- Ectodermal Derivatives of the 10 mm Pig Embryo Epidermis: This is a single layer of epidermal ectoderm cells covering the entire embryo. Nervous System Brain As in the 72- hour chick embryo, the first sections in the series, cut through the rhombencephalon due to the cranial flexure. Try to identify first all the major divisions of the pig brain. Myelencephalon: the part of the rhombencephalon tapering to the spinal cord. It has a roof of thin, non-nervous blood vesssels of the posterior choroid plexus and a large wide ventricle (IV) or the myelocoel. Metencephalon: the thick walled and thick roofed anterior part of the hindbrain. It gives rise to the cerebellum dorsally and the pons ventrally. Mesencephalon: the rounded region of the brain containing the mesocoel or the aqueduct of Sylvius. Diencephalon: By tracing the slides posteriorly, the mesencephalon gives way to the diencephalon, a laterally compressed region containing the third ventricle that communicates the telocoels of…Ectodermal Derivatives of the 10 mm Pig Embryo Epidermis: This is a single layer of epidermal ectoderm cells covering the entire embryo.

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.
