There are about 4,000 tendons throughout the body.
This claim is echoed by a fair amount of websites but I couldn't find any decently trustworthy source.
Where can I find the list of all tendons in the human body?
I have only been able to find a list of skeletal muscles of the human body so far. I'm surprised that there are 4000 tendons even though they are only ~640 muscles: most muscles that I am aware of are attached to fewer than six tendons (FYI: Why some muscles have more tendons than others?).
