The term hyaline
(from the Greek ὕαλος
‘glassy’) literally refers to a substance with a glass-like appearance.
In common medical histopathological usage, hyaline is a substance with a glassy, pink appearance after haematoxylin and eosin staining—most often an acellular, proteinaceous material. Hyaline cartilage is the clear, shiny ("glass-like") cartilage of articular joints.
In other scientific fields such as ichthyology and entomology, hyaline may refer to a specific type of colorless and transparent substance.
