    Study Notes

    Position of the Sulcus Terminalis

    • The sulcus terminalis is located on the dorsal surface of the tongue, creating a V-shaped groove.
    • It marks the boundary between the anterior two-thirds (body) and the posterior one-third (root) of the tongue.

    Tongue Muscle Attachments

    • The tongue is anchored to various structures including the mandible, hyoid bone, and the soft palate.
    • Muscles of the tongue allow for precise movements necessary for functions like speech and swallowing.

    Characteristics of the Dorsal Surface (Dorsum) of the Tongue

    • The dorsum features papillae, which are small, raised structures that contain taste buds.
    • The surface is covered by a stratified squamous epithelium, which is rugged and can withstand abrasion.

    Part of the Tongue Resting on the Mouth Floor

    • The anterior two-thirds of the tongue rests on the floor of the mouth, allowing for easy access during various functions.

    Functions of the Tongue

    • The tongue plays a critical role in taste perception, aiding in the process of digestion and speech.
    • It also assists in manipulating food for chewing and swallowing, showcasing its versatility in oral functions.
