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
|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
