Tongue
Clinical pearl: A hypoglossal nerve lesion causes the protruded tongue to deviate toward the side of the lesion because the intact genioglossus pushes the tongue toward the weak side.
Eye
Caused by interruption of the sympathetic pathway. Possible causes include a Pancoast tumor, brainstem/spinal cord lesions, or carotid artery dissection. Facial flushing may occur.
Thyroid & Larynx
Exam distinction: EBSLN injury impairs tension of the vocal folds; RLN injury impairs most intrinsic laryngeal muscles.
Triangles of neck
Visual reference: the four subdivisions are separated by the digastric and omohyoid muscles.
Liver
The liver receives blood from two sources. Blood passes through hepatic sinusoids and drains into central veins, then hepatic veins and the inferior vena cava.
