myocoeln.

Brit.

/ˈmʌɪə(ʊ)siːl/, U.S.

/ˈmaɪoʊˌsil/

Forms: 1800s– myocoel, 1900s– myocele, 1900s– myocoele.

Origin: Formed within English, by compounding; modelled on a German lexical item. Etymons: myo- comb. form, -coele comb. form.

Etymology: < myo- comb. form + -coele comb. form, after German Myocöl (B. Hatschek 1888, in Anatomischer Anzeiger 15 Aug. 662). Compare myocoelomic adj.The form myocele is probably by confusion with -cele comb. form.

Embryology and Zoology.

In vertebrate embryos: a cavity in the centre of an early myotome. Also: a compartment of the coelom associated with each myotome in adult amphioxus ( Branchiostoma) and other cephalochordates.
