm. pectineus and femorotibialis accessorius additionally occur in the ostrich. The Pars supramedialis is a tendineous part of the M. gastrocnemius, on which the Mm. flexor cruris lateralis and flexor cruris medialis insert by means of a fascial sheet. The caudal part of the M. iliofibularis terminates within the caudal aspect of the superficial fascia cruris. The caudal heads of the Mm. flexor perforatus digiti III and flexor perforatus digiti IV as well as the M. flexor hallucis longus have a common origin on the Fossa poplitea of the femur. The lateral head of the M. flexor perforatus digiti IV and the femoral head of the M. flexor perforans et perforatus digiti III originate on the tendon of origin of the Caput laterale of the M. flexor perforatus digiti III. Furthermore, the last named tendon fuses with the tendon of insertion of the M. ambiens. The M. extensor proprius digiti III originates on a plate-like fascial sheet part of the dorsal joint capsule of the intertarsal joint.
