During a clinical examination any deviation of the tongue may indicate a problem with this nerve. Deviation of the tongue is always to the side of the lesion initially.

===Spinal Cord===
The '''spinal cord''' is constructed of the ''[[Spinal Cord - Anatomy & Physiology#Marginal layer|marginal layer]] ''which has axons and white matter, the ''[[Spinal Cord - Anatomy & Physiology#Mantle|mantle]]'' which contains cell bodies and grey matter and the ''[[Spinal Cord - Anatomy & Physiology#Spinal Canal|spinal canal]]''. This canal conducts sensory information from the peripheral nervous system (both somatic and autonomic) to the brain, conducts motor information from the brain to various effectors and acts as a minor reflex center. The spinal cord can be divided to several regions:

The spinal cord can be divided to several regions:
Large amounts of CSF are drained into venous sinuses through arachnoid granulations in the '''dorsal sagittal sinus'''. The dorsal sagittal sinus is located between the folds of dura, known as the '''falx cerebri''', covering each of the cerebral hemispheres. Arachnoid granulations contain many villi that are able to act as a one way valve helping to regulate pressure within the CSF, and these '''arachnoid villi''' push through the dura and into the venous sinuses.
