This Embryology category shows pages and media related to mouse embryonic day 13.5 (E13.5) of development. This staging by "days" relate to in the female presence of a vaginal plug indicating that the mating occurred, see timed pregnancy.

Events

  • Musculoskeletal System - Abdominal wall all five the principal muscles observed (rectus abdominis, external oblique, internal oblique, transversus abdominis, and panniculus carnosus). Rectus abdominis not completely segregated from the transversus abdominis and obliques. The panniculus carnosus was formed in the dorsal half of the abdominal wall adjacent to the skin. The myoblasts have migrated approximately three fourths of the distance to the ventral midline. Connective tissue between the muscle layers and dermis comprised the majority of the thickness of the secondary abdominal wall with the layer between the panniculus carnosus and external oblique being the thickest of these layers (470 μm). Directional organization of the myoblasts in the external oblique, internal oblique, and transverses abdominis.[1]
  • Taste - Pax9 expression in tongue circumvallate papilla and foliate papillae Image | Pax
  • Pancreas - day 13 to 14 (E13, E13.5, E14) stomach rotation brings the smaller ventral pancreatic bud dorsally to fuse with the larger dorsal pancreatic bud.
