A mycorrhiza (Greek: Î¼ÏÎºÏÏ, mykÃ³s, fungus, and ÏÎ¯Î¶Î±, riza, root, pl. mycorrhizae or mycorrhizas) is a symbiotic association between a fungus and the roots of a vascular host plant. The term mycorrhiza refers to the role of the fungi in the plants' rhizosphere, its root system. Mycorrhizae play important roles in soil biology and soil chemistry.
The dermis consists of a papillary and a reticular layer which serve to protect and cushion the body from stress and strain. Differentiate among the regions of the dermis and the hypodermis. The dermis is divided into a papillary region and a reticular region.
This layer is home to many minor skin imperfections like fine wrinkle lines and blemishes. All of the action in microdermabrasion takes place at the level of the stratum corneum. Since it only really targets the epidermis (and not the dermis), it is more accurate to call it micro-epi-dermabrasion.
