title: [Aponeurosis plantaris--phylogenetic development].
abstract: The plantar aponeurosis is differentiated in its most primitive form in Marsupialia, where it is formed by a single connective tissue strip, a continuation of the tendon of the m. plantaris. The tendon is usually not fixed to the calacaneal tuberosity. The lateral tract (fibular) of the plantar aponeurosis takes a distal course and forms processes for the first to fifth toe. (The number of inserting strips is different and variable in different species of marsupials). A separate medial (tibial) strip of the aponeurosis is lacking. 2. In Insectivora the plantar aponeurosis is differentiated similarly as in marsupials. Again the medial (tibial) strip of the aponeurosis is absent and the tendon of the m. plantaris is more firmly fixed to the calcaneus. Scandentia (Tupalia) have a two-layer aponeurosis. The fibular (lateral) layer is in continuation of the tendon of the m. plantaris, the medial (tibial) layer starts at the calcaneal tuberosity. The plantar aponeurosis of Tupalia does not yet form two separable tracts, however, the forming layers of the aponeurosis indicate the future separation of the uniform connective tissue plate. 3. In prosimians and simians a separate medial (tibial) tract develops which is independent on the tendon of the m. plantaris, and in anthropoids and humans gradually the planta predominates.
