Longitudinal growth of the lateral pterygoid muscle in human fetuses.
The length of the upper and lower heads of the lateral pterygoid muscle was estimated in 44 fetuses aged 9 to 35 weeks. The lower head of the muscle is always longer than the upper one. Intensive increase in the length of the muscle is observed between 11th and 20th week.
