Endodermal Derivatives of the 10 mm Pig Embryo (SEE IMAGE) Position your slides such that the spinal cord appears uppermost in the field. Bear in mind that the position of the endoderm structures in the 72-hour chick embryo is essentially similar to that of the structures in thethe pig embryo although at this time there is no more midgut and anterior posterior intestinal portals. Concentrate on the structures that are appearing for the first time in the pig. Digestive and Respiratory Systems First pharyngeal or hyomandibular pouch and furrow: In a frontal section passing through the pharynx, the auditory vesicle and the ventralmost part of the hindbrain, observe the first pharyngeal pouch, with its thick endoderm lining and the furrow in the thin ectoderm. Note if there is a closing plate. At the anterior border of the pouch and furrow is the first visceral or mandibular arch just like in the chick embryo. Find the future Eustachian tubes, derivatives or the first pouch. Second…
