Larynx01:21

Larynx

4.0K
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

436
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...

Cardiopulmonary Resuscitation II: ACLS Airway Management

487
Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...

The Hyoid Bone01:12

The Hyoid Bone

4.5K
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...

Pharynx01:20

Pharynx

5.8K
The pharynx, a tubular structure framed by skeletal muscle and lined with mucous membrane, extends continuously from the nasal cavities. It is segmented into three major areas: the nasopharynx, oropharynx, and laryngopharynx.
Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...

Tracheostomy Care II: Procedure

1.2K
Tracheostomy care is an essential nursing skill that involves cleaning and maintaining a tracheostomy tube to prevent infection and other complications. Here's a step-by-step guide explaining each procedure with its rationale. Note that disposable gloves are to be worn at all times and changed as often as needed to maintain a sterile work environment, and to protect both patient and healthcare worker.
Step 1: Perform hand hygiene, and put on personal protective equipment: gown, gloves, mask...

Área de la Ciencia:

  • Salud Vocal
  • Logopedia
  • Psicología

Sus antecedentes:

  • La protección laríngea carece de una definición clínica clara.
  • Puede representar un bloqueo inconsciente en la rehabilitación de la voz.
  • Limita el canto y el habla eficientes.

Objetivo del estudio:

  • Definir la protección laríngea.
  • Examinar su papel en los trastornos de la voz.
  • Explorar su conexión con estrategias protectoras inconscientes.

Principales métodos:

  • Revisión narrativa de la literatura existente.
  • Integración de hallazgos de la ciencia del dolor, el miedo-evitación, el psicoanálisis y los trastornos de la voz funcionales.
  • Exploración teórica de los fundamentos fisiológicos y psicológicos.

Principales resultados:

  • La protección laríngea existe en un continuo desde comportamientos reflejos hasta aprendidos.
  • La disfonía funcional persistente puede deberse a estrategias protectoras inconscientes.
  • La ansiedad anticipatoria, el trauma y la hipervigilancia pueden causar una cocontracción laríngea desadaptativa.
  • La laringe puede pasar a un estado defensivo, dominante del simpático.

Conclusiones:

  • La protección laríngea es una contracción sostenida desadaptativa, no solo una pérdida de la función parasimpática.
  • Los terapeutas y educadores pueden identificar y abordar la protección laríngea.
  • Superar la protección es crucial para la rehabilitación de la voz y la función vocal óptima.
