. The cyclopædia of anatomy and physiology. Anatomy; Physiology; Zoology. A filiform papilla taken from the dorsum of a tongue in which the fur was much developed. (Mag. 30 diam.) a, imbricated scaly epithelium investing the cylin- drical portion of the papilla; b, the commence- ment of its breaking up ; c, its separation into its ultimate filamentary processes; d, the deep layer of epithelium exposed by the removal of the more scaly superficial one. * May not these varieties explain the correspond- ing diversities in the acuteness of the sense of taste, •which we so often find in different individuals? linear arrangement, principally at their con- fines, that is, in front of and around the caliciform papillae, where they are continuous with the elevations that surround these pa- pilla3, of which they are the continuations forwards and outwards, and along the whole free margin of the tongue, except at the tip, where the linear arrangement cannot be traced. In the first-mentioned situation their rows run forwards and outwards, coinciding with the arms of the V-shaped figure that the cir- cumvallate papillae assume ; in the last-men- tioned, they are placed vertically along the sides (fig. 745. i i) : they have been well de- scribed and figured by Scemmering.* Along the centre of the tongue, in the neighbourhood of the median furrow, the conical papillae often assume a cracked and fissured appearance ; but the linear arrangement is less marked here, and the fissures have no determinate direc- tion, but can be made and effaced according to the movements of the tongue. The conical papillae are largest in the neighbourhood of the circumvallate, where they are truncated, and where some of them assume almost a fungiform shape: they are longest about the centre of the tongue, near the median line, and smallest in the anterior part, near the side and tip. The form of the projections of base- ment membrane, on which the epithelium is Fig. 757.. Vertical section of conical
