ANAL CANAL
APPENDIX (VERMIFORM APPENDIX)
-This is a narrow fingerlike evagination of the inferior end of the cecum. Histologically, it resembles the colon except that it has a smaller lumen, fewer and shorter crypts, many more lymphoid nodules, and no teniae coli.
-ANAL CANAL
-In humans, this canal is about 4 cm long and connects the rectum and the anal opening. The mucosa of the first 2 cm has typical colonic epithelium with very short crypts. This is replaced by stratified squamous epithelium, which continues to the anal opening.
