Formation of the human digestive system, depicted at about (A) 16 days, (B) 18 days, (C) 22 days, and (D) 28 days. Digestive System Alimentary Canal develops from endoderm and splanchnic mesoderm

15.24 Formation of the human digestive system (Part 2)

Epi Ecto invaginates to meet endo to form Stomodeum & Proctodeum A septum separates the cloaca into anus (dorsal) and urogenital (ventral

Branchial Apparatus: the pharynx forms cavity within arches. Arch (mesoderm), Groove (epi ecto), Pouch (endo)

15.25 Formation of glandular primordia from the pharyngeal pouches (Part 1) Branchial Apparatus Arch (mesoderm), Groove (epi ecto), Pouch (endo) The fate of the pharyngeal pouches: 1st forms the external auditory passages

15.24 Formation of the human digestive system (Part 3)

Digestive System Alimentary Canal develops from endoderm and splanchnic mesoderm four layers of the digestive tract - the mucosa (1), the submucosa (2), the muscularis (3), the serosa (4). Peritoneum - visceral vs parietal Mesentery )

Alimentary Canal and Association Organs Differentiation of associated organs at the level of the forming stomach occurs both dorsally (spleen) and ventrally (liver).

15.26 Regional specification of the gut endoderm and splanchnic mesoderm through reciprocal interactions (Part 1)
