Additional Information
Detailed Week by Week
The following information is a detailed timeline of embryonic development between week 3 to 8 and content does not form part of the current practical class.
Embryo Stages and Events
Day | Stage | Event |
Stage 7 | Primitive node (Hensen's node, primitive knot) The small circular region located at the cranial end of the primitive streak, where gastrulation occurs, and is a controller of this process. The second role is to act as an initial generator of the left-right (L-R) body axis. | |
Stage 8 | Neural neurogenesis, neural groove and folds are first seen | |
Stage 9 | Musculoskeletal somitogenesis - first somites form and continue to be added in sequence caudally
Neural - three main divisions of the brain, which are not cerebral vesicles, can be distinguished while the neural groove is still completely open
| |
Heart cardiogenesis - week 3 begins as paired heart tubes. |
