Loose connective tissue skin and mucous membranes, it is more compact and sometimes difficult to distinguish from dense irregular connective tissue. Areolar connective tissues hold organs in place and attaches epithelial tissue to other underlying tissues. It also serves as a reservoir of water and salts for surrounding tissues. Almost all cells obtain their nutrients from and release their wastes into areolar connective tissue. Organs that are rich in loose connective tissue(such as the eyelids) are usually sites that undergo oedema indicating renal failure or nephrotic syndrome. Thus periorbital swelling is one characteristic finding in severe renal disease Loose connective tissue Loose connective
Cerebral edema Cerebral edema Cerebral edema is excess accumulation of fluid (edema) in the intracellular or extracellular spaces of the brain. Most changes in morphology are associated with cerebral edema: the brain becomes soft and smooth and overfills the cranial vault, gyri become flattened, sulci become narrowed, and ventricular cavities become compressed. Symptoms include nausea, vomiting, blurred vision, faintness, and in severe cases, seizures and coma. If brain herniation occurs, respiratory symptoms or respiratory arrest can also occur due to compression of the respiratory centres in the pons and medulla oblongata. Cerebral edema can result from brain trauma or from nontraumatic causes
