Recepteurs de tension de la region de la bouche chez Blaberus craniifer burmeister (Dictyoptera: Blaberidae)

摘要: Four stretch receptors are associated with the wall of preoral cavity (cibarium) Blaberus: I in epipharynx and 3 hypopharynx. These sensory cells transverse connective tissue strands. The strands attached at each extremity to integument by a conjunctive-epidermo-cuticular junction identical myo-epidermo-cuticular muscle attachments. Each strand receives dendrites multiterminal (type 11) which never—even when they bipolar—possess any ciliary structure. glial lacunar system, is extensively developed around axons, disappears dendrites. distal parts very rich mitochodria. “naked” where transduction mechanism probably situated. The unique their histological complexity: same can receive 14 different morphological properties. Some these regularly packed small anatomical units not ganglia. complex able insure some peripheral analysis mechanical events feeding. Associated receptor efferent fibres. contain dense core vesicles it suggested that Support central control “neurosecretomoteur” mechanism.
