A chaeta or cheta (from Ancient Greek χαίτη (khaítē) 'crest, mane, flowing hair'; pl. chaetae) is a chitinous bristle or seta found on annelid worms, although the term is also frequently used to describe similar structures in other invertebrates such as arthropods.

The meaning of CHAETA is bristle, seta.

Each chaeta is produced from an invaginated epidermal cell (chaetoblast). The outer cell membrane of each chaetoblast is covered with microvilli, each of which produces a slender cylinder of chitin. These cylinders are glued together …

A chaeta or cheta (from Ancient Greek χαίτη (khaítē) 'crest, mane, flowing hair'; pl. chaetae) is a chitinous bristle or seta found on annelid worms, although the term is also frequently used to describe similar structures in other invertebrates such as arthropods.

The chaeta may be tapering capillaries, but most chaetae are much more complex (Figure 5). A species may have a single kind of chaetae or two or more kinds; in some parapodia each chaeta may be different, but more usually groups of chaetae with similar structure are present.

A chaeta is a bristle or hair-like structure on the body of many types of invertebrates, especially annelids such as earthworms. They are typically composed of chitin and serve various functions such as locomotion, sensory perception, or defense.

Mar 3, 2015 · Like annelids, echiurans possess chaetae, a single ventral pair in all species and one or two additional caudal hemi-circles of chaetae in two subgroups, but their evolutionary origin and affiliation to annelid chaetae are unresolved.

Meaning of chaeta medical term. What does chaeta mean?
