Which of the following cranial nerves carries only motor information?

The trochlear, abducens, accessory, and hypoglossal nerves are only motor nerves; the trigeminal nerve is both sensory and motor; the oculomotor nerve is both motor and parasympathetic; the facial glossopharyngeal, and vagus nerves have sensory, motor, and parasympathetic components (Standring, 2008).

Which cranial nerve transmits information about audition?

The vestibulocochlear nerve (CN VIII) transmits information regarding two very important senses: audition and balance. Auditory information is transmitted by the cochlear part of the vestibulocochlear nerve, and information on balance is transmitted by the vestibular part of the vestibulocochlear nerve.

What is the main function of CN I?

CNs have sensory (afferent) and motor (efferent) functions. CN I and CN II convey sensory information. … All the other CNs originate from the brainstem nuclei (the hypoglossal nerve is located at the border of the spinal cord) and include sensory axons as well as motor axons.

Which cranial nerve transmits information about audition quizlet?

Which cranial nerve transmits information about audition? The vestibular branch of the vestibulocochlear nerve transmits afferent impulses for the sense of equilibrium.

Which cranial nerve Innervates most of the visceral in the thoracic?

Vagus nerve
The correct answer is (E): Vagus nerve (X). Among the cranial nerves, the vagus nerve is the only one that innervates the structures outside of the…

Which cranial nerve transmits auditory information Vestibulocochlear abducens optic vagus?

The vestibulocochlear nerve, also known as cranial nerve eight (CN VIII), consists of the vestibular and cochlear nerves.

Which of the following cranial nerves carries only sensory information quizlet?

The glossopharyngeal nerve is the only cranial nerve that contains sensory fibers.

Which nerve does not arise from the brachial plexus?

Function. The brachial plexus provides nerve supply to the skin and muscles of the arms, with two exceptions: the trapezius muscle (supplied by the spinal accessory nerve) and an area of skin near the axilla (supplied by the intercostobrachial nerve).

Which of the following cranial nerves carries only motor information optic trigeminal abducens olfactory?

abducens is the answer.

Which cranial nerve Innervates most of the visceral organs which cranial nerve Innervates most of the visceral organs vagus hypoglossal Abducens accessory?

The vagus nerve has many targets in the thoracic and abdominal cavities and innervates many of the visceral organs.

Which cranial nerve is responsible for regulating visceral activity?

The nucleus of the solitary tract (NST) is the main visceral sensory nucleus in the brainstem. It receives GVA input from glossopharyngeal and vagus nerves and sends output to parasympathetic preganglionic neurons, to premotor autonomic centers, and to the thalamus and limbic system.

Which of the following cranial nerves carries only sensory information which of the following cranial nerves carries only sensory information?

Which of the following cranial nerves carries only sensory information? Olfactory A purely sensory nerve, the olfactory nerve carries afferent impulses for the sense of smell.

What is 6th cranial nerve?

It’s also known as the abducens nerve. … The sixth cranial nerve sends signals to your lateral rectus muscle. This is a small muscle that attaches to the outer side of your eye. When this muscle contracts, your eye moves away from your nose. Each eye has its own lateral rectus muscle served by its own cranial nerve.

What is Pneumogastric nerve?

The vagus nerve, historically cited as the pneumogastric nerve, is the tenth cranial nerve or CN X, and interfaces with the parasympathetic control of the heart, lungs, and digestive tract. It actually comprises two nerves—the left and right vagus nerves—but they are typically referred to collectively in the singular.

Is cranial nerve 1 motor or sensory?

Table of cranial nerves
No. Name Sensory, motor, or both
I Olfactory Purely sensory
II Optic Sensory
III Oculomotor Mainly motor
IV Trochlear Motor

What is fifth cranial nerve?

The trigeminal nerve is the fifth cranial nerve (CN V). Its primary function is to provide sensory and motor innervation to the face. … The ophthalmic nerve is responsible for sensory innervation of the face and skull above the palpebral fissure as well as the eye and portions of the nasal cavity.

What are the 12 cranial nerve?

In higher vertebrates (reptiles, birds, mammals) there are 12 pairs of cranial nerves: olfactory (CN I), optic (CN II), oculomotor (CN III), trochlear (CN IV), trigeminal (CN V), abducent (or abducens; CN VI), facial (CN VII), vestibulocochlear (CN VIII), glossopharyngeal (CN IX), vagus (CN X), accessory (CN XI), and …

What is the 4th cranial nerve?

The fourth cranial nerve controls the actions of one of the external eye muscles, the superior oblique muscle. This muscle runs from the back of the eye socket to the top of the eye. It passes through a loop of tissue near the nose known as the trochlea. It turns the eye inward and downward.

What is the name of the tenth cranial nerve?

The vagus nerve
The vagus nerve (cranial nerve [CN] X) is the longest cranial nerve in the body, containing both motor and sensory functions in both the afferent and efferent regards.

What is the name of cranial nerve VII?

The facial nerve
The facial nerve is the seventh cranial nerve (CN VII). It arises from the brain stem and extends posteriorly to the abducens nerve and anteriorly to the vestibulocochlear nerve.

What is the lingual nerve?

The lingual nerve is one of the sensory branches of the mandibular division of the trigeminal nerve. [5] It contains general somatic afferent nerve fibers and, after chorda tympani joins it, also carries general visceral efferent nerve fibers and special visceral afferent fibers.

Which organs 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.

What nerve innervates the diaphragm?

The phrenic nerve
The phrenic nerve originates from the anterior rami of the C3 through C5 nerve roots and consists of motor, sensory, and sympathetic nerve fibers. It provides complete motor innervation to the diaphragm and sensation to the central tendon aspect of the diaphragm.
