Which cranial nerves have sensory afferents?
Cranial nerves I, II, and VIII (olfactory, optic, and vestibulocochlear nerves) go to the sensory organs and they have afferent fibers.
Where is the chorda tympani located?
Structure and Location The chorda tympani branches off from the facial nerve in its vertical segment of the temporal bone (the main skull bone that houses the inner ear). It passes behind the ear drum and between two tiny bones of the middle ear called the incus and malleus.
What are the 3 sensory cranial nerves?
Cranial nerves I, II, and VIII are pure sensory nerves. Cranial nerves III, IV, VI, XI, and XII are pure motor nerves. Cranial nerves V, VII, IX, and X are mixed sensory and motor nerves.
Is glossopharyngeal neuralgia life threatening?

What happens if the chorda tympani is damaged?
The chorda tympani (CT) nerve innervates lingual taste buds and is susceptible to damage during dental and inner ear procedures. Interruption of the CT results in a disappearance of taste buds, which can be accompanied by taste disturbances.
What does the chorda tympani innervate?
The chorda tympani nerve is a branch of the facial nerve that innervates taste to the anterior two thirds of the tongue.
Which cranial nerve controls motions of the neck muscles?
Your accessory nerve is a motor nerve that controls the muscles in your neck. These muscles allow you to rotate, flex, and extend your neck and shoulders.
What nerve does chorda tympani join?
the lingual nerve
Chorda tympani nerve It merges with the lingual nerve, a branch of the maxillary nerve (V3). This nerve transports the nerves of taste for the anterior two-thirds of the tongue and contains secretory fibers for the sublingual and submaxillary glands.
Which type of fibers are carried in chorda tympani nerve?
Function. The chorda tympani carries two types of nerve fibers from their origin with the facial nerve to the lingual nerve that carries them to their destinations: Special sensory fibers providing taste sensation from the anterior two-thirds of the tongue.
