- So what's the point of going back to the thalamus if we're just going to go to another area?
- Indeed! Lets head on over to smell!
- Nostril
- Nasil Vestibule
- Hard Palate
- Nasil Conchae
- Olfactory Bulb
- Nerve Bundles
- Pharyngeal Tonsil
- NOSTRIL: Two external openings that lead to the nasal cavity. NASIL CONCHAE: Provides rapid warming and humidification of the air. NASIL VESTIBULE: The most anterior part of the nose. It is enclosed by the cartilage of the nose and lined by the epithelium on the skin. OLFACTORY BULB: Spheres of nerve tissue called glomeruli. They are formed from the branching ends of axons of receptor cells and from the outer branches of interneurons.
- Of course, whatever we smell just goes into our nostrils which is then absorbed by the olfactory bulb. Through the use of sensory neurons, nerve impulses are sent once again to the thalamus! From there, it is sent back to the nose, thus creating smell!

- Now the good ol' taste buddies!
- GLOSSOPHARYNGEAL NERVE: A mixed nerve that carries afferent sensory and efferent motor information. It exits the brainstem out from the sides of the upper medulla, just rostral (closer to the nose) to the vagus nerve. VAGUS NERVE: One of the cranial nerves that connect the brain to the body. The vagus nerve has two bunches of sensory nerve cell bodies, and it connects the brainstem to the body. It allows the brain to monitor and receive information about several of the body's different functions. SUPERIOR LARYNGEAL NERVE: A branch of the vagus nerve. It arises from the middle of the inferior ganglion of vagus nerve and in its course receives a branch from the superior cervical ganglion of the sympathetic nervous system. CHORDA TYMPANI NERVE: A branch of the facial nerve that originates from the taste buds in the front of the tongue, runs through the middle ear, and carries taste messages to the brain.
