Seta \Se"ta\, n.; pl. Set[ae]. [L. seta, saeta, a bristle.] 1. (Biol.) Any slender, more or less rigid, bristlelike organ or part; as the hairs of a caterpillar, the slender spines of a crustacean, the hairlike processes of a protozoan, the bristles or stiff hairs on the leaves of some plants, or the pedicel of the capsule of a moss. 2. (Zo["o]l.) (a) One of the movable chitinous spines or hooks of an annelid. They usually arise in clusters from muscular capsules, and are used in locomotion and for defense. They are very diverse in form. (b) One of the spinelike feathers at the base of the bill of certain birds.
Setae prevent worms (Annelids) to backslide during locomotion, effectively serving as "anchors".
They are stiff bristles (hair_like) on the earthworm. Its function, to help grip on surface and aid with moving without going backwards. Found in grooming limbs and some mouth parts.
The Setae, located on the underside of the worm.
Penial setae refer to the sperm ducts of invertebrate animals. Penial setae are bristle-like structures on segmented invertebrates such s worms. They are usually located behind the worms' prostates.
setae means setae wich is a sofa
What segment of the worm contains no no Setae ?
Plant bristles are called setae or awns. The setae are movable bristles. Setae are also known as being a stiff hair.
Bristles also known as setae. They work as legs; they grip to soil with the setae. Setae also can dig through soil.
Setae are little bristles attached to segments of annelids. It helps them move.
Well the setae is what allows earthworms to move thorugh the dirt and stuff :)
The setae are small spines which are projected from the body wall by muscles to act as anchors in the surface that the worm is moving along. The muscle can also retract the setae The circular muscles contract and expand in co-ordination with the longitudinal muscle in series such as that if the posterior muscle are expanded and the anterior circular muscles are contracted the worm pushes and stretches its front end forward. The anterior muscles then expand to anchor its front end by use of the setae and the rear end is pulled forward. All this happens in a smooth and rhythmic motion.
They are setae. They help the worm move, like little legs.
The small bristles on earthworms are called setae. The setae are small spines which are projected from the body wall by muscles to act as anchors in the surface that the worm is moving along. The muscle can also retract the setae when it is not required.
