Taxonomic definition
Taxonomic definition An extensor expansion is an aponeurosis [aponeurosis ] which acts on the pectoral girdle [superficies divisionis atrii sinistri ] excluding the free upper limb [pars libera membri superioris ].
Notes
The aponeurosis extensoria and its components were described by Landsmeer (1949 Anat Rec 104:31-44; 1955 Acta Anat 25, Suppl 24:1-69). The extensor hood is the proximal portion of the extensor expansion, covering the MP joint and extending onto the proximal phalanx. The central band of fibres of the extensor expansion attaches to the middle phalanx, whereas the collateral bands attach to the distal phalanx.
