Study Notes
Intrinsic and Extrinsic Movements of the Tongue
- The intrinsic muscles of the tongue are responsible for its intrinsic movements, such as changing shape and manipulating food during mastication.
- The extrinsic muscles of the tongue, consisting of the genioglossus, hyoglossus, and styloglossus, are responsible for its extrinsic movements, such as protrusion, retrusion, and elevation.
Tongue Appearance and Associated Conditions
- A smooth tongue may indicate a deficiency in vitamin B12 or iron.
- The appearance of pigmented spots on the tongue may indicate a benign condition, such as a melanotic macule, or a malignant condition, such as oral melanoma.
- An ulcerated hemiatrophy of the tongue may indicate a lesion of the hypoglossal nerve, resulting in denervation of the tongue muscles.
