Calyx (anatomy)
Calyx is a term used in animal anatomy for some cuplike areas or structures.
Etymology
Latin, from calyx (from Ancient Greek κάλυξ, case of a bud, husk").
Cnidarians
The
soft corals
(also called calice).
Entoprocta
A body part of the Entoprocta from which tentacles arise and the mouth and anus are located.[1]
Echinoderms
The body disk that is covered with a leathery tegumen containing calcareous plates (in
viscera are located).[2]
Humans
Either a
major calyx, or the Calyx of Held, a particularly large synapse in the mammalian auditory central nervous system, named by H. Held in his 1893 article Die centrale Gehörleitung,[3] due to its flower-petal-like shape.[4]
Insects
In male insects, a funnel-shaped expansion of the basal part of the insect brain (a component of the corpus pedunculatum) and by certain female insects, an expansion of the oviduct into which the ovarioles open.
