What is the function of cranial nerve?

The functions of the cranial nerves are sensory, motor, or both:

• Sensory cranial nerves help a person to see, smell, and hear.
• Motor cranial nerves help control muscle movements in the head and neck.

What is a function of cranial nerve Five?

The trigeminal nerve is the fifth cranial nerve (CN V). Its primary function is to provide sensory and motor innervation to the face.

What do the 12 cranial nerves do?

Twelve nerves known as the cranial nerves allow the brain to control the most important functions of the body. These include eye movement, sense of smell, and taste. Most of the cranial nerves are related to facial movement, but some control parts of the body like the digestive system and heartbeat.

What are the 12 nerves of the brain?

The twelve paired cranial nerves are the olfactory, optic, oculomotor, trochlear , trigeminal, abducent, facial, vestibulocochlear, glossopharyngeal , vagal, accessory, and hypoglossal nerves. Synonym(s): nervi craniales [TA] .

Are the 12 pairs of cranial nerves mixed nerves?

These 12 cranial nerves carry different fiberes. Most of them are sensory fibers but some are motor and other are mixed as well. Out of these 12 pairs of cranial nerves, 2 arise from cerebrum while the other from brain stem. These nerves are termed according to their structure or functions.

What are the cranial nerve names?

The names of the cranial nerves (CN) are: CN I – olfactory, CN II – optic, CN III – oculomotor, CN IV – trochlear, CN V – trigeminal, CN VI – abducens, CN VII – facial, CN VIII – vestibulocochlear, CN IX – glossopharyngeal, CN X – vagus, CN XI – accessory, and CN XII – hypoglossal.
