C5L Image Features
Gastrointestinal Tract
- Oesophagus is smaller while the trachea expands.
- Septum transversum ventral anchoring of attachment site is at the most cranial extension. This attachment now divides the intraembryonic coelom around the trachea into two canals, the L and R pleuro (pericardio-peritoneal) canals.
- Canals are lined by coelomic mesothelium and are continuous with whole I-E coelom (referred to hereafter simply as coelomic canals).
- Pleuroperitoneal fold on the medial side of the R common cardinal vein - this fold will form part of the diaphragm.

Gastrointestinal Tract Development
Smaller oesophagus, expanding trachea. Note ventral anchoring of attachment site is at the most cranial extension of the septum transversum. Note also that this attachment now divides the intraembryonic coelom around the trachea into two canals, the L and R pleuro (pericardio-peritoneal) canals. (Canals are lined by coelomic mesothelium and are continuous with whole I-E coelom - they will be referred to hereafter simply as coelomic canals). Note the pleuroperitoneal fold on the medial side of the R common cardinal vein - this fold will form part of the diaphragm.
About Stage 13 Embryo Sections - This image is from a serial section of a 6mm CRL pig embryo with some features of the Stage 14 embryo. This embryo is approximately equal to the day 42 human embryo. Use these serial images to identify internal features and relationships that exist within the embryo at this stage. Then compare these images with the later features of the Carnegie stage 22 human embryo.
