Etymology

Semimembranosus comes from the parts semi- and membrane, where semi- means 'half' and membrane means 'thin skin' or 'cover'. A helpful way to remember it is to think of a 'half-membrane' muscle, because one of the hamstrings has a flat, thin part, so the name points to its shape and its place at the back of the thigh.
