Appendix
Make it clearer
The vermiform appendix is a diverticulum of the cecum: a diverticulum is an outpouching that extends off the wall, and this one in particular is hollow and shaped like a tube, which is why it is called tubular. It arises from the wall of the cecum, and not from just any point on it, but from the back surface and toward the middle, what medicine calls posteromedial. It is a true diverticulum, not just a dent in the wall.
It helps to picture the sleeve coming off the body of a shirt: it is continuous with the garment, hollow inside, and it projects outward. What is not fixed is where the tip of that sleeve ends up. In one person it points one way, in another it points somewhere else, and that variability is normal for the appendix.
In brief
The vermiform appendix is a true tubular diverticulum arising from the posteromedial wall of the cecum, that is, a hollow, tube-shaped extension of that wall.
The position of the appendix's tip varies.
The base arises from the cecum, while the tip can point in different directions.
