The papilla foliata of the Rabbit’s tongue was removed together with a small amount of the surrounding epit helium and underlying tissue extending about 2 mm deep. In case of the olfactory epithelium, the olfactory mucous membrane lining the posterior portion of the basal septum of the nose was taken. Both tissues were fixed in chilled 10% neutral formol saline for 5 mins. prior to sectioning. This short fixation improved the morphological picture. Fifty-micron fresh frozen sections were cut… 
Cholinesterases in the tongue of the potto (Perodicticus Potto)
TLDR
The tongue has three circumvallate papillae, arranged in a triangle ahead of the foramen caecum, and the ventral aspect of the tongue has fewer nerve fibers and end organs than the dorsal surface does.
On the cholinesterase activity of encapsulated nerve endings in the tongue of the cat
TLDR
It has been shown, that the submucosal areas, stained by the first method really represent components of these receptors, and that the high cholinesterase activity of the inner bulb is not peculiar for these receptors alone.
Cholinesterase activities in the gustatory region of the rat tongue and their inhibition by bitter-tasting substances.
TLDR
The cholinesterase activity in the taste bud areas was found to be in-hibited by several kinds of bitter-tasting substances, including quinine hydro-chloride, methantheline bromide, berberine hydro chloride, L-methylephedrine hydrochlorides, phenobarbital sodium and sodium dehydrocholate.

TLDR
The apical region of the taste bud is divided into a distal taste pore, a channel, and a proximal chamber that contains an amorphous dense material histochemically defined as a neutral mucopolysaccharide, which finally reaches the chamber.

Alkaline phophatase, adenosine triphosphatase and acid phosphatase activity was demonstrated in the tongues of the rat and rabbit, especially in relationship to taste buds.1. Alkaline phosphatase was
Ganglion Cells and Topographically Related Nerves in the Vallate Papilla/von Ebner Gland Complex
TLDR
The presence of different neuronal subclasses suggests that a certain degree of functional specialization may exist in the VP/VEG complex peptidergic, cholinergic, and nitrergic neurons.
Fine Structural Localization of Acetylcholinesterase in the Olfactory Mucosa in Guinea Pig and Rabbit
Using histochemical procedures for electron microscopy, acetylcholinesterase (AChE) activity was demonstrated in the olfactory mucosa of the guinea pig and rabbit. This activity was found in two

TLDR
The mucus layer of the olfactory epithelium of mammals is produced by the Bowman glands, while in chondrichthians it is formed by the Becher cells and probably by other mucosa cells also.
Histological and histochemical studies on the rhesus monkey (Macaca mulatta) olfactory mucosa
TLDR
The degenerating receptor cells as well as the olfactory nerve fasciculi which are not completely covered by the flat squamous cells may make the locus minoris resistentiae in the ofactory mucosa, which seems to be metabolically very active and both cholinergic and adrenergic in nature.
