The cortical tissues located between the pyramids are the renal cortex and renal columns. The renal cortex contains the glomeruli and convoluted tubules involved in the initial stages of urine formation, while the renal columns are extensions of the cortex that separate the renal pyramids.
renal columns
The renal pyramids are located in the cortex of the kidney.
The striped appearance of the renal pyramids is due to the arrangement of tubules and blood vessels within them. The striped effect is created by columns called medullary rays that extend from the cortex into the pyramids, containing straight tubules. These structures help in the filtration and concentration of urine in the kidneys.
the medulla is organized into a GROUP of pyramids. It makes up the pyramids.
Corticomedullary differentiation on medical diagnostic imaging is the visualisation of the difference of intensity (MRI) , echogenity (Ultrasound) or attenuation (CT) between the cortical and medullary tissue in an organ. For Example; The kidney has a cortex (the peripheral tissue) and a medulla (central to the cortex). On an ultrasound scan, the cortex should look whiter (more echogenic) than the medulla and thus, you should be able see and differentiate between these two different tissues judging by their color.. Loss of corticomedullary differentiation is what its called when both cortex and medulla are seen as the same shade of grey and one can not see any change of color (any change in shade of grey tones as most diagnostic images are black and white) on the border of cortex and medulla.
Renal columns are bands of granular tissue that separate adjacent renal pyramids. They contain vessels and urinary tubes that run to the cortex.
Kidney contain two major anatomical areas which are distinct in appearane and function,cortex(outer) and medulla(inner).Their junctional area is cortico-medullary junction.
Renal pyramids are part of the renal medulla, while renal columns are extensions of the renal cortex that separate the renal pyramids. Together, they form the internal structure of the kidney.
The cortex of the kidney is the outer region where blood is filtered to form urine, while the medulla is the inner region responsible for regulating urine concentration and reabsorption. The cortex contains the glomeruli and Bowman's capsules, whereas the medulla consists of renal tubules that help concentrate urine and carry it towards the renal pelvis for excretion.
The part of the brain known as the motor cortex controls all voluntary movements, including running.
Babolat Aeropro Drive Cortex is the one the pros like Nadal use, whereas the one without cortex is not, and therefore cheaper.
