nerve of olfaction is ?

nerves of olfaction = 1,7,9,5,10 OLFACTORY SYSTEM * Olfactory epithelium- receptor cells, suppoing cells and basal cells Receptor cells are bipolar neurons, distal process carries cilia that project into nasal cavity. Cilia have receptors for odoriferous molecules. Axons from the olfactory sensory neurons converge in the cy.. bulb to form clusters called glomeruli. These nerve fibers,are lacking in myelin sheaths. The glomerulus is a spherical structure located in the olfactory bulb of the brain where synapses form between the terminals of the tufted cell.and the dendrites of mitral, periglomerular and ref : guyton and hall
