Figures 109 and 110.
The brain issues the instruction to divide to those
cells whose division is desired. With the transmission
of that command to the relevant cells, the appropriate
hormones are secreted. When the hormone comes to
the cell, it notifies the receptor-protein on the cell
membrane. The message received by the protein is re-
ported to the center, whereupon the cell understands
this message, makes a decision and acts accordingly.
