Appendix
The appendix is a fingerlike appendage on the first portion of the large intestine. Like the large intestine, it also has straight intestinal glands and lacks villi. Abundant lymphoid tissue, both diffuse and nodular, occupies much of the lamina propria. Unlike the remainder of the large intestine, the appendix has a complete outer longitudinal muscle layer, thus lacking taeniae coli. The appendix is covered by a serosa. 100x
