I followed the question posting process, and at the end saw that it posted 2 questions:
- Does any tendon in humans receive a high amount of blood supply? Or is the property of not receiving a large blood supply a constant across tendons?
- https://biology.stackexchange.com/q/97790/630 [removed because it is a duplicate question]
I don't know how to reproduce. Rare, but not the first time this happened with me.
