It is insertedinto the tendo calcanea, not far from the heel. 2o6 MYOLOGY Actions.—Extends the foot. Nerve Supply.—Tibial nerve by two branches; that to the super-ficial surface is from the first and second sacral nerves; that for thedeep surface is from the fifth lumbar and first and second sacralnerves.
