A whorl is a ring of cells or tissue that surrounds and wraps itself around another in a circular pattern. Whorls can be found at the ends or in the middle of various structures. Some organ structures are described as whorls and utilised to aid in identification.
A whorl-shaped structure is the Hassall’s corpuscle, which is made up of type VI epithelial reticular cells in the thymus.
Whorl
A whorl is a collection of leaves, sepals, petals, stamens or carpels that radiate from a central point and wrap around the stem or stalk. A leaf whorl consists of at least three sections; it does not consist of two opposing leaves.
Except in plant species with very short internodes and some other genera, it is uncommon for leaves to grow in whorls (Galium, Nerium, Elodea etc.). Some trees, such as Brabejum stellatifolium and other Proteaceae species, have leaf whorls (e.g., in the genus Banksia). Internodes within the leaf whorls alternate with long internodes between the whorls in plants like these.
Whorl Explanation
Whorl (mollusc): In the spiral growth of a mollusk shell, a whorl is a single, complete 360° revolution or turn. Shells with a spiral configuration can be found in a variety of gastropods, as well as shelled cephalopods including Nautilus, Spirula, and the ammonites, a major extinct subclass of cephalopods.
For reasons of both strength and compactness, a spiral shell can be imagined as a long conical tube whose growth is coiled into an overall helical or planispiral shape.
As per D’Arcy Wentworth Thompson’s classic 1917 book On Growth and Form, and David Raup, the number of whorls in an adult shell of a specific species is determined by mathematical elements in geometric growth. The rate at which the conical tube expands (or flares out) over time is the most important element. The adult shell has several whorls when the rate of expansion is low, and each consecutive whorl is not significantly wider than the previous one. When the mathematical variables determining the pattern of growth cause the conical shape of the shell tube to expand very quickly, the adult shell contains very few whorls.
Hair Whorl: A hair whorl is a circular patch of hair that grows around a visible centre point. Hair whorls can be found on the body as well as the head of most hairy animals. The direction of growth of hair whorls, also known as crowns, swirls, or trichoglyphs, can be either clockwise or counterclockwise.
Spindle Whorl: A spindle whorl is a disc or spherical item that is attached to the spindle in order to improve and sustain spin speed. Amber, antler, bone, porcelain, coral, glass, stone, metal (iron, lead, lead alloy), and wood have all been used to make whorls in the past (oak). Locally sourced materials such as chalk, limestone, mudstone, sandstone, slate, lydite, and soapstone were also utilised.
Nape Whorl Meaning
A hair whorl is a hair development pattern in which a segment of hair develops in a spiral or curved pattern. This is frequently obvious because the hair emerges from the skin at a shallow angle, reinforcing the whorl’s direction.
Some whorls might be intriguing hair features depending on their placement (Half-whorls at the front hairline, for example, generate unique curves in the bangs). They do, however, provide a challenge that must be addressed in the majority of cases.
The key to dealing with whorls and other growth patterns is to choose styles that either include the whorl’s influence or seek to overcome or disguise it. If you prefer short hairstyles with tapering necklines, keep the hair around the nape of the neck short enough to style near to the scalp.
