Key Events of Human Development during the seventh week (week 7) following fertilization or Clinical week 9 (LMP).
Timeline
| Event | ||
| Pancreas Week 7 to 20 pancreatic hormones secretion increases, small amount maternal insulin
Respire Week 7 - enlargement of liver stops descent of heart and lungs | ||
| Stage 18 | 
Limb bones form by endochondral ossification and throughout embryo replacement of cartilage with bone (week 5-12). Sense - Smell vomeronasal fibres and nervus terminalis[1] GIT - Liver obturation due to epithelial proliferation, bile ducts became reorganized, continuity between liver cells and gut [2] | |
|
GIT - Liver (stage 18 to 23) biliary ductules developed in periportal connective tissue produces ductal plates that receive biliary capillaries[4] | ||
| Stage 19 |  Neural accessory olivary nucleus appears [5]
