Study Notes
Cranial Nerves Overview
- Twelve cranial nerves (CNs) are responsible for various sensory and motor functions.
Cranial Nerve Functions
- CN I (Olfactory): Smell
- CN II (Optic): Vision
- CN III (Oculomotor): Eye movement, pupil reflex
- CN IV (Trochlear): Eye movement (looking down, medial-lateral movement)
- CN V (Trigeminal): Sensation in face, eyes, inside mouth; chewing
- CN VI (Abducens): Eye movement (lateral movement)
- CN VII (Facial): Facial expressions, taste (part of tongue)
- CN VIII (Vestibulocochlear): Hearing and balance
- CN IX (Glossopharyngeal): Throat sensation, taste (part of tongue), swallowing, blood pressure, saliva
- CN X (Vagus): Regulates digestion, blood pressure, heart rate, breathing, mood, saliva. Main parasympathetic nerve.
- CN XI (Accessory): Neck and shoulder movement
- CN XII (Hypoglossal): Tongue movement
Conditions Impacting Cranial Nerve Function
- Traumatic brain injury (TBI)
- Neurological conditions (neuropathy, ALS)
- Brain swelling/tumors/blood vessel pressure
- Stroke (CVA)
- Circulatory issues
- Infections (herpes, shingles)
- Autoimmune diseases
- Accidental damage from surgery
- Cranial nerve palsies
Cranial Nerves for Speech and Swallowing
- CN V (Trigeminal): Crucial for chewing and oral sensation.
- CN VII (Facial): Vital for facial expressions, critical in speech production.
- CN IX (Glossopharyngeal): Important for swallowing and taste.
- CN X (Vagus): Essential for various functions including swallowing.
- CN XII (Hypoglossal): Critical for tongue movement in speech and swallowing.
Importance of Cranial Nerve Assessment in Speech-Language Pathology (SLP)
- Cranial nerve assessment helps identify neurological problems.
- SLPs can diagnose potential weakness, paralysis, tongue movement difficulties, or oral cavity sensory issues via this assessment.
- Awareness of cranial nerve function is crucial for effective treatment planning. This allows for treatment focused on strengthening or awareness.
