What's the difference between cnidocil and filiform?
Cnidocil
Definition:
(n.) The fine filiform process of a cnidoblast.
Example Sentences:
(1) The external surface of the hypostome possesses cnidocils, possibly sensory hairs, and small spiny protrusions surrounding the mouth; the internal surface has cylindrical microvilli, free flagella and adherent flagella.
(2) Spindles and stem cell microtubules disappeared at 0.8-1 nM-nocodazole, followed by nerve microtubules (about 2 nM), cnidocil microtubules (10 nM) and finally by nematocyte microtubules (34 nM).
(3) The origin of nematocysts as kinetosomal derivatives is discussed as a possibility suggested by the symmetry of the stenotele contents and the structure, location, and function of the cnidocil.
(4) A network of fibers and microtubules, originating in the cnidocil, extends to the base of the nematocyte stalk.
Filiform
Definition:
(a.) Having the shape of a thread or filament; as, the filiform papillae of the tongue; a filiform style or peduncle. See Illust. of AntennAe.
Example Sentences:
(1) Dome-shaped, fungiform papillae were scattered among these filiform papillae.
(2) Four of these areas were associated with central papillary atrophy; the remaining five were covered by non-atrophic mucosa with filiform and fungiform papillae.
(3) 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.
(4) The filiform papillae were also examined by light and transmission electron microscopy.
(5) That of the small conical filiform papillae is to take food efficiently into the oral cavity.
(6) Fungiform papillae which had a round depression on the top were distributed sporadically among the filiform papillae, and contained columnar CTC with several plane striations running longitudinally along the lateral surface.
(7) The vascular anatomy of the filiform and fungiform papillae of the feline tongue was studied by i.a.
(8) Brain astrocytes have filiform profiles and most appear to be deployed as radial glia.
(9) However, in the cases of the 6-W and 9-W wounds the regenerated papillae filiformes were morphologically different from the original ones.
(10) Fungiform papillae are scattered among these filiform papillae, and are numerous at the anterior margin of the tongue.
(11) Neuritic growth cones of the filiforme, or lamellipodiale type were demonstrated as well as button-like dendritic growth cones.
(12) A circular zone devoid of identifiable connective tissue is present at the center of the filiform excrescences.
(13) The stenoses were mostly of filiform type, the diameter being 1-3 mm (79%) less frequently 4-7 mm (21%).
(14) The instantaneous spike frequency of PAD unit discharges matches the evoked depolarization very closely, and during such depolarizations spike amplitudes in the filiform afferent terminals are reduced by up to 55%.
(15) The group of patients under 60 years also presented with significantly lower flow velocity values of the homolateral A. cerebri media, but only in the cases with filiform stenoses or occlusions.
(16) Histologically, the polyps were filiform, with a central core, containing vessels and smooth muscle fibers.
(17) Three out of seven filiform warts were positive for HPV2, three were positive for both probes, and one was negative for both.
(18) The distribution pattern of filiform papillae was similar both in the musk shrews and mongoose, in that the form of filiform papillae changed gradually from the lingual apex to the posterior part of the lingual body.
(19) The delicate filiform tip also contributes to greater safety.
(20) The filiform papillae are composed of four layers; outer, upper intermediate, lower intermediate, and basal layer.
