The affected individuals experienced hair loss as they spent greater amounts of time targeting affected areas while grooming. [12] A parasite-induced dermatological disease named sarcoptic mange occurs in dogs infected with mites ( Sarcoptes scabiei var canis ) and alopecia is often among the main symptoms experienced by the affected ...
These genes encode proteins important for hair shaft formation. [8] Clinical symptoms of the disorder arise between 3 months and 12 years of age. The quantity of hair on the head does not change, but hair starts to grow more slowly and becomes increasingly "uncombable". To be clinically apparent, 50% of all scalp hair shafts must be affected by ...
A true endoskeleton is derived from mesodermal tissue. In three phyla of animals, Chordata, Echinodermata and Porifera (), endoskeletons of various complexity are found.An endoskeleton may function purely for structural support (as in the case of Porifera), but often also serves as an attachment site for muscles and a mechanism for transmitting muscular forces as in chordates and echinoderms ...

[1] It commonly results from a person frequently wearing their hair in a particularly tight ponytail, pigtails, or braids with increased likelihood when hair is chemically relaxed as this compromises the hair shaft's tensile strength resulting in hair breakage.
Trichorrhexis nodosa is a defect in the hair shaft characterized by thickening or weak points (nodes) that cause the hair to break off easily. [ 2 ] [ 3 ] : 636 This group of conditions contributes to the appearance of hair loss , lack of growth, and damaged-looking hair.
