The trigeminal nerve, CN V, is the fifth paired cranial nerve. It is also the largest cranial nerve. In this article, we shall look at the anatomical course of the nerve, and the motor, sensory and parasympathetic functions of its terminal branches.he trigeminal nerve, CN V, is the fifth paired cranial nerve.

Acquired deafness contrasts to congenital deafness which is present at birth. The distinction between acquired and congenital deafness specifies only the time that the deafness appears. It does not specify whether the cause of the deafness is genetic (inherited). Acquired deafness may or may not be genetic. For example, it may be a manifestation of a delayed-onset form of genetic deafness.
Congenital myopathy. Congenital myopathy is a very broad term for any muscle disorder present at birth. This defect primarily affects skeletal muscle fibres and causes muscular weakness and/or hypotonia. Congenital myopathies account for one of the top neuromuscular disorders in the world today, comprising approximately 6 in 100,000 live births every year. As a whole, congenital myopathies can be broadly classified as follows: A distinctive abnormality in skeletal muscle fibres on the cellular level; observable via light microscope; Symptoms of muscle weakness and hypotonia; Is a congenital disorder, meaning it occurs during development and symptoms present themselves at birth or in early life.
