Nasal epithelia, alligator (labels) - TEM

This is a histology slide from an American alligator. Solitary chemosensory cell (SCC) in the olfactory epithelium. The cytoplasm is filled with small vesicles. The surrounding supporting cells (sc) constrict the apical ending of the SCC into a "neck" (small arrows).

Large arrow - OSN (olfactory receptor neuron).
