[Details of the muscular and nervous system in the anterior member of Sphenodon punctatus (reptiles-Rhynchocephales)].
Sphenodom is the only Lepidosaurian with an organisation of the nervous ways in the anterior member which constitute an important stage in tetrapod evoluation. Squamata are exceptions. The radial nerve is developed and possesses the most important part of the fibres for the dorsal muscles of the forearm. The flexor canal is separated into 2 voluminous trunks.
