Demodicosis, also called red mange or demodex, is a skin disease caused by Demodex canis, a cigar-shaped microscopic mite that is a normal inhabitant of canine skin and found on most healthy dogs. The mite infests hair follicles and occasionally the sebaceous glands of the skin.ange is a generic term that describes a hair loss and skin condition caused by microscopic parasite s, called mites that live on or in the skin.
A crista (/ËkrÉªstÉ/ , pl. cristae cristÃ¦ and) cristae is a fold in the inner membrane of a. mitochondrionristae are studded with proteins, including ATP synthase and a variety of cytochromes. With the discovery of the dual membrane nature of mitochondria, the pioneers of mitochondrial ultrastructural research proposed different models for the organization of the mitochondrial inner membrane.
The function of cristae is to expand the surface area of the mitochondria. The cristae are the inner foldings of membrane within the mitochondria. On the cristae, there are â¦ sites where cellular respiration occurs. Cellular respiration breaks down sugars into energy to be used in the cell. So, conclusively, the cristae expand the surface area for cellular respiration sites to occur, thus allowing a greater net amount of energy for the cell to use.
