What are the 3 parts of the larynx?
The larynx, commonly called the voice box or glottis, is the passageway for air between the pharynx above and the trachea below. It extends from the fourth to the sixth vertebral levels. The larynx is often divided into three sections: sublarynx, larynx, and supralarynx.
What are the major structures of the larynx?
The larynx is composed of three large unpaired cartilages (cricoid, thyroid, and epiglottis) and three paired smaller cartilages (arytenoid, corniculate, and cuneiform), making a total of nine individual cartilages. The thyroid cartilage is the largest of the laryngeal cartilages and is composed of hyaline cartilage.
What is attachment at oblique line of thyroid lamina?
The oblique line is a line on the thyroid cartilage. It marks the upper lateral borders of the thyroid gland. Two muscles originate along the line, the thyrohyoid muscle and inferior pharyngeal constrictor. The sternothyroid inserts along the line.
What structure is known as the Adam’s apple?
“Adam’s Apple” is the colloquial term used to describe what is officially named the laryngeal prominence of the thyroid cartilage.
What is the pharynx anatomy?
The pharynx, commonly called the throat, is a passageway that extends from the base of the skull to the level of the sixth cervical vertebra. It serves both the respiratory and digestive systems by receiving air from the nasal cavity and air, food, and water from the oral cavity.
What is the larynx lined with?
The lumen of the larynx is lined mainly with respiratory epithelium, consisting of ciliated, pseudostratified columnar epithelium with a rich population of goblet cells, and a submucosa containing mixed mucous and serous glands.
What is the function of the vocal folds?
Briefly, the vocal folds are folds of tissue located in the larynx (voicebox) that have three important functions: To protect the airway from choking on material in the throat. To regulate the flow of air into our lungs. The production of sounds used for speech.
What is thyroid lamina?
The thyroid cartilage is composed of two plates, called laminae, that join in the front at an angle of 90 to 120 degrees. The protrusion it creates, visible on the front of the neck, is generally more prominent in men because of a sharper angle in males.
Do women’s have Adam’s apple?
Everyone’s larynx grows during puberty, but a girl’s larynx doesn’t grow as much as a boy’s does. That’s why boys have Adam’s apples. Most girls don’t have Adam’s apples, but some do. Actually, girls’ voices get a little bit deeper as their larynxes get larger, too.
Is Adam’s apple attractive?
“Personally I find Adam’s apples extremely attractive in guys, right up there with jawline and abs,” wrote back one respondent, adding that prominent Adam’s apples have adorned the throats of male statues for centuries, dating all the way to Greek and Roman masterpieces that sought to display the male body in peak form …
What is the function of larynx pharynx?
The throat (pharynx and larynx) is a ring-like muscular tube that acts as the passageway for air, food and liquid. It is located behind the nose and mouth and connects the mouth (oral cavity) and nose to the breathing passages (trachea [windpipe] and lungs) and the esophagus (eating tube).
Where is the larynx located?
The larynx extends from the upper border of the epiglottis to the lower border of the cricoid cartilage. Above, it communicates with the laryngo-pharynx through the laryngeal inlet and below, with trachea.
What is the upper margin of the larynx?
The upper end or margin is free, covered with mucous membrane and forms the upper boundary of the inlet of larynx. The lower end is connected to the posterior surface of thyroid angle by the thyro-epiglottic ligament.
What type of epithelium lines the larynx?
The larynx is essentially lined by the ciliated pseudo-stratified columnar epithelium, except the following areas which are lined by stratified squamous epithelium— aryepiglottic fold, vocal fold and the upper part of the posterior surface of epiglottis.
