Pulmonary Pleura at the Pseudoglandular and Canalicular Stages

Rough lung surface and pulmonary pleura at the pseudoglandular and canalicular phases. (Stain - Haematoxylin Eosin) Sagittal sections.

Panel A - left lung from a specimen at 9 weeks (39 mm crown-rump length CRL)

Panels B–D - right lung from a specimen at 10 weeks (56 mm CRL).

Panels C–E - higher magnification view of squares in panel B, respectively.


In panel A, outward growing bronchi provide small protrusions of the lateral or costal surface (arrows). A rough surface is also evident in the costal aspect in panel B, but a mesenchymal tissue (stars) is present beneath the thin pleura (E). Deep intersegmental veins do not reach the lung surface (arrowheads in B).

The canalicular phase of the bronchus was mixed with the pseudoglandular phase. upper, upper lobe; middle, middle lobe; lower, lower lobe; B6 and B8, sixth and eighth segmental bronchi; LLB, lower lobar bronchus; MLB, middle lobar bronchus; ULB, upper lobar bronchus.

Scale bars = 1 mm (A, B), 0.1 mm (C–E).
