fibrous column The answer you are looking for is: renal column
The renal pyramids are located in the cortex of the kidney.
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.
The cortex of the kidney is the outer layer containing medullary rays (striations formed by tubules) and medullary lobules (cortical tissue). This region also contains the main filtration mechanisms: renal (Malphighian) corpuscles that contain glomeruli (capillary tufts). The red/brown color is due to the blood within the many capillaries of this area.
A high osmotic gradient between the cortex and the medulla is caused by the running, walking, or jumping of a human person. These simple actions cause the osmotic gradient to rise significantly.
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.
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.
the cortical nephron is another type of nephron which has shorter loop of henle extended in medulla region. it has no proper function but it works like as ultra filtration etc as juxta medullary nephron perform but juxta medullary has proper function.
Renal pyramids (or malpighian pyramids) are cone-shaped tissues of the kidney. The renal medulla is made up of 7 to 18 of these conical subdivisions (usually 7 in humans). The broad base of each pyramid faces the renal cortex, and its apex, or papilla, points internally. The pyramids appear striped because they are formed by straight parallel segments of nephrons.
