On the lower surface of the tongue, this membrane is thin and smooth, but on the upper side it is covered with numerous papillae, which, in structure, are similar to the sensitivepapillae of the skin.
The circumvallate are shaped like an inverted V and are found only near the root of the tongue; the largest of this class of papillae have other very small papillae upon their surfaces.
The filiform papillae are generally long and pointed and are found over the entire surface of the tongue.
The papillae of the tongue are large and distinct, and covered with separate coats of epithelium.
Although every part of the skin is sensitive, yet the papillae are extremely so, for they are the principal means through which the impressions of objects are communicated.
It is now pretty satisfactorily established that the circumvallate, or fungiform papillae are the only ones concerned in the special sense of taste.
The papillae are irregularly distributed over the body, in some parts being smaller and more numerous than in others, as on the finger-ends, where their summits are so intimately connected as to form a tolerably smooth surface.
When the body is exposed to cold, these papillae can be more distinctly seen in the form of prominences, commonly known as "goose-pimples.
Hermann Muller also saw a small bee, an Andrena, which could not reach the nectar, repeatedly inserting its proboscis beneath the stigma, where the papillae are situated; so that these papillae must be in some way attractive to insects.

I should add that this fly apparently did not suck the nectar, but was attracted by the papillae which surround the stigma.
In the substance of the true skin are thousands of minute little bodies called papillae, which are specially concerned in the sense of touch, for the vast majority of these papillae contain the end of a small nerve.
At its very bottom, also, is thepapillae or little mound-like elevation.
The supply of blood to the skin is also very plenteous, each of its innumerable papillae being abundantly supplied in this respect.

Mouth large; lips having deep lateral folds; two complete rows of papillae on lips; five or six rows of papillae laterally.
The number of individual papillae in each tactile ridge differs considerably with age (size), so that an exact comparison between the large Amblyopsis and the much smaller species of Chologaster and Typhlichthys can not be made.
It is only in the oldest of papilliferus that the papillae become prominent.
In specimens of the same size the papillae are not more prominent in papilliferus than in cornutus.
When the epidermis is removed by maceration, the dermal papillae on which these rest give the whole head a velvety appearance.
In these cases the disease was not confined to the tonsils, but implicated the calciform papillae of the tongue also, and one of Bayer's cases some pharyngeal follicles in addition.
The head end terminates in three prominent labial papillae surrounding the mouth, and the tail end is short and conical.
The circumvallate papillae may also be enlarged, and the fungiform papillaeare sometimes very prominent and deeply congested.
The apparent obliteration of the papillae in some cases is due to a filling up of the intervening furrows by permanent deposit of new-formed cells.
The filiform papillae become elongated to several times their normal length, and feel and look like so many hairs on the tongue.
Fairlie Clarke it was found on microscopic examination that the papillaeas well as the mucous and submucous tissues were somewhat enlarged and thickened, while the bundles of muscular fibre were slightly coarser than natural.
Microscopic sections showed the large lacunae filled with corpuscles, blood-pigment in different stages of degeneration, {353} and the papillaemuch hypertrophied.
The filiform papillae are enormously elongated, so that they closely resemble hairs, and they are described by some writers as lying upon the surface of the tongue in confusion like that of a field of wheat thrown down by the wind.

When the inflammation predominates in the papillae the disease is often designated as papillary glossitis; when in the glands, it is often termed follicular glossitis.
Close examination of the parts and microscopic inspection of papillae removed for the purpose are said to show that the spores of the cryptogam are first developed at the base of the papillae, separating them from each other.

There is reason to believe that, once present, the growth of feathers was modified greatly by the degree of stimulation applied to the papillaeat roots by the movement and bending strain of the feathers.
Meisenheimer claims that he produced development ofpapillae on the thumb-pad, not only by implantation of pieces of testis, but also by implantation of pieces of ovary.
Castration during the breeding season causes the external pigmented layer with its papillae to be cast off very soon--that is to say, it has the same effect as the normal discharge of the spermatozoa.
It seems impossible that the horny layer or its papillae could atrophy in consequence of castration, or be absorbed.
Immediately after the breeding season the horny epidermis of the pad with its deeply pigmented papillae is cast off, and the thumb remains comparatively smooth from April or May until August or September.
Mere contact with the surface of the tongue, however, is not sufficient, but contact with the extremities of the nerves of taste within the papillae is required.
Although the hand is the proper organ of this sense, yet it is exercised by various parts of the body, their degree of sensibility being proportional to the number of papillae they contain.
In the third, it bristled with tiny spots similar to the papillae on a cat's tongue.
