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."
Pulmonary edema (British English: oedema), also known as pulmonary congestion, is excessive fluid accumulation in the tissue or air spaces (usually alveoli) of the lungs. [1] This leads to impaired gas exchange , most often leading to shortness of breath ( dyspnea ) which can progress to hypoxemia and respiratory failure .
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.
Whipple's disease is a rare systemic infectious disease caused by the bacterium Tropheryma whipplei.First described by George Hoyt Whipple in 1907 and commonly considered as a gastrointestinal disorder, Whipple's disease primarily causes malabsorption, but may affect any part of the human body, including the heart, brain, joints, skin, lungs and the eyes.

The liquid can be pulmonary edema, inflammatory exudate, pus, inhaled water, or blood (from bronchial tree or hemorrhage from a pulmonary artery). Consolidation must be present to diagnose pneumonia : the signs of lobar pneumonia are characteristic and clinically referred to as consolidation.
The differential diagnosis for ground-glass opacities is broad. General etiologies include infections, interstitial lung diseases, pulmonary edema, pulmonary hemorrhage, and neoplasm. A correlation of imaging with a patient's clinical features is useful in narrowing the diagnosis. [6] [7] GGOs can be seen in normal lungs. Upon expiration there ...
Since the basal lamina secures the epithelium to the superficial layer of the lamina propria with anchoring fibers, this is a common site for injury. If a person has a phonotrauma or habitual vocal hyperfunction, also known as pressed phonation, the proteins in the basal lamina can shear, causing vocal fold injury, usually seen as nodules or ...
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 ...
