title: The development of Meckel's cartilage in staged human embryos during the 5th week.
abstract: The study was conducted on 15 embryos aged 5 weeks. The primordium of Meckel's cartilage appears at stage 13 (32 days) as a rounded structure composed of fusiform and polygonal cells, which blend with other cells of the mandibular process. At stages 14 and 15 (33 and 36 days) Meckel's cartilage forms a well delineated core of small densely packed cells.
