[Macroscopic anatomy of the human fetal thymus in the 2d half of uterine life].

The dissection under an operative microscope of 46 foetuses from a homogeneous series measuring 80 to 390 mm C-R (crown-rump) is the subject of a gross anatomic study of the thymus. The authors point out the size, the lobulation and connections with the vascular pedicles of the neck: the thyropericardeal sheet.
