Olfactory and solitary chemosensory cells: two different chemosensory systems in the nasal cavity of the American alligator, Alligator mississippiensis
Abstract Background The nasal wd6001fsyz cavity of all vertebrates houses multiple chemosensors, either innervated by the Ist (olfactory) or the Vth (trigeminal) cranial nerve.Various types of receptor cells are present, either segregated in different compartments (e.g.in rodents) or mingled in one epithelium (e.g.fish).In addition, solitary chemos
