Theiler Stage 24 - Reposition of umbilical hernia

ts24_1

Fingers 2-5 are nearly parallel. Nail primordia are visible on the toes. The eyelids have fused in most cases by the end of the stage and the pinna almost completely covers the external auditory meatus. The umbilical hernia is disappearing and there is a corresponding increase in the size of the peritoneal sac.

Absent: fingers and toes joined together.
