What is the function of the glossopharyngeal nerve?
The glossopharyngeal nerve is responsible for providing sensory information from the back of the throat, taste sensation from the back of the tongue, and motor function to some of the muscles involved in swallowing. It also plays a role in regulating blood pressure and monitoring oxygen levels in the blood.
The nerve that contains the sensory fibers are involved in hearing?
The vestibulocochlear nerve (CN VIII) contains the sensory fibers involved in hearing. It carries auditory information from the cochlea of the inner ear to the brain for processing. Damage to this nerve can result in hearing loss or other auditory issues.
What type of nerve fibers are found in the ventral ramus of a spinal nerve?
The ventral ramus of a spinal nerve contains both sensory and motor nerve fibers. These fibers innervate the muscles, joints, and skin on the front part of the body.
What nerve carries only sensory fibers?
nerves carrying just sensory fibers are referred to as sensory and or what nerves?
The dorsal root of a spinal nerve contain what?
axons of sensory neurons
Is the glossopharyngeal nerve the only nerve that contains sensory fibers?
no
Mixed cranial nerves containing both motor and sensory fibers include trigeminal?
The trigeminal nerve (cranial nerve V) is a mixed cranial nerve that contains both sensory and motor fibers. It is responsible for sensation in the face and motor functions such as biting and chewing. The sensory component detects touch, pain, and temperature from the face, while the motor component innervates the muscles of mastication. Other mixed cranial nerves include the facial nerve (VII), glossopharyngeal nerve (IX), and vagus nerve (X).
What is the function of the glossopharyngeal?
It contains both sensory and motor fibers, and supplys the tongue soft palate, pharynx, and parotid gland.
What other cranial nerves contain sensory fibers?
The listed cranial nerves provide both sensory and motor innervation:Trigeminal nerve (CN V)Facial nerve (CN VII)Glossopharyngeal nerve (CN IX)Vagus nerve (CN X)
Two cranial nerves involved in taste are?
facial nerve`s branch - Chorda tympani provides parasympathetic innervation to submandibular gland and sublingual gland and special sensory taste fibers for the anterior 2/3 of the tongue glossopharyngeal nerve whitch receives special sensory fibers (taste) from the posterior one-third of the tongue
What do the mixed cranial nerves containing both motor and sensory fibers include?
Olfactory
What is the function of the glossopharyngeal nerve?

It also plays a role in regulating blood pressure and monitoring oxygen levels in the blood.
The nerve that contains the sensory fibers are involved in hearing?
The vestibulocochlear nerve (CN VIII) contains the sensory fibers involved in hearing. It carries auditory information from the cochlea of the inner ear to the brain for processing. Damage to this nerve can result in hearing loss or other auditory issues.
Where are the majority of parasympathetic fibers found?
The majority of parasympathetic fibers are found in the cranial nerves (specifically the oculomotor, facial, glossopharyngeal, and vagus nerves) and in the sacral spinal cord (S2-S4). These fibers innervate various organs such as the heart, lungs, and digestive system, promoting rest and digestion.
What cranial nerves are involved in tooth ache in upper jaw?
The cranial nerve would be the 5th one (V), the Trigeminal. This nerve is responsible for conduction sensory impulses from the skin of the face and mucosa of the nose and mouth. Also, it contains motor fibers that activate the chewing muscles.
What is pharyngeal chaisma?
The pharyngeal chiasm is a structure located at the level of the pharynx where fibers of the glossopharyngeal nerve (cranial nerve IX) and the vagus nerve (cranial nerve X) intersect. It plays a role in innervating muscles involved in swallowing and regulating various functions of the pharynx and larynx.
What nerve that contains fibers that both send and receive messages is called?
A mixed nerve, such as the trigeminal nerve, contains both sensory and motor fibers that can send and receive messages. These nerves are responsible for carrying both sensory information from the body to the brain and motor commands from the brain to the muscles.
