Olfactory system, the bodily structures that serve the sense of smell. The system consists of
the nose
and the nasal cavities, which in their upper parts support the olfactory mucous membrane for the perception of smell and in their lower parts act as respiratory passages.
What structures are involved with smelling scents?
The olfactory receptor neurons are incorporated into a limited region of the nasal epithelium in the superior nasal cavity. Anatomy of the Structures Involved in Smell (Olfaction). The
olfactory bulb
(1) contains mitral cells (2) that receive information from the olfactory cells (6).
Which sensory structure is sensitive to odors and smells?
In humans and other vertebrates, smells are sensed by olfactory sensory neurons in
the olfactory epithelium
What do you call the tissue that is sensitive for smell?
Up on the roof of the nasal cavity (the space behind your nose) is
the olfactory epithelium
(say: ol-FAK-tuh-ree eh-puh-THEE-lee-um). Olfactory is a fancy word that has to do with smelling. The olfactory epithelium contains special receptors that are sensitive to odor molecules that travel through the air.

the back of nose
, where millions of sensory neurons lie in a strip of tissue called the olfactory epithelium. The tips of these cells contain proteins called receptors that bind odor molecules.
What smell are humans most sensitive to?
Scents that humans are particularly attuned to include chemical components in

What do you smell with?
Whenever we smell something, our nose and brain work together to make sense of hundreds of very tiny invisible particles, known as molecules or chemicals, that are floating in the air. If we sniff, more of these molecules can reach the roof of our nostrils and it is easier to smell a smell.
What does it mean when you keep smelling something burning?
