[Spatial organization and interrelations of the structural elements in the human hair follicle]
Abstract:
A complex morphological investigation of the human hair follicle and root has been performed by means of scanning electron microscopy. A volumetric image on all structural elements in the hair follicle and on their spacial interrelations both with each other and with neighbouring tissues have been obtained. A connection of the hair root cuticle and the internal root shealth cuticle by means of variously directed position of their cell-squamae is demonstrated. Between the granule-containing and the pale layers of the inner root sheath (Huxley's and Henle's layers) there is an additional connection, that is mediated at the expense of entrance of pterygoid processes of cells of the granule-containing layer into the oval spaces between the cells of the pale epithelial layer. The connective tissue hair bursa consists of layer-cases inserting into each other, constructed mainly of flat collagenous fibers and connected with each other by connective fibers.
