The stichosome (posterior glandular esophagus) of Capillaria pterophylli Heinze, 1933 consists of large gland cells (stichocytes) and lumenal epithelium with cuticular lining. Both structures are enclosed in a reticulum of muscle cells. The stichocyte cytoplasm contains small cisternae of rough endoplasmic reticulum, Golgi complexes, one kind of electron dense secretory granules, mitochondria and a branching system of intracellular collecting ducts without filament bundles around them.
Résumé
Le stichosome (partie postérieure glandulaire de l'œsophage) de Capillaria pterophylli Heinze, 1933 est formé de grandes cellules glandulaires (stichocytes) et d'un épithélium revêtu de cuticule entourant la lumière œsophagienne. Ces deux structures sont enfermées dans un réseau de cellules musculaires. Le cytoplasme du stichocyte contient des petites citernes de reticulum endoplasmique rugueux, des complexes de Golgi, un seul type de granules de sécrétion denses aux électrons, des mitochondries et un système ramifié de canaux collecteurs intracellulaires qui ne sont pas entourés de faisceaux de filaments.
