When the trachea reaches a point in the mediastinum called the carina, it splits into two tubes called the primary bronchi. Its primary function is to keep food and drink out of the airway, but it evolved the additional role of sound production (phonation) in many animals; hence, we colloquially think of it as the “voice box.” The superior opening of the larynx is guarded by a flap of tissue called the epiglottis. At rest, the epiglottis stands almost vertically. See also: Respiratory tract § Lower respiratory tract. The bronchi function to carry air that is breathed in through to the functional tissues of the lungs, called alveoli.

METHODS: The airway mucosa of the larynx, tracheal carina, and bronchi were stimulated by injection of distilled water (0.5 ml) at two different depths of sevoflurane anesthesia (1.2 and 1.8 MAC) in 11 female subjects breathing spontaneously through the laryngeal mask airway. 2017-03-15 2020-02-26 1996-08-07 2015-08-04 Physiology of cough. The cough receptors or rapidly adapting irritant receptors are located mainly on the posterior wall of the trachea, pharynx, and at the carina of trachea, the point where the trachea branches into the main bronchi.The receptors are less abundant in the distal airways, and absent beyond the respiratory bronchioles.When triggered, impulses travel via the internal laryngeal 2015-02-10 The Carina Bowls Club has several spaces available for group functions. We have the Club Hall, Panchos Pizza Restaurant, and tables and seating at the Barefoot Bowls Green. The bar is always open during functions and has very reasonably priced drinks, with a generous selection of wines, beers and spirits. Many bivalves have areas demarcated by angles or ­ridges that radiate from the umbos. The most common of these is a posterior angle or posterior ridge running over the umbos to the posterior ventral margin.

It functions as an open valve in respiration, a partially closed valve in phonation, and as a closed valve protecting against aspiration during swallowing. The larynx extends from its oblique entrance formed by the aryepiglottic folds, the tip of the epiglottis, and the posterior commissure to the lower border of the cricoid cartilage and bulges posteriorly into the laryngopharynx.

This is the most  In the trachea, or windpipe, there are tracheal rings, also known as tracheal cartilages. Cartilage is strong but flexible tissue. The tracheal cartilages help support  supports the arytenoid cartilages which play a critical role in vocal function (2). The most inferior portion of the trachea, the bifurcation, is called the carina.

located specifically on the ventrolateral surface of the medulla; monitor pH changes of CSF. peripheral chemoreceptors. housed within walls of specific blood vessels; stimulated by blood pH or changes in blood respiratory gases and results in either an increase or decrease of breathing rate and depth. carotid bodies. The cough reflex has both sensory mainly via the vagus nerve and motor components. Pulmonary irritant receptors in the epithelium of the respiratory tract are sensitive to both mechanical and chemical stimuli. The bronchi and trachea are so sensitive to light touch that slight amounts of foreign matter or other causes of irritation initiate the cough reflex. The larynx and carina are especially sensitive.

Larynx anatomy Another function of the mucus is to trap inhaled particles such as dust or bacteria and prevent their entrance into the lower part of respiratory tract. The particles which are trapped by the mucus are transported via the larynx and the pharynx, swallowed and eliminated into the stomach. The mucous membrane of the carina is the most sensitive area of the trachea and larynx for triggering a cough reflex. Widening and distortion of the carina is a serious sign because it usually indicates carcinoma of the lymph nodes around the region where the trachea divides.
