Hyaline

Hyaline describes something that is transparent or translucent, resembling clear glass or crystal. It refers to a material or substance that allows light to pass through with minimal scattering, resulting in a clear or faintly colored appearance. The term is often used in biology and medicine to describe tissues, cells, or substances that have a glassy, clear, or semitransparent quality. This clarity is usually due to the homogenous nature of the material, with light passing through unobstructed. The etymology of the word derives from the Greek 'hyalos,' meaning 'glass' or 'crystal,' reflecting its defining characteristic.

Hyaline meaning with examples

• The microscopic examination of the lung tissue revealed the presence of hyaline membranes in the alveoli. These membranes, composed of proteinaceous material, were indicative of acute respiratory distress syndrome (ARDS). The clarity of the membranes, which appeared glassy under the microscope, was a key diagnostic feature in the pathologist's assessment. The hyaline nature of the membranes hindered proper gas exchange.
• During the histological analysis of the cartilage, the matrix appeared hyaline. This transparent quality allowed for easy visualization of the chondrocytes within the lacunae. The smooth, glassy appearance of the hyaline cartilage was a stark contrast to the more opaque appearance of other connective tissues. The clarity was important for observing the cells responsible for the support structure.
• A sample of the cornea, examined under a light microscope, exhibited a hyaline structure. The corneal stroma appeared as a clear, translucent layer, composed primarily of collagen fibers and ground substance. This hyaline composition is crucial for the cornea's ability to refract light and provide clear vision. Any disruption to its hyaline nature could impact the patients sight.
• The pathologist noted a hyaline change in the affected renal tubules, a sign of tubular damage. The normally clear or faintly colored cells became glassy in appearance, a result of protein accumulation. This hyaline change, visualized during the microscopic assessment, helped pinpoint the disease's stage and helped with treatment. It signified cellular dysfunction.
• The pathologist was examining the fluid aspirated from the joint cavity. The fluid showed a hyaline character. The fluid appeared clear and almost colorless, similar to a diluted glass of water. The nature of the fluid suggested the absence of inflammation or infection, aiding in the differential diagnosis and helping the clinicians to come up with a plan of action.
