During the third week of embryological development there appears immediately behind the ventral ends of the two halves of the mandibular arch a rounded swelling named the tuberculum impar which was described by His as undergoing enlargement to form the buccal part of the tongue.More recent researches however show that this part of the tongue is mainly if not entirely developed from a pair of lateral swellings which rise from the inner surface of the mandibular arch and meet in the middle line.
