Résumé
Histological investigation of the skin and hair of the adult chinchilla mammal is reported in the article. The Chinchilla is a hystricomorph rodent, native to the Andes of Bolivia, Chile and Peru; its valuable fur has led to more widespread distribution. Samples of biological tissue were fixed in Bouin's solution, embedded in paraffin, sectioned, and stained with haematoxylin and eosin for examination using the light microscope (LM). The general body hair of the chinchilla is uniformly arranged in dense clusters of up to 75 hairs. Each cluster typically consists of a single guard hair and two lateral groups of wool hairs. All the hairs of a single cluster emerge through a common pore. Each hair cluster has a single arrector pili muscle. Guard hairs have their own sebaceous glands, while three or four other glands serve all the hairs of a lateral group. Independent hairs are found only as vibrissae or on tail and pinnae. Follicular layering is found only in the vibrissae. The dense clusters of hairs in the adult chinchilla contrast with the independent hairs in the 105-day fetus. The transition from the fetal state to the adult occurs before the second month after birth.
