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,...

Anatomy of Respiratory System I: Upper Respiratory Tract

4.6K
The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract....

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...

Anatomy of Respiratory System II: Lower Respiratory Tract01:31

Anatomy of Respiratory System II: Lower Respiratory Tract

3.2K
The lower respiratory tract is anatomically composed of several vital structures, including the larynx, trachea, bronchial tree, alveoli, lungs, and pleurae. Each component has a specific function, and all are intricately connected to ensure efficient respiration.
The Larynx
It is located between the pharynx and the trachea, acts as a passageway for air, and hosts several critical structures, such as the epiglottis, vocal cords, and glottis. The epiglottis acts as a gateway, guiding food to the...

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...

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques01:30

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...

Area of Science:

  • Anatomy
  • Radiology
  • Anthropology

Background:

  • The larynx exhibits notable sex-related anatomical variations.
  • Previous studies often focused on isolated laryngeal features, limiting comprehensive understanding.

Purpose of the Study:

  • To comprehensively analyze in vivo laryngeal dimensions using computed tomography (CT).
  • To establish reference values for laryngeal parameters and clarify their relationships with sex and age.
  • To investigate sexual dimorphism in laryngeal morphology.

Main Methods:

  • Retrospective analysis of 157 neck CT scans (67 males, 90 females).
  • Morphometric measurements included laryngeal length, cartilaginous dimensions, epiglottic measurements, and pre-epiglottic space volume.
  • Statistical analysis using Mann-Whitney U tests for sex and age differences.

Main Results:

  • Significant sex-related differences observed in most laryngeal parameters, especially epiglottic length, laryngeal length, thyroid angle, and thyroid lamina height.
  • Epiglottic length was the strongest predictor of total laryngeal length (R² = 0.74).
  • Age had minimal effects, with slight decrease in epiglottic angle and influence on pre-epiglottic space volume.

Conclusions:

  • This study provides comprehensive in vivo data on laryngeal dimensions, establishing reference values.
  • Findings confirm significant sexual dimorphism in laryngeal morphology.
  • The data serve as a valuable resource for clinical and anatomical studies.
