What is the 5th nerve?
The trigeminal nerve, also called the cranial nerve V (that’s the Roman numeral five), is the fifth of 12 cranial nerves. You have two trigeminal nerves, one on each side of your body. They start in your brain and travel throughout your head.
What nerve Innervates the jaw?
The trigeminal nerve is the largest of the 12 cranial nerves. Its main function is transmitting sensory information to the skin, sinuses, and mucous membranes in the face. The nerve communicates touch, pain, and temperature to the brain. It also stimulates movement in the jaw muscles.What does the Infraorbital nerve innervate?

Article first time published onWhat does the Abducens nerve innervate?
The abducens nerve functions to innervate the ipsilateral lateral rectus muscle and partially innervate the contralateral medial rectus muscle (at the level of the nucleus – via the medial longitudinal fasciculus).
What does the maxillary nerve innervate?
In sum, the maxillary nerve innervates the skin of the lower eyelid, the prominence of the cheek, the alar part of the nose, part of the temple, and the upper lip (Figures 2.2 and 2.3).
What does the vagus nerve innervate?
The recurrent laryngeal nerve branches from the vagus in the lower neck and upper thorax to innervate the muscles of the larynx (voice box). The vagus also gives off cardiac, esophageal, and pulmonary branches. In the abdomen the vagus innervates the greater part of the digestive tract and other abdominal viscera.
Which cranial nerves sends taste signals and what structure S does each innervate?
The three nerves associated with taste are the facial nerve (cranial nerve VII), which provides fibers to the anterior two-thirds of the tongue; the glossopharyngeal nerve (cranial nerve IX), which provides fibers to the posterior third of the tongue; and the vagus nerve (cranial nerve X), which provides fibers to the …
What is Vestibulocochlear?
The vestibulocochlear nerve (auditory vestibular nerve), known as the eighth cranial nerve, transmits sound and equilibrium (balance) information from the inner ear to the brain.
What is the Glossopharyngeal?
Introduction. The glossopharyngeal nerve is the 9th cranial nerve (CN IX). It is one of the four cranial nerves that has sensory, motor, and parasympathetic functions. It originates from the medulla oblongata and terminates in the pharynx.
What is the name of cranial nerve XII?
The hypoglossal nerve is one of 12 cranial nerves. It’s also known as the 12th cranial nerve, cranial nerve 12 or CNXII. This nerve starts at the base of your brain. It travels down your neck and branches out, ending at the base and underside of your tongue.
What does the oculomotor nerve supply?
The autonomic nervous system supplies (innervates) organs, like your eyes. The oculomotor nerve is the third cranial nerve (CN III). It allows movement of the eye muscles, constriction of the pupil, focusing the eyes and the position of the upper eyelid.
What is the function of the accessory nerve quizlet?
The accessory nerve is responsible for swallowing, head, neck and shoulder movements.
Which muscles are innervated by the trigeminal nerve quizlet?
The trigeminal nerve innervates the masseter, pterygoids, and temporalis muscles.
What is the function of Vestibulocochlear nerve?
The primary function of the vestibulocochlear nerves (VIII) is a special sensory, but of two types. The vestibular nerve handles balance and equilibrium, while the cochlear nerve is responsible for hearing. The vestibulocochlear nerves originate in the monitoring receptors of the internal ear—the vestibule and cochlea.
What is infraorbital?
Medical Definition of infraorbital : situated beneath the orbit the infraorbital prominence of the cheekbones.
What does the Nasopalatine nerve innervate?
The anterior palatine nerve innervates the gingivae and the structures of the maxillary teeth as far forward as the canines, while the nasopalatine nerve primarily innervates the mucosa surrounding the incisive papilla and the gingival margins of the maxillary incisors.
What is the infraorbital region?
The infraorbital region is a component of the midface and can be defined as the anatomical area between the nasal aperture and the zygomatic bone below the inferior rim of the orbit and above the roots of the maxillary canine and premolars (Fig. 6.1).
What does the lingual nerve supply?
The lingual nerve provides sensation to the floor of your mouth and the forward two-thirds of the tongue. The nerves that extend into your taste buds, called the chorda tympani , come from a different cranial nerve, called the facial nerve.
