We’re continuing along on our discussions of hip flexors, and thus we can’t not talk about Sartorius.
Sartorius is a weird muscle. First off, it’s the longest muscle of the human body.
And, in addition to crossing the hip joint, it also crosses the knee joint, but it doesn’t extend the knee like its cousins the quadriceps group.
Sartorius actually flexes the knee joint!
I say that sartorius is weird because we’ve been talking about the muscles on the front of the quad and if you think about the movement of the knee (that flexion and extension), you’d think that a muscle on the front of the body would only be able to extend the knee based on it’s position.
BUT NOOOOOO, enter swoopy sartorius to shake things up.
