MAXIMUM PROTRUSIVE TONGUE FORCE IN HEALTHY YOUNG ADULTS.
Summary
This study quantified maximum tongue protrusion force in healthy Brazilian adults using a new instrument. Men exhibited significantly higher tongue force than women, highlighting gender-based differences in this biomechanical measure.
Area of Science:
- Biomechanics
- Speech-Language Pathology
Background:
- Clinical assessment of tongue force is typically qualitative.
- A novel instrument was developed to quantify tongue force objectively.
Purpose of the Study:
- To quantify maximum tongue protrusion force in Brazilian adults with normal tongue strength.
- To compare tongue force values between male and female participants.
Main Methods:
- 105 healthy adults (43 men, 62 women, aged 18-29) underwent quantitative tongue force evaluation.
- A newly developed instrument measured maximum tongue protrusion force.
- Participants were selected based on normal tongue strength via qualitative assessment.
Main Results:
- The mean maximum tongue force across all participants was 17.58 ± 7.95 N.
- Significant differences in median tongue force were found between genders, with men showing higher values.
- High intersubject variability was observed, indicated by large variation coefficients.
Conclusions:
- The developed instrument provides quantitative tongue force data.
- Gender differences in maximum tongue protrusion force were confirmed.
- The instrument shows promise for reliable intrasubject comparisons, particularly in clinical follow-up scenarios.

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...

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

01:25Deglutition
7.4K
Swallowing, otherwise known as deglutition, facilitates the transport of food from the mouth to the stomach. It is a multifaceted process that involves both the tongue and the muscles of the throat and esophagus. Saliva and mucus aid in this process, which takes approximately 4 to 8 seconds for semi-solid or solid food and around 1 second for liquids or very soft food.
Swallowing can be divided into three stages: the voluntary phase, the pharyngeal phase, and the esophageal phase. Although the...

In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

00:49The Tongue and Taste Buds
42.0K
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.

01:12The Hyoid Bone
6.2K
The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...
