Resumen
Los hablantes de español retraen su raíz de la lengua cuando producen el trillo alveolar /r/. Este movimiento posterior de la lengua es crucial para la producción y el desarrollo del habla eficaz, similar al inglés /ɹ/.
Área de la Ciencia:
- La lingüística
- Ciencias del habla
- Fonética
Sus antecedentes:
- Las descripciones articuladoras del trillo alveolar / r / a menudo pasan por alto los movimientos posteriores de la lengua.
- Comprender la dinámica de la raíz de la lengua es vital para el control y el desarrollo del motor del habla.
Objetivo del estudio:
- Investigar el papel de la lengua posterior en la producción del trillo alveolar español.
- Para caracterizar el movimiento de la raíz de la lengua durante la producción de /r/ utilizando imágenes de ultrasonido.
Principales métodos:
- Se emplearon imágenes de ultrasonido para capturar los movimientos de la lengua durante la articulación /r/.
- Se reclutaron para el estudio adultos de habla hispana.
Principales resultados:
- Los hablantes de español retraen su raíz de la lengua mientras producen el trillo alveolar /r/.
- Esta retracción posterior de la lengua es similar a los movimientos observados para el aproximante rotativo inglés /ɹ/.
Conclusiones:
- La lengua posterior, específicamente la retracción de la raíz de la lengua, juega un papel importante en la producción de /r/ en español.
- Los hallazgos ofrecen información sobre el control motor del habla y tienen implicaciones clínicas para el desarrollo del habla.

01:26Assessment of the Mouth
401
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.

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

5.8K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

01:20Imaging Studies for Cardiovascular System II:Types of Echocardiography
395
Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...
