A cuticular process that is clearly articulated with the basal cuticle. This structure comes in many forms. There is a tendency in the literature for some authors to call heavily sclerotized setae "spines", even though they have smaller counterparts of the same form named "setae" by the same authors. "Spinose seta" or "spine-like seta" is more accurate.
Slender, hairlike or bristly projections arising from the epidermal layer on any part of the body of an insect.[1] Fin. Swe.
Hair-like sensory structure that is articulated basally; sometimes called a trichoid sensillum (see also longitudinal sensillum). [photo
The stalk on which the capsule is borne.
hairs or whiskers in the spore-bearing structures of certain fungi
A stiff hair-like structure, made of chitin, often found on fleshy appendages. Synapomorphy of the Annelida.
Very large, dark hairs that are often arranged in specific patterns.
A cuticular process that is clearly articulated with the basal cuticle. This structure comes in many forms. Some papers in the isopod literature may use the term “spines” when heavily sclerotized setae are indicated. "Robust seta" or "spine-like seta" for such heavy setae is more accurate.
a bristle; often with branches
a slender, flexible, chitinous outgrowth of the body or limb surface
(I,II) [horn, awn, bristle, spine] Figs 5F, H, J, K, 59-66 A hollow outgrowth of the valve projecting outside the valve margin, with a structure different from that of the valve. Although much of the fine structure of setae, such as the pattern of perforation, can be observed only with the aid of electron microscopy, many features can be seen with the light microscope, and they provide valuable information for species delineation. In cross section, setae may be round, square or polygonal (Evensen & Hasle 1975). In some species, such as C. lorenzianus, rows of pores on the setae can be seen in the light microscope. Setae often have a row or rows of small spines which spiral around the seta for some or all of its length. In some cases the setae themselves are spirally twisted, and the spirals of spines visually accentuate this. Chaetoceros radicans setae bear capilli which are perpendicular to the setae, and distally decrease in frequency.
Hair-like process of cuticle that is clearly articulated with the basal cuticle (see spine). Some authors call very solid, thickened setae "spines," but "spinose setae" or "spine-like setae" is more accurate. Robust setae are very stout setae, as opposed to slender setae. Plumose setae have small setules, giving a feather-like appearance (Wilson, 1989). Pectinate setae have small spines, giving a comb-like appearance.
A hardened, hairlike projection surrounded at the base by a small ring.
A socketed hair which has a single trichogen cell at the base. The socket itself is formed by the closely associated tormogen cell. See also spine and spur.
hairlike outgrowth from head or body.
(pl. setae) 1. the erect aerial part of the spore-producing structure of mosses or liverworts. 2. a slender, straight prickle.
(pl. Setae): The hairlike structure commonly found on caterpillars and other insects.
Slender hairlike appendage.
A slender, hair-like, usually sensory extension of the cuticle, connected to the body wall by a socket.
(pl. setae), a hairlike structure
a stiff hair or bristle. pl. setae.
Hairs or bristles that are hollow structures developed as extensions of the insect epidermis.
a bristle or stiff hair; terminal seta: an appendage to the tip of an organ, e.g. to the primary rachis of a bipinnate leaf in Acacia. adj. setaceous.
( See-ta; plural: setae [ see-tee]): stout hair that is set in a socket in the cuticle.
1. A bristle. 2. In mosses, the stalk holding the spore capsule.
Hair-like bristles mostly used for locomotion.
sensory structures of insects that resemble small hairs, or hairlike structures of fungi such as Glomerella.
Slender, hairlike, or bristly projection arising from the surface of a plant or the epidermal layer on any part of the body of an insect.
1. In nematodes: Elongated cuticular structures articulating with the cuticle; in general, tactile sensory organs usually located around the oral openings. ( 14) 2. In fungi: A bristle-like structure in some types of fruiting bodies. ( 16) (Pl. setae.)
A bristle or bristle-like structure.
A seta is a stiff hair, bristle, or bristle-like process or part of an organism. The plural form is setae.
