Where it runs from and to

A muscle is told apart from its neighbours by what it takes hold of at each end, which is also what decides what it does when it shortens.

Origin
From the ventral surface of the tuberosity of the ischium by tendon- and muscle-fibres. The fibres diverge, and near the knee the mass has spread out, ending in a fascia.
Insertion
into rather more than the proximal one-third of the dorsal border of the tibia along its lateral margin and into the lateral margin of the patella. In passing over the knee-joint it is closely united to the underlying ligaments and tendons.
Action
Abductor of the thigh, and flexor of the shank.
Nerve
Sciatic nerve.

Written for Vetomica in its own words from the standard reference anatomy of the cat; the books it was checked against are listed below.
