The ventral layer of arachnoid membrane, on the other hand, is a direct anterior extension of this arachnoid envelope that the dorsal layer forms over the pineal region. [4] [clarification needed] The arachnoid mater in the rat is composed of approximately 10 layers of fibroblast cells. [5]
The renal fascia separates the adipose capsule of kidney from the overlying pararenal fat. The deeper layers deep to the renal fascia are, in order, the adipose capsule (or perirenal fat), the renal capsule and finally the parenchyma of the renal cortex. [2] At the renal hilum, the renal capsule extends into the renal sinus. [1]
Arachnoiditis is an inflammatory condition of the arachnoid mater or 'arachnoid', one of the membranes known as meninges that surround and protect the central nervous system. The outermost layer of the meninges is the dura mater (Latin for hard) and adheres to inner surface of the skull and vertebrae. [ 1 ]
AKI - the other main type of kidney disease - can be caused by dehydration, blood loss, urinary tract obstructions such as kidney stones or blood clots, low blood pressure, or heart disease. It ...
The outer layer of each kidney is made up of a fibrous sheath called a renal capsule. The peripheral layer of the kidney is called the cortex, and the inner layer is called the medulla. The medulla consists of pyramids (also called malpighian pyramids), ascending with their base to the cortex and forming together with it the renal lobe. [59]
This thin, transparent membrane is composed of fibrous tissue and, like the pia mater, has an outer layer of tightly packed flat cells, forming the arachnoid barrier. [8] The shape of the arachnoid does not follow the convolutions of the surface of the brain and so looks like a loosely fitting sac. In particular, in the region of the brain a ...
The glomerular basement membrane of the kidney is the basal lamina layer of the glomerulus.The glomerular endothelial cells, the glomerular basement membrane, and the filtration slits between the podocytes perform the filtration function of the glomerulus, separating the blood in the capillaries from the filtrate that forms in Bowman's capsule. [1]
This filtrate then flows along the length of the nephron, which is a tubular structure lined by a single layer of specialized cells and surrounded by capillaries. The major functions of these lining cells are the reabsorption of water and small molecules from the filtrate into the blood, and the secretion of wastes from the blood into the urine.
