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 ridge in the upper part of the picture is the high pressure of the upper esophageal sphincter which only opens for a short time to let water pass. Peristalsis is a radially symmetrical contraction and relaxation of muscles that propagates in a wave down a tube, in an anterograde direction.eristaltic movement comprises relaxation of circular smooth muscles, then their contraction behind the chewed material to keep it from moving backward, then longitudinal contraction to push it forward. Earthworms use a similar mechanism to drive their locomotion, and some modern machinery imitates this design.
