Human Model – Tongue, on Base

Quick Answer: The human tongue model on base is an enlarged anatomical model of the tongue mounted on a display base. It is used to teach the surface papillae and taste buds, the muscles that shape and move the tongue, and the tongue’s roles in taste, chewing, swallowing and speech.

Surface of the Tongue, Enlarged

An enlarged tongue model makes the tongue’s rough surface readable. The upper surface is covered by papillae of four kinds: fine, thread-like filiform papillae all over, which grip food but have no taste buds; mushroom-shaped fungiform papillae scattered among them, especially near the tip and edges; a V-shaped row of large circumvallate papillae at the back; and leaf-like foliate papillae in folds on the sides. The V-shaped groove behind the circumvallate row, the sulcus terminalis, divides the front two-thirds of the tongue from the back third.

Taste buds sit mainly in the fungiform, circumvallate and foliate papillae. A common classroom error is the tongue map, which claims each taste is sensed on one zone only. In fact receptors for sweet, salty, sour, bitter and umami are found in taste buds across all the regions that carry them, and a model is a good prompt for correcting that misconception with a simple tasting activity.

Beneath the surface, the tongue is almost entirely muscle. Intrinsic muscles within it change its shape for speech and moving food, and extrinsic muscles anchor it to the jaw, the hyoid bone and the skull to change its position. How much of this the model shows, and whether the base includes the floor of the mouth or throat, should be confirmed; the human larynx model continues the story into the airway.

Specifications

Applications

• Lessons on the sense of taste and the location of taste buds
• Correcting the tongue map misconception with a tasting investigation
• Speech and language therapy training on tongue movement
• Explaining the swallowing sequence in nursing and allied health courses

Care & Handling

• Keep the tongue model on its base when not being handled, and hold it by the base when moving it.
• Use a soft brush to clean the textured papillae surface, then a barely damp cloth if needed.
• Store it covered to keep dust out of the fine surface texture.

Why Choose LabEquip

Biology teachers and speech therapy trainers choose an enlarged tongue because papillae are hard to see on a real one. It forms part of LabEquip’s biology lab products; ask about scale through the LabEquip contact page.

Frequently Asked Questions

Is the tongue map correct?

No. The idea that each taste is detected on only one part of the tongue is a myth. Taste buds sensitive to all five basic tastes are found across the regions of the tongue that carry taste buds.

What are the five basic tastes?

Sweet, salty, sour, bitter and umami, the savoury taste of foods such as broth and aged cheese. Much of what we call flavour also depends on smell.

Which papillae do not have taste buds?

The filiform papillae, the most numerous kind, have no taste buds. They give the tongue its rough texture and help grip food.

Why is the tongue so mobile?

It is almost all muscle. Intrinsic muscles change its shape and extrinsic muscles move it forward, back, up and down, which is essential for speech, chewing and swallowing.

What are the circumvallate papillae?

They are large, round papillae arranged in a V-shaped row near the back of the tongue. Each is surrounded by a trench and contains many taste buds.

Who uses a tongue model?

Biology teachers covering the senses, speech and language therapy trainers, dental and nursing courses, and health educators explaining taste and swallowing.
