ALA

Written by

A winged-like expansion of cuticular integument of nematodes; an expansion at the oesophageal region called “cervical alae”, e.g. in Toxocara species, or at the posterior end called “caudal alae” and in the larval stages of some nematodes the expansion may extend almost entire lateral aspects of the body, these expansions are called “lateral alae”. In Oxyuridae, e.g. Enterobius vermicularis, the cuticle at the anterior end expands dorso-ventrally into “cephalic alae”.
