Summary
Visual feedback significantly enhances tongue strength in healthy adults. This finding suggests visual cues can be an effective method for improving tongue muscle power.
Area of Science:
- Speech-Language Pathology
- Neurology
- Biomechanics
Background:
- Tongue strength is crucial for various oral functions like swallowing and speech.
- Understanding factors influencing tongue strength is important for rehabilitation and performance enhancement.
- Visual feedback is a known modulator of motor control in other body parts.
Purpose of the Study:
- To determine if visual feedback impacts anterior tongue strength in healthy adults.
- To quantify the difference in tongue strength with and without visual feedback.
Main Methods:
- Thirty healthy adults participated in the study.
- Tongue strength was measured using the Iowa Oral Performance Instrument.
- Measurements were taken both with and without visual feedback applied.
Main Results:
- Mean tongue strength was 45.5 ± 9.3 kPa with visual feedback.
- Mean tongue strength was 41.1 ± 8.6 kPa without visual feedback.
- A statistically significant difference was observed between the two conditions.
Conclusions:
- Visual feedback appears to be an effective method for increasing tongue strength.
- This finding has potential implications for therapies aimed at improving oral motor function.

Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

The human tongue is a fascinating and complex organ, responsible for various essential functions such as swallowing, speech, and taste. It is also subject to various conditions and diseases. In this article, we delve into the anatomy of the tongue, its roles, and some common conditions that can affect it.
Anatomical Position in the Oral Cavity
The tongue is located within the oral cavity, also known as the mouth. It is attached to the floor of the mouth by a fold of mucous membrane called the...

The tip-of-the-tongue (TOT) phenomenon is a cognitive experience characterized by a temporary inability to retrieve specific information from memory despite having a strong feeling of knowing the information. Although individuals cannot access the target word or detail, they frequently recall related elements, such as its initial letter, syllable count, or context. This partial retrieval often causes frustration, as one might recognize a familiar face or know that a name starts with a specific...

In most cases, excessive hormone production is prevented by negative feedback—a loop that starts with a stimulus inducing the release of a particular substance, like a hormone, to maintain a certain level before triggering a signal that results in a decrease in further release of the hormone.

00:49The Tongue and Taste Buds
41.2K
The surface of the tongue is covered with various small bumps called papillae, which either distribute what has been ingested (filiform papillae) or contain the sensory taste (or gustatory) receptor cells (fungiform, circumvallate, and foliate papillae). Embedded within each taste-related papilla are the taste buds—clusters of 30 to 100 gustatory receptor cells.

Binary Acids and Bases
In the absence of any leveling effect, the acid strength of binary compounds of hydrogen with nonmetals (A) increases as the H-A bond strength decreases down a group in the periodic table. For group 17, the order of increasing acidity is HF < HCl < HBr < HI. Likewise, for group 16, the order of increasing acid strength is H2O < H2S < H2Se < H2Te. Across a row in the periodic table, the acid strength of binary hydrogen compounds increases with increasing...
