Striae atrophicans are a cutaneous condition characterized by usually multiple, symmetric, well-defined linear atrophic lesions that often follow the lines of ...
Striae are caused by tearing of the dermis during periods of rapid growth of the body, such as during puberty or pregnancy, in which they usually form during the last trimester. Usually on the belly, these striae also commonly occur on the breasts, thighs, hips, lower back, and buttocks. Pregnancy-related striae are known as striae gravidarum. [2]
Glacial striations or striae are scratches or gouges cut into bedrock by glacial abrasion. These scratches and gouges were first recognized as the result of a moving glacier in the late 18th century when Swiss alpinists first associated them with moving glaciers. They also noted that if they were visible today that the glaciers must also be ...
The ciliary rootlet is a cytoskeleton-like structure that originates from the basal body at the proximal end of a cilium. Rootlets are typically 80-100 nm in diameter and contain cross striae distributed at regular intervals of approximately 55-70 nm.

Morphology of a male skeleton shrimp, Caprella mutica Morphology in biology is the study of the form and structure of organisms and their specific structural features. [1]This includes aspects of the outward appearance (shape, structure, color, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of internal parts like bones and organs, i.e. internal ...
Occasional darker striae or grooves of Retzius result from systemic disturbances in the human body. For example, a fever can cause some lines to appear darker than those surrounding them. Normally, amelogenesis involves a period of enamel matrix formation and a rest period.
Haab's striae, or Descemet's tears, are horizontal breaks in the Descemet membrane [1] associated with congenital glaucoma. [2] It is named after Otto Haab. These occur because descemet's membrane is less elastic than the corneal stroma. Tears are usually peripheral, concentric with limbus and appear as line with double contour.
