Study Notes
Tongue Structure and Function
- The tongue is primarily composed of skeletal muscle.
- Intrinsic muscles or lingual muscle proper are responsible for changing the shape of the tongue.
- Intermediate layer of the tongue contains closely packed serous glands.
Nerve Supply
- The lingual nerve carries general sensation (pain, temperature, and tactile sensation) to the rostral two-thirds of the tongue.
- The chorda tympani nerve carries the sense of taste to the rostral two-thirds of the tongue.
- The hypoglossal nerve provides motor innervation to the intrinsic and extrinsic lingual muscles.
Papillae
- Vallate papillae are located on the dorsal surface of the tongue.
- Foliate papillae are characterized by folds or ridges on the lateral surface of the tongue.
- Fungiform papillae contain taste buds on the dorsal surface of the tongue.
Blood Supply
- The lingual artery is responsible for supplying blood to the tongue.
Larynx
- The lateral cricoarytenoid muscle is responsible for adducting the two arytenoid cartilages.
- The vocal ligament extends between the thyroid and cricoid cartilages.
- The blood supply of the larynx is provided by the superior and inferior laryngeal arteries.
Other
- In carnivores, the lyssa is a rod-shaped fibrous body found in the rostral part of the tongue.
- In cattle, a prominent papilla is formed on the dorsal surface of the tongue.
- The tongue attaches to the hyoid bone.
- Minor salivary glands are present in the oral cavity and produce mucous secretion.
