(of Aponeurosis 1039 from, and a nerve).

The word Aponeurosis 1041 from whence comes the term nerve, used in its more extensive sense, means tendons and ligaments. Hippocrates, and other Greek writers, apply it in this way. The moderns use it to describe a very different substance. Sec Nervi. Any tendinous expansion. The tendon of a muscle, called by Hippocrates, a tendon or cord.

These expansions of tendons, called aponeuroses, or fasciae, grow thinner till they are lost in the cellular membrane. Instances of aponeuroses are frequently met with: the outward muscles of the thigh are bound down by one of these expansions, viz. the Fascia lata, q. v. Dr. Hunter describes this aponeurosis as proceeding from the musculus fasciae latae, called membranosus musculus, on the external part of the thigh, and from the gluteus maximus on the posterior part.

The fasciae of the legs, like those of the thighs, cover the muscles. The soles of the feet are strong fascia, which prevent the flexor muscles of the toes from being hurt, when we tread. The fasciae on the thighs and legs bind down the muscles while in action, and also increase their strength by compressing them.

When matter is formed immediately under any of the fasciae, it cannot point where it was first formed, but runs under them to some distance to gain an exit: to prevent inconveniences from this cause, as soon as matter can be felt under a fascia, it is right to give it vent immediately, and not to wait for its pointing, as in other situations; when this happens under the temporal muscle, great difficulties attend.
