The dermis is tightly connected to the epidermis through a basement membrane. Structural components of the dermis are collagen, elastic fibers, and extrafibrillar matrix. It also contains Mechanoreceptors that provide the sense of touch and thermoreceptors that provide the sense of heat.part from these cells, the dermis is also composed of matrix components such as collagen (which provides strength), elastin (which provides elasticity), and extrafibrillar matrix, an extracellular gel-like substance primarily composed of glycosaminoglycans (most notably hyaluronan), proteoglycans, and glycoproteins.
Ischemia is a condition in which the blood flow (and thus oxygen) is restricted or reduced in a part of the body. Cardiac ischemia is the name for decreased blood flow and oxygen to the heart muscle. What is ischemic heart disease? It's the term given to heart problems caused by narrowed heart arteries.
Ischemic stroke accounts for about 87 percent of all cases. View a detailed animation of ischemic stroke. Ischemic strokes occur as a result of an obstruction within a blood vessel supplying blood to the brain.The underlying condition for this type of obstruction is the development of fatty deposits lining the vessel walls.This condition is called atherosclerosis. These fatty deposits can cause two types of obstruction:schemic stroke accounts for about 87 percent of all cases. View a detailed animation of ischemic stroke.
