Centrioles are arguably the most enigmatic cell organelles. In most animal
cells, a pair of centrioles resides in the centrosome — a macromolecular
complex that organizes the microtubule system (part of the cell's internal
skeleton). The two centrioles, a mother and a daughter, "are positioned at
right angles to each other". This quote from a popular textbook epitomizes the
idea of a fixed arrangement of the two bodies within the centrosome (see part a
in the figure: at the top is an end-on view of one of the centrioles, while at
the bottom is a longitudinal view of the other centriole). Deviations from a
close apposition are considered exceptional.
