The lamina propria is a thin layer of loose (areolar) connective tissue, which lies beneath the epithelium, and together with the epithelium and basement membrane constitutes the mucosa. As its Latin name indicates, it is a characteristic component of the mucosa, or the mucosa's "own special layer."
Newborns have a uniform single layered lamina propria, which appears loose with no vocal ligament. [4] The monolayered lamina propria is composed of ground substances such as hyaluronic acid and fibronectin, fibroblasts, elastic fibers, and collagenous fibers. While the fibrous components are sparse, making the lamina propria structure loose ...
The cover is composed of the epithelium (mucosa), basal lamina (or basement membrane zone), and the superficial layer of the lamina propria. The transition is composed of the intermediate and deep layers of the lamina propria. The body is composed of the thyroarytenoid muscle. This layered structure of tissues is very important for vibration of ...
The lamina propria, a layer of connective tissue within the mucosa. The muscularis mucosae, a thin layer of smooth muscle. The epithelium, the most exposed part of the mucosa, is a glandular epithelium with many goblet cells. Goblet cells secrete mucus, which lubricates the passage of food along and protects the intestinal wall from digestive ...
The mucosa is composed of one or more layers of epithelial cells that secrete mucus, and an underlying lamina propria of loose connective tissue. [1] The type of cells and type of mucus secreted vary from organ to organ and each can differ along a given tract. [2] [3]
The dense layer is the deeper layer of the lamina propria. It consists of dense connective tissue with a large amount of fibers. Between the papillary layer and the deeper layers of the lamina propria is a capillary plexus, which provides nutrition for the all layers of the mucosa and sends capillaries into the connective tissue papillae. [10]
The vocal folds consist of 3 primary layers; the Epithelium, the Lamina Propria (containing superficial, intermediate and deep layers) and the Thyroarytenoid Muscle. Vocal fold cysts commonly appear in the Superficial portion of the Lamina Propria, the cyst size impacts the nature of this layer making it more rigid.
The Reinke's space is sometimes referred to as the superficial lamina propria. [5] Reinke's edema is characterized by the "sac-like" appearance of the fluid-filled vocal cords. [6] The swelling of the vocal folds causes the voice to become deep and hoarse. Therefore, the major symptom of Reinke's edema is a hoarseness similar to laryngitis.
