Mouse embryo, Theiler stage 21.
Theiler Stage 21
Anterior footplate indented, marked pinna
- The distal borders of the anterior and posterior footplates are now indented and the digit widths and locations can be discerned.
- The 'elbow' and 'wrist' are now identifiable.
- The pinna rapidly develops and forms a crest at right angles to the head.
- Five rows of vibrissae are visible as well as a prominant hair follicle over the eye and another over the ear.
- The lens vesicle has lost its lumen.
- The physiological umbilical hernia is prominent. Absent: hair follicles, distally separate fingers.
- Embryonic age = 13 dpc (range 12.5-14)
- 52-55 somite pairs
- Equivalent Witschi Stage in rat = 29-30
- Equivalent Carnegie Stage in humans = 18-19
