Study Notes

Cranial Nerve Dysfunction - Case Studies

Hoarse Voice and Swallowing Difficulty: A stroke patient experiencing a hoarse voice and difficulty swallowing likely has damage to Cranial Nerve X (Vagus Nerve). This nerve plays a crucial role in controlling various functions within the head and neck, including voice production and swallowing.
Lip Pucker, Smiling, and Speech Comprehension Issues: Inability to pucker lips, smile, and difficulties with speech comprehension point to potential damage in Cranial Nerve VII (Facial Nerve). This nerve controls facial muscles and aspects of taste.
Facial Sensory Loss and Mouth Sensation: A woman who experiences a loss of sensation on her face and possibly burning sensations from hot beverages is likely to be having issues with Cranial Nerve V (Trigeminal). This nerve is responsible for sensation in the face and mouth, as well as moving chewing muscles.
Parasympathetic Control of Glands and Viscera: The Vagus nerve (CN X) contains a parasympathetic component which controls glands and viscera in both the head/neck and body.
