One point,however, should be emphasized and that is that the activities of theinternal secretion organs are all under vegetative nervous systemcontrol. The active substances, hormones, if one wishes, are not. Fig. 62. -To show the probable mode of action of certain of the internal secretions uponthe spinal reflex arc.

The output of iodine, ofcalcium, of adrenalin, of hypophysin and of all of the substancesthus far known or named is controlled almost exclusively by thenervous system. The internal secretions act through the nervoussystem. While it may be shown that within an organ itself primary
