Alary muscles

Definition

Thin, ribbon-like muscles that attach to the walls of the insect heart (dorsal vessel) and help facilitate the circulation of hemolymph within the body.

Etymology

From Latin 'alaris', meaning 'pertaining to wings', though in this context, it refers to the shape and positioning of the muscles rather than to wings.

Example

The alary muscles in the mosquito help pump hemolymph through its dorsal vessel, ensuring proper circulation throughout its body.

Synonyms
