What causes 5th cranial nerve palsy?
A cranial nerve palsy can occur due to a variety of causes. It can be congenital (present at birth), traumatic, or due to blood vessel disease (hypertension, diabetes, strokes, aneurysms, etc). It can also be due to infections, migraines, tumors, or elevated intracranial pressure.
How many cranial nerves are present in Scoliodon?
Ten pairs of cranial nerves arise from the brain at different locations to supply the anterior region of the body. In addition to them a pair of terminal or pre olfactory nerves (zero nerves) arises from the ventral surface of the cerebrum.
What is the most common cranial nerve palsy?
Abducens (sixth cranial) nerve palsy is the most common ocular motor paralysis in adults and the second-most common in children. The abducens nerve controls the lateral rectus muscle, which AB-ducts the eye. Abducens nerve palsy causes an esotropia due to the unopposed action of the antagonistic medial rectus muscle.
What are the symptoms of vagus nerve damage?

What happens if cranial nerve 5 is damaged?
A trigeminal nerve injury may affect a small area, like part of your gum, or a large area, like one side of your face. The injury can cause problems with chewing and speaking. The extent depends on where the nerve damage occurs. You may have ongoing numbness or facial pain in the area that the nerve serves.
Does brain MRI show cranial nerves?
Cranial nerve dysfunctions may be the result of pathological processes of the cranial nerve itself or be related to tumors, inflammation, infectious processes, or traumatic injuries of adjacent structures. Magnetic resonance imaging (MRI) is considered the gold standard in the study of the cranial nerves.
Which is the largest nerve in Scoliodon?
This system is made up of a series of paired ganglia arranged irregularly on the dorsal wall of the kidney and the posterior cardinal sinuses. The gastric ganglion is the largest ganglion and sends nerves to the viscera.

What is LR palsy?
Sixth nerve palsy occurs when the sixth cranial nerve is damaged or doesn’t work right. It’s also known as the abducens nerve. This condition causes problems with eye movement. 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.
