Cranial Nerve Palsies

Nerves connected to every part of our head, face, and trunk through our brain are known as cranial nerves. There are 12 pairs of carnival nerves, and other than this, some are involved in special senses (sight, smell, hearing, taste, feeling) while others control muscles and glands. Due to carnival nerve palsies, many body parts don’t function well. We have mentioned many cranial nerve palsies symptoms in this article, which will help you know if you face a problem related to cranial nerve palsies. Different names are there for each pair of cranial nerve palsies.

What are cranial nerves? 

The cranial nerves are present in our head, face, and trunk, and the brain directly controls them. There are 12 pairs of cranial nerves where some are involved with sense organs like sight, smell, hearing, taste, and feeling, while others control muscles and glands. Names of all the 12 pair cranial nerves are:- 

• 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)
• hypoglossal (CN XII)

Through motor neurons and sensory neurons, cranial nerves are maid. The longest and the most complex cranial nerve is known as the vagus nerve. The other cranial nerve names are X cranial nerve and the 10th cranial nerve.

Olfactory nerve

These nerves help transmit the sense of smell of a person to the brain. Inhaled aromatic molecules are transmitted to the olfactory bulb by olfactory receptors in the nasal passage. 

Optic nerve

Here optic nerve helps the human body with a person’s vision, and these nerves share information related to vision. This nerve works in simple principles like when lights hit the retina of the eyes, which contains rods and cones. The photoreceptors create a visual effect for the brain. 

Oculomotor nerve

This nerve helps to control the movement of muscles in the eyes. The Oculomotor provides movement to the eyes’ muscles that help move the eyes ball and upper eyelid, known as extraocular muscles. 

Trochlear nerve

This nerve is also involved in the help of the muscles of the eyes. 

Trigeminal nerve

The trigeminal nerve is the largest nerve of the cranial nerve; it has both motor and sensory functions. The motor function, which is present in the trigeminal, helps the person chew and provides sensation to the ear’s tympanic membrane.

Abducens nerve

The abducens nerve also helps control eye movements. Turning the gaze outward helps the lateral rectus muscle, one of the extraocular muscles.

Facial nerve

The facial nerve also has both motor and sensory functions. There’s a nerve made up of four nuclei that serve different functions like this helps produce facial expressions through the movement of facial muscles; this nerve also provides a sensation to the external ear and taste. 

Vestibulocochlear nerve

This nerve transfers the sound from the inner ear to the brain and balances the information.

Glossopharyngeal nerve

This organ receives sensory input from your middle ear, tonsil, pharynx, and other tongue parts.

Vagus nerve 

You can sweat, regulate your heart rate, move the muscles in your mouth, and breathe normally because of the vagus nerve. 

Spinal accessory 

A spinal accessory controls the specific functions of your neck and shoulders.

Hypoglossal nerve

This nerve controls the movements of our mouth, like the movement for speech, eating, and swallowing.

Cranial Nerve Palsies Symptoms

Cranial nerve palsies symptoms are simple, and any person can face this at any age; the symptoms are as follow 

• Disparate aches and pains in the body
• When touched, the skin becomes sensitive
• Vertigo
• Loss of smell
• Problems with speech

Treatments for Cranial Nerve Disorders

Some cranial nerve disorders can resolve on their own. Your medical provider may also prescribe medications to treat your neuropathy. Your provider may also suggest surgery to repair the damage. It is important to get tested for and treated for cranial nerve disorders since they can cause extensive damage.

Conclusion 

In this article, we have covered information related to cranial nerve palsies, cranial nerve palsies symptoms, and many more topics. There are 12 pairs of carnival nerves, which each have a number corresponding to their location in the brain and a name that describes their function. Scientists use Roman numerals from I–XII to label the cranial nerves in the brain. As in this every a group person can face nerve palsies and if you feel like any symptom match with you should visit the hospital first as some time this problems grow a lot and give many problems.
