Olfactory tract Olfactory bulb Nasal conchae Route of inhaled air Olfactory epithelium Olfactory nerve fibers

Mitral cell (output cell) Olfactory gland Olfactory tract Olfactory epithelium Filaments of olfactory nerve Cribriform plate of ethmoid bone Lamina propria connective tissue Basal cell Supporting cell Dendrite Olfactory cilia Olfactory bulb Glomeruli Axon Olfactory receptor cell Mucus Route of inhaled air containing odor molecules

Special Sensory Reception Gustation

Fungiform papillae Foliate papillae Umami

Taste bud Circumvallate papilla

Taste fibers of cranial nerve Gustatory (taste) cells Taste pore Gustatory Hair (microvilli) Stratified squamous epithelium of tongue Basal cells
