What's the difference between mammilla and papilla?
Mammilla
Definition:
(n.) The nipple.
Example Sentences:
(1) The pattern obtained for total hexose, fucose, hexosamines, sialic acid, fructose and sulphate demonstrated that in the domestic fowl's oviduct the isthmus and the shell gland secrete the precursors for the protein carbohydrate substance of the mammillae and shell matrix and may contribute during the shell formation with the substrates necessary for the metabolic energy of the organ.
(2) A secondary operation, the "mammilla-areola complex" reconstruction and contralateral breast surgery to achieve symmetry, follow after 3-4 months.
(3) The tumors arose in the terminal ductal-lobular units as either lobular acinar carcinoma or cystadenocarcinoma or as papillary carcinomas within large ducts near the mammilla.
(4) SEM studies of thinned eggshells revealed reduced and tightly clustered mammillae with apparent decrease in intermammillary spaces and signs of inhibition of calcite formation.
Papilla
Definition:
(n.) Any minute nipplelike projection; as, the papillae of the tongue.
Example Sentences:
(1) The papillae on the oral sucker were more abundant than those elsewhere.
(2) The papilla incisiva of the Japanese children were a little larger than those of the Indians.
(3) Tissue sections, taken from foliate and circumvallate papillae, generally revealed taste buds in which all cells were immunoreactive; however, occasionally some taste buds were found to contain highly reactive individual cells adjacent to non-reactive cells.
(4) Dome-shaped, fungiform papillae were scattered among these filiform papillae.
(5) This finding supports the view that their sphincteroid action would be less efficient and that an additional closing mechanism of vascular origin may be required at the ileocaecal papilla of the horse.
(6) From the area between the papillae sensory endings appearing in sections to be either single, double or triple are described.
(7) Four of these areas were associated with central papillary atrophy; the remaining five were covered by non-atrophic mucosa with filiform and fungiform papillae.
(8) The rise in pressure approximated the sum of the rises caused by removal of the papilla alone and by renal artery constriction alone, consistent with the idea of two mechanisms being at work in this model.
(9) The receptor for atrial natriuretic peptide (ANP) in the rat renal papilla was characterized pharmacologically.
(10) After removal of the epithelium by long-term hydrochloric acid treatment at room temperature, the surface of the connective tissue papillae was observed by scanning electron microscopy.
(11) Differences between calycine units and the type I hair cell of mammals are discussed, and evidence that suggests an equilibratory function for the lacertilian papilla neglecta is presented.
(12) CR-ir was also observed in nerve fibers surrounding neuronal cell bodies in autonomic ganglia, and in nerve endings in the lip, tongue, incisal papilla, soft palate, pharynx and epiglottis.
(13) When the myoepithelial cells contract they force the axial protrusion forward and transform the papilla into a hyperboloidal configuration.
(14) Histological examination suggested that the gall sludge in the pancreatic cyst was caused by the reflux of bile into the pancreatic duct through the papilla of Vater.
(15) At late cap stage and at early bell stage receptors are not present at inner enamel epithelium level but they can be detectable in the mesenchyma of dental papilla and in some cells of the follicle.
(16) Both larval stages had an inner circle of 6 labial papillae, an outer circle of 6 labial papillae and 4 somatic papillae, and lateral amphidial pits.
(17) The Eastman Interdental Bleeding Index was a more reliable clinical indicator for detecting interdental inflammatory lesions than the Papilla Bleeding Index.
(18) Characteristics features of this species (only males were found) are the small size of body, size and type of spicules, shape of tail and arrangement of caudal papillae.
(19) With SEM the surface of the normal tongue mucosa was shown to be rather evenly covered by filiform papillae, with some fungiform papillae scattered among them.
(20) Taste buds of the mouse circumvallate papillae were studied by electron microscopy to elucidate the innervation involving the adrenergic nerve supply.
