Jaw Apparatus and Feeding Mechanics of Typhlops (Ophidia: Typhlopidae): a Reconsideration

Nikolai N. Iordansky

Abstract


The cranial kinesis and movements of the lower jaw in Typhlops are analyzed, with special emphasis placed on the functions of the jugomandibular ligament. The musculature of the Typhlops jaw apparatus is described. The role of movements of the quadrato-mandibular and palato-maxillary systems in feeding mechanics and functioning of the jaw apparatus muscles is discussed.


Keywords
