====Brainstem====
{{Main|Brainstem}}
The brainstem lies beneath the cerebrum and consists of the [[midbrain]], [[pons]] and [[medulla oblongata|medulla]]. It lies in the [[posterior cranial fossa|back part of the skull]], resting on the part of the [[base of the skull|base]] known as the [[clivus (anatomy)|clivus]], and ends at the [[foramen magnum]], a large [[:wikt:foramen|opening]] in the [[occipital bone]]. The brainstem continues below this as the [[spinal cord]],{{sfn|Gray's Anatomy|2008|p=275}} protected by the [[vertebral column]].

Ten of the twelve pairs of [[cranial nerve]]s{{efn|Specifically the [[oculomotor]], [[trochlear nerve]], [[trigeminal nerve]], [[abducens nerve]], [[facial nerve]], [[vestibulocochlear nerve]], [[glossopharyngeal nerve]], [[vagus nerve]], [[accessory nerve]] and [[hypoglossal nerve]]s.{{sfn|Gray's Anatomy|2008|p=275}}}} emerge directly from the brainstem.{{sfn|Gray's Anatomy|2008|p=275}} The brainstem also contains many [[cranial nerve nucleus|cranial nerve nuclei]] and [[nucleus (neuroanatomy)|nuclei]] of [[nerve|peripheral nerves]], as well as nuclei involved in the regulation of many essential processes including [[breathing]], control of eye movements and balance.{{sfn|Guyton & Hall|2011|p=691}}{{sfn|Gray's Anatomy|2008|p=275}} The [[reticular formation]], a network of nuclei of ill-defined formation, is present within and along the length of the brainstem.{{sfn|Gray's Anatomy|2008|p=275}} Many [[nerve tract]]s, which transmit information to and from the cerebral cortex to the rest of the body, pass through the brainstem.{{sfn|Gray's Anatomy|2008|p=275}}
