1.Receptors in the muscular tissue of 4 Hegu and 3 Yungquan points were studied by the methods of Bielschowsky and Faworsky.The following four kinds of receptors were revealed:(1)Free nerve endings attached onto the surface of muscle fibers and ending within the con-nective tissue between muscle fibers.(2)Muscle spindles(3)Plexiform receptors within the fascia propria(4)Perimuscle fiber plexiform receptor.2.In one muscle spindle

on the nuclear bag region of a nuclear bag fiber

a special kind of nerveending which is unlike the typical primary spiral one was discovered and described.3.A new kind of muscle receptor

which had never been described

was discovered in the musculartissue of one Hegu point.It is Peariform and the diameter of it is about 400 micra.A small bundleof thick nerve fibers

penetrating into the connective tissue of a bundle of muscle fibers

divided re-peatedly to form a very complex plexus

part of which surrounded each muscle fiber and the othersended within the connective tissue with rminal expansions.
