A&P olfaction

Where is the olfactory epithelium located

Roof o f the nasal cavity

What are the receptor cells for odorants

Olfactory sensory neurons, bowling-pin shaped receptor cells in the superior nasal concha

What is the structure of olfactory sensory neurons

Bipolar neurons; thin apical dendrite that terminates in a knob from which several long cilia radiate

Olfactory cilia increase receptive surface area and typically lie flat on the nasal epithelium, covered by a coat of thin mucus that acts as a solvent

Where do axons of the olfactory sensory neurons go

Thin, unmyelinated axons of the olfactory sensory neurons form fascicles that together form filaments of the olfactory nerve (CN I) that go through the ethmoid bone to the olfactory bulbs in the frontal lobe

What cells make up the bulk of the epithelial membrane

Supporting cells that surround and cushion olfactory sensory neurons

What happens physiologically after dissolved odorants reach the nose
