    muscles of the thigh ; e, the great sciatic nerve; d, the small sciatic nerve ; a, a, a, the posterior branches of the sacral nerves, seen emerging from the vertebra of the spine ; b, the gluteal nerve ; o, o, the internal pudic nerve. The great sciatic nerve is the largest nerve in the body ; from its size and direction, it may be considered as the continuation or prolongation of the spinal plexus, it being impossible to determine -where the one ceases or the other begins. The fasciculi, -which enter into its composition or bundle, are derived from all the nerves which go to form the sacral plexus, and every voluntary motion of the leg and foot has to be transmitted through some of the nerves of this bundle. The great sciatic nerves divide generally about the middle of the thigh into an external and internal branch, the latter proceeding down to the heel, as shown in Eng. 2 ; from this will be seen the natvu-e of sciatica. Exg. II.—a, a, shows the continuation of sciatic nerve, called here the pop- liteal nerve, b, the fibular nerve ; 10, 12, 13, muscles. The tendon Achilles divided,, 19, the tendon of the flexor muscle; 20, the tendon Achilles ; 18, the posterior tibial artery. Exgravixg I. (Quain and Wilson.) Magnified view of muscular fibres in the state of repose. The main nerve is seen pro- ceeding down the centre, with branches from it on each side. This snows the state of the muscles and nerves when a liinb is at rest; when the limb or any part is moved, the elec- trical shock from the nervous centres, by the action of the mind, is shown at Engraving IT]. the xei'.vks, OB TBL26SATB WEBBS, ix Tin: Mrscr.r.s on n.Esn.
