Trachealis muscle The trachealis muscle is a smooth muscle that bridges the gap between the free ends of C-shaped cartilages at the posterior border of the trachea, adjacent to the esophagus. The primary function of the trachealis muscle is to constrict the trachea, allowing air to be expelled with more force e.g. during coughing.

- The trachea, commonly known as the windpipe, is a tube about 4 inches long and less than an inch in diameter in most people. The trachea begins just under the larynx (voice box) and runs down behind the breastbone (sternum). The trachea then divides into two smaller tubes called bronchi: one bronchus for each lung. The trachea is composed of about 20 rings of tough cartilage. The back part of each ring is made of muscle and connective tissue. Moist, smooth tissue called mucosa lines the inside of the trachea.

trachea the air passage extending from the larynx to the main bronchi; called also the windpipe. This tube is reinforced by a series of C-shaped rings of cartilage that keep the passage uniformly open. The gaps between the rings are bridged by strong fibroelastic membranes.

Speech Single cartilages are the shield-shaped thyroid in front, whose prominence forms the “Adam’s apple” in the male; the cricoid cartilage below, which resembles a signet ring and connects the thyroid to the trachea or windpipe; and the leaf-shaped epiglottis, or laryngeal lid, on top. Among the paired cartilages are...

Trachea (Windpipe) 1 Longitudinal smooth muscle fibers are present in the posterior trachea between the ends of the cartilage rings. 2  This smooth muscle tissue allows the trachea to adjust its diameter as needed. 3  Surrounding the submucosa is a layer of hyaline cartilage that forms the supportive rings of the trachea.lick to read more below. The trachea (or windpipe) is a wide, hollow tube that connects the larynx (or voice box) to the bronchi of the lungs. It is an integral part of the body’s airway and has the vital function of providing air flow to and from the lungs for respiration.

- It is a bit like an archers bow in that when the muscle contracts the two end of the C are brought closer together, giving a more circular shape and reducing the size of the airway. when the muscle relaces the tension in the cartilage opens the airway again.

Trachea The cricoid cartilage is the only complete ring of cartilage in the trachea. Below this there are from fifteen to twenty incomplete C-shaped tracheal rings of cartilage that reinforce the front and sides of the trachea to protect and maintain the airway.he epiglottis closes the opening to the larynx during swallowing. The trachea develops in the second month of development. It is lined with an epithelium that has goblet cells which produce protective mucins. An inflammatory condition, also involving the larynx and bronchi, called croup can result in a barking cough.

Epithelial Tissue function:- The ciliated epithelium cleans out the particulate material in the air before it enters the lungs.

Top 30 Doctor insights on: What Is The Purpose Of The Cartilage Rings Of Trachea And Bronchi Get help from a doctor now ›. Support: The cartilage rings (which aren't really rings because they don't go all the way around) give support to the trachea so it doesn't collapse during respiration and give some protection as well.ronchi (Definition). Bronchi is also known as Bronchus. Bronchi are the major passageways through which air passes in and out of the lung. The bronchi divide into smaller passageways to distribute air throughout the lung. It is like a system of tubes that divide and spread out through the lungs.

Explain why the cartilage rings in the trachea are C-shaped? Answer by Silvia Ventura. Confidence votes 105. The cartilage rings in the trachea need to be C shaped so large masses of food can pass through the esophagus during swallowing and large masses of air can pass through the trachea.he 'c' shaped cartilage rings are present in the trachea to prevent it from collapsing and they keep the trachea open for air to come in and out.

This cartilage consists of strong connective tissue constituting the dorsal (back) part of the larynx, or voice box.The cricoid cartilage is located slightly below the thyroid cartilage, which it connects with through the medial cricothyroid ligament.It also joins the first tracheal ring through the cricotracheal ligament.
