Which cranial nerves carries only sensory information?
The question is asking what three cranial nerves are purely sensory in their function. Some relevant terms here are olfactory, optic, and auditory or vestibucochlear or acoustic nerves. The only three cranial nerves that are pure sensory in function are cranial nerve #1 : the olfactory nerve (smell), cranial nerve #2 : the optic nerve (sight), and cranial nerve #8 : the auditory/vestibucochlear/acoustic nerve (hearing).
The only cranial nerves to extend beyond the head and neck region are the vagus nerves?
Yes, that's correct. The vagus nerves are the only cranial nerves that extend beyond the head and neck region, reaching far into the abdomen and thorax. They are responsible for a variety of functions including regulating the heart, lungs, and digestive system.
Do cranial nerves serve structures only in the head and neck?
False
What do all cranial nerves control?
Cranial nerve V. is the trigeminal nerve. It got its name after its three branches. Two of the branches are pure sensory, the third is mixed motor and sensory. In short, it gathers sensory information from the scalp, eyelids, eyes (from the cornea and conjuntiva, NOT visual information), nose, cheeks, lips, teeth, gums, oral cavity and jaw. The motor fibers innervate muscles involved in chewing and swallowing.
Is the glossopharyngeal nerve the only cranial nerve that contains sensory fibers?
No, the glossopharyngeal nerve (CN IX) is not the only cranial nerve that contains sensory fibers. Other cranial nerves, such as the trigeminal nerve (CN V), facial nerve (CN VII), vestibulocochlear nerve (CN VIII), and vagus nerve (CN X), also contain sensory fibers in addition to motor or mixed fibers.
What is the only cranial nerve attached to the cerebrum called?
Optic
Which cranial nerve is attached to the cerebrum?
The cranial nerves that are attached to the medulla oblongata are the glossopharyngeal, vagus, accessory and hypoglossal nerves. The glossopharyngeal nerve is the ninth cranial nerve that causes the tongue, throat, and parotid gland to function properly. The vagus nerve is the tenth cranial nerve which helps with motor production, mainly regarding the process of voice production. The accessory nerve is the eleventh cranial muscle whose only function is motor function, mainly regarding the trapezius and sternocledomastoid muscles. Lastly, the hypoglossal nerve is the twelfth cranial nerve which helps in the proper functioning of the muscles under the tongue.
Which cranial nerves are not sensory?
Cranial nerves III (oculomotor), IV (trochlear), VI (abducens), XI (accessory), and XII (hypoglossal) are motor nerves only.
Is true Both spinal and cranial nerves have dorsal and ventral roots?
Dorsal and ventral roots are a feature of spinal nerves only. Cranial nerves do not have dorsal and ventral roots.
The only two cranial nerves that are completely sensory are numbers?
The only two cranial nerves that are completely sensory are the olfactory nerve (I) for smell and the optic nerve (II) for vision.
What name refers to nerves that only originate in the brain carry messages to and from structures in the head and neck and are considered part of the peripheral nervous system?
Cranial nervesCranial Nerves only originate in the brain and carry messages to and from structures in the head and neck.
Do cranial nerves serve as structures only in the head and neck?
False
Are the Vagus Nerves the only cranial nerves to extend beyond the head and neck region?
no, they are not, we are taking this test now haha

What name refers to nerves that only originate in the brain carry messages to and from structures in the head and neck and are considered part of the peripheral nervous sytem?
These are 12 pairs of nerves called the cranial nerves.
