Introduction
Draft Page - notice removed when complete.
How do you establish the anatomical axes of the embryo? Another well studied model of axis patterning is the establishment of limb axes, in particular this system historically was studied by grafting and rotating parts of the early developing limb.
Note there is some confusion arising in the terminology when comparing animal developmental axes and those of human anatomical axes.
- Developmental Mechanism - Dorsal-Ventral Axis first break in embryonic symmetry
- Developmental Mechanism - Rostro-Caudal Axis superior-inferior axis
- Developmental Mechanism - Left-Right Axis Nodal induces its own expression and that of Lefty, a Nodal feedback inhibitor with a longer diffusion range.
Axes Formation: Dorsal-Ventral Axis | Cranio-Caudal Axis | Left-Right Axis
