Ciliated Renal Cell (a)

Low power micrograph showing the general ultrastructural features of the 
ciliated cell of the renal epithelium.  The cell has a well developed 
microvillus border and has numerous peripheral cilia which are attached 
into the apical cytoplasm by basal bodies and ciliary rootlets.  The apical
cytoplasm is vesiculated whilst in the mid and basal regions of the cell 
there are numerous membrane delineated vacuoles containing electron dense 
material.  The nucleus is prominent and lies in the mid region of the cell.
