tuberosity
Skeletal attachment point
A tuberosity is a rounded projection or protuberance on a bone, typically where muscles or ligaments attach.
Anatomists use the term to describe specific landmarks: the *ischial tuberosity* (the sit bones), the *tibial tuberosity* (below the kneecap), the *deltoid tuberosity* (on the upper arm).
The word distinguishes these rough, knobby prominences from smoother bone surfaces.
