WebThe central processes enter the brain via the fifth cranial nerve and terminate in the principal (or chief) sensory nucleus of the trigeminal complex (or of the fifth nerve). The second-order cells in this nucleus send axons across the midline to form the dorsal trigeminothalamic tract , also known as the trigeminal lemniscus . WebLUCI can affect both the vagus and trigeminal nerves, as the trigeminocervical nucleus goes down to the C2 level in the spinal cord. When sound waves are unable to be conducted because of fluid in the middle ear from Eustachian tube dysfunction, the mechanical vibrations from sound are not transmitted to the cochlear perilymph and endolymph. nadine henry-thomas
