Each possesses a stalk, to which it is attached, and which consists of a single medullated nerve fibre (Fig. 108), differing froin an ordinary medullated nerve fibre merely in the fact that outside its neuri- lemma there is present a thick laminated connec- tive-tissue sheath. This is the sheath of Henle —continuous with the perineural sheath of the nerve branch with which the nerve fibre is in con- nection. This medullated nerve tibre within its sheath possesses generally a very wavy outline. The corpuscle itself is com- posed of a large number of lamella, or capsules, more or less concentric- ally arranged around a central elongated or cylin- drical clear space. This space contains in its axis, from the proximal end— the one nearest to the stalk—to near the opposite or distal end, a continuation of the nerve tibre in the shape of a simple axis cylinder. But this axis cylinder does not fill out the central space, since there is all round it a space left filled with a transparent substance, in which, in some instances, rows of spherical nuclei may be perceived along the margin of the axis cylinder. At or near the distal end of the central space the axis cylinder divides in tico or Fig. lOS.—Pacinian Corpuscle, from the Mesentery of Cat. a, Medullated nerve fibre: b. concen- tric capsules.
