Study Notes

Tongue Anatomy

Foliate lingual papillae: Vertical ridges located on the sides of the tongue, contributing to taste sensation.
Lingual tonsils: Positioned at the base and sides of the tongue, these are irregular masses of lymphatic tissue involved in immune response.
Body of tongue: Refers to the anterior two-thirds of the tongue, primarily responsible for taste and manipulation of food.
Base of tongue: The posterior one-third of the tongue, playing a role in swallowing and taste perception.
Dorsal surface: The top aspect of the tongue, where various papillae and taste buds are located.
Ventral surface: The underside of the tongue, which has a smooth appearance and contains blood vessels and connective tissue.
Lateral surface: The sides of the tongue where foliate papillae are found.
Apex: The tip of the tongue, important for tactile sensations and taste recognition.
Filiform lingual papillae: Slender, thread-like projections covering the dorsal surface, responsible for the texture of the tongue but do not contain taste buds.
Foramen cecum: A small pit-like depression located where the sulcus terminalis points backward, serving as a remnant of the embryonic development of the tongue.
Sulcus terminalis: A V-shaped groove that separates the base from the body of the tongue along the dorsal surface.
Circumvallate lingual papillae: Round elevations on the dorsal surface forming a V-shape, containing 10-14 taste buds crucial for detecting taste stimuli.
Median lingual sulcus: A midline depression along the dorsal surface of the tongue, contributing to its characteristic shape.
Fungiform lingual papillae: Positioned on the dorsal surface as red, mushroom-shaped dots that house taste buds, facilitating taste sensation.
