CN 7: Facial Nerve
- seventh (VII) of twelve paired [|cranial nerves]. - emerges from the brainstem between the [|pons] and the [|medulla]controls the muscles of facial expression, and functions in the conveyance of [|taste] sensations from the anterior two-thirds of the [|tongue] and oral cavity. - connected to head and neck [|ganglia]( [|biological tissue] mass, most commonly a mass of [|nerve cell] bodies) 

CN 5: Trigeminal Nerve
- the **fifth [|cranial nerve]**, also called the **fifth nerve**, or **CNV** or **CN5 -** responsible for sensation in the face - Sensory information from the face and body is processed by parallel pathways in the central nervous system - controls //motor//functions (biting, chewing, and swallowing).

Stroke and Expression
- loss of brain function. - caused by the interruption of flow of blood to the brain (ischemic stroke) or the rupture of blood vessels in the brain (hemorrhagic stroke). - causes brain cells (neurons) in the affected area to die, resulting in the inability to move different muscles.

This raises the question of whether expression can be done without the ability to move different facial muscles, and in turn interpret or feel different emotions? This branches from the theory earlier stated if emotion is felt first then expressed or the opposite.
