The columns in this structure that radiate outward from the striated conical masses are named the pars radiata or the processes of Ferrein.
The columns in this structure that radiate outward from the striated conical masses are named the pars radiata or the processes of Ferrein. The medulla of it consists of eight to eighteen Malphighian pyramids, which contain excretory ducts that empty into a minor calyx. Its primary functional unit begins as a double walled, cup-shaped expansion enclosing a tuft of capillaries known as the glomerulus. This expansion, Bowman's capsule, becomes a tortuous, confoluted mass called nephrons. For ten points, name these organs that separates urea and other nitrogenous waste products from the blood.
