Flashcards
Olfactory Nerve (CN I)
Olfactory Nerve (CN I)
The olfactory nerve (CN I) is responsible for the sense of smell. It transmits olfactory information from the nasal cavity to the brain.
Optic Nerve (CN II)
Optic Nerve (CN II)
The optic nerve (CN II) carries visual information from the eyes to the brain.
Oculomotor Nerve (CN III)
Oculomotor Nerve (CN III)
The oculomotor nerve (CN III) controls most eye movements, including pupil constriction and eyelid opening.

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.
