Epithelium; Cell Types:

figure Two types of epithelial cells are found within the urinary space of Bowman’s capsule. The first of these are the parietal epithelial cells that line the inside of Bowman’s capsule. These cells are not part of the filtration barrier. The second type of epithelial cells are the visceral epithelial cells or podocytes, which rest on the basement membrane of the glomerular capillary and which are the largest of the cells in the glomerulus. Extending from the main cell body of the podocytes are primary processes from which pedicels or foot processes extend and actually contact the lamina rara externa of the basement membrane. Additional pedicels also arise from secondary and tertiary processes.
