Abstract:
The villi of the caecal mucosa in postnatal rats were studied using both scanning electron and light microscopy. On the day of birth, numerous villi of various sizes and shapes were present on the caecal mucosa. After the 5th day, the villi decreased very rapidly in length and in number. A strong constriction was observed at the basal region of the caecal villi. During postnatal days 5 approximately 9 the villi probably separated and disappeared from the caecal mucosa. No villi were observed in rats that were over 10 days of age.
