| Description: Supporting cells (columnar epithelium): located in the mucous membrane lining the nose. Used for physical support, nourishment and electrical insulation for olfactory receptor cells. Basal stem cells undergo mitosis to replace olfactory receptor cells. Olfactory glands (Bowman’s glands) produce mucus that is used to dissolve odor molecules so that transduction (conversion into electrical impulses) may occur. Receptors in the nasal mucosa send impulses along branches of olfactory (I) nerve. Through the cribriform plate Synapse with the olfactory bulb Impulses travel along the olfactory tract Interpretation in the primary olfactory area in the cerebral cortex (temporal lobe) Picture Stats: Views: 3562 Filesize: 1.13MB Height: 879 Width: 1400 Source: https://biology-forums.com/index.php?action=gallery;sa=view;id=41308 |
