Encyclopedia > Buccal nerve

A branch of the mandibular nerve (which is itself a branch of the trigeminal nerve), the buccal nerve transmits sensory information from skin over the buccal membrane (in general, the cheek) and from the second and third molar teeth. It courses between the two heads of the lateral pterygoid muscle, underneath the tendon of the temporalis muscle, and then over the masseter muscle to connect with the buccal branches of the facial nerve. Small nerves that branch off of the buccal nerve innervate the lateral pterygoid muscle. The mandibular nerve is the third branch (V3) of the trigeminal nerve. ... The trigeminal nerve is the fifth (V) cranial nerve, and carries sensory information from most of the face, as well as motor supply to the muscles of mastication (the muscles enabling chewing), tensor tympani (in the middle ear) and other muscles in the floor of the mouth, such as the...

Buccal nerve - Wikipedia, the free encyclopedia (379 words)
A branch of the mandibular nerve (which is itself a branch of the trigeminal nerve), the buccal nerve transmits sensory information from skin over the buccal membrane (in general, the cheek) and from the second and third molar teeth.
The Buccinator Nerve (long buccal nerve) passes forward between the two heads of the Pterygoideus externus, and downward beneath or through the lower part of the Temporalis; it emerges from under the anterior border of the Masseter, ramifies on the surface of the Buccinator, and unites with the buccal branches of the facial nerve.

Olfactory nerve - Wikipedia, the free encyclopedia (419 words)
The specialized olfactory receptor neurons of the olfactory nerve are located in the olfactory mucosa of the upper parts of the nasal cavity.
The olfactory nerve consists of a collection of sensory nerve fibers that extend from the olfactory epithelium to the olfactory bulb, passing through the many openings of the cribriform plate, a sieve-like structure.
The olfactory nerve is the shortest of all the twelve cranial nerves and only one of two cranial nerves (the other being the optic nerve) that do not join with the brainstem.
