Warning Signs Of Bell's Palsy

Facial Muscle Twitches

When the function of the seventh cranial nerve is disrupted, it can also cause twitching in facial muscle. This can be the result of nerve compression against a section of bone, or because of inflammation. This cranial nerve, like all nerves, has a protective coating consisting of a fatty substance called myelin, called the myelin sheath. This sheath is essential for normal nerve function. When the myelin is damaged, it's similar to a damaged electrical cord. When an electrical cord isn't intact, it can't conduct electricity smoothly. Something similar happens with the cranial nerve, as when the myelin sheath isn't intact, signals from the brain can't travel along properly. The brain's signal is interrupted like a short in a cord. The result can be the twitchy facial muscle movements seen in some patients with Bell's palsy.
