- Trachea - an overview | ScienceDirect Topics
The trachea is a tube made up of cartilage, connective tissue, smooth muscle, and a mucosal layer connecting the larynx to the principal bronchi and finally to the lungs
- Tracheal Cartilages - Structure, Function Location
Tracheal cartilages are a series of C-shaped hyaline cartilage rings embedded in the wall of the trachea These rings provide structural support to keep the tracheal airway open during breathing
- Tracheal Ring Formation - PMC
Myocardin, a master regulatory of smooth muscle differentiation, is necessary for the dorsal expansion of the nascent cartilage rings to their characteristic C-shape
- Trachea | Respiratory System - Histology Guide
Histology of the trachea - respiratory epithelium, lamina propria, tracheal cartilage, trachealis muscle, and adventitia
- Respiratory: The Histology Guide
The trachea is a wide flexible tube, the lumen of which is kept open by 20 tracheal cartilages, which are C-shaped rings of hyaline cartilage The gaps between the rings of cartilage are filled by the trachealis muscle - a bundle of smooth muscle, and fibroelastic tissue

An intrapulmonary bronchus with several separate pieces of hyaline cartilage in its wall A thin layer of bright pink smooth muscle lies between the cartilage and the mucosa
- Understanding the Trachea: Anatomical Structure and Microscopic View . . .
Smooth muscle: Smooth muscle connects the open ends of the C-shaped cartilage rings, allowing the trachea to adjust its diameter during breathing This muscle also aids in expelling mucus through coughing
- Duke Histology - Respiratory System
This transverse section demonstrates the C-shaped cartilage rings of the trachea, smooth muscle along the posterior (open) portion of the cartilage, and abundant seromucous glands
- The Tracheal Wall: Its Layers, Structure, and Function
The open, C-shaped design of the cartilage rings allows the trachea to flatten slightly posteriorly, accommodating the expansion of the esophagus during swallowing The trachealis muscle, a sheet of smooth muscle, bridges the open ends of these C-rings at the back of the trachea
- OpenStax AnatPhys fig. 22. 9 - The Trachea - English labels
Trachea (a) The tracheal tube is formed by stacked, C-shaped pieces of hyaline cartilage (b) The layer visible in this cross-section of tracheal wall tissue between the hyaline cartilage and the lumen of the trachea is the mucosa, which is composed of pseudostratified ciliated columnar epithelium that contains goblet cells LM × 1220
