Block1/Fig 1. Epithelia in the renal cortex.

block1_08.jpg - Fig 1. Epithelia in the renal cortex. This micrograph reveals asectioned renal corpuscle and adjacent renal tubules. Therenal corpuscle consists of a special cpillary bed, theglomerulus, and the Bowman's capsule. The paietal layer ofBowman's capsule (pBC) composed of simple squamousepithelium. The epithelial cells are very flat, as judged by theshape of their nuclei. Note that cell boundary are not evidentand the nuclei are unevenly. The uneven spacing is becausethe sectioning knife passes through some cells withoutincluding the nucleus. The cross-sectioned (cs), marked withasterisks (*), and longitudinal-sectioned (ls), marked with arrow(¡÷), of renal tubules provide good examples of a simplecuboidal epithelium; note that cell width approximates cellheight. Although the boundaries between individual cells aredistinct, the nuclear shape provides an approximate indicationof the cell size and shape.

The uneven spacing is because the sectioning knife passes through some cells without including the nucleus. The cross-sectioned (cs), marked with asterisks (*), and longitudinal-sectioned (ls), marked with arrow (→), of renal tubules provide good examples of a simple cuboidal epithelium; note that cell width approximates cell height. Although the boundaries between individual cells are distinct, the nuclear shape provides an approximate indication of the cell size and shape.
