Where does this come from, and can I check it?

Golgi tendon organs sit at the muscle-tendon junction and report tension. The figure is taken from NCBI Bookshelf, which is linked in full on this page. Every fact on Mondo Knows names its source rather than repeating an unsourced claim.

Is this really a human body fact?

Yes. It sits on the Human Body shelf, one of 2,600 sourced facts grouped into space, animals, the human body, history, science and more. Category pages collect every fact in the same field.

Mondo Knows Facts

Sensors in tendons measure how hard a muscle pulls

Golgi tendon organs sit at the muscle-tendon junction and report tension These encapsulated nerve endings weave between collagen fibres of the tendon. They fire when the tendon is stretched by muscle contraction, giving the brain precise feedback about force rather than length. Their signals also feed a reflex that can relax a muscle when tension becomes very high. It sits in Mondo's human body collection, one of 200 facts that each trace back to the reference below.
