C. Interrelationships involving the Adrenal Bodies 

 (Ghromaphil Tissues and Adrenal Cortex) 



Action of the Adrenal Bodies upon the Gonads 



An important connection between the adrenals and the 

 reproductive organs has long been recognized. The main facts 

 are given in another chapter (see Chap. XI). In this place 

 we need only remind the reader of the frequent association 

 between sex anomalies and tumours of the adrenal cortex. It 

 is stated also that vigour of reproduction is reduced by partial 

 adrenal extirpation. The theory is that the cortex -of the 

 adrenal body stimulates the growth of the reproductive organs, 

 especially in the male. 



So far as I am aware, there are no observations which point 

 to any direct connection between the adrenal medulla or other 

 chromaphil tissues and the sex organs. 



Action of the Adrenal Bodies upon the Thymus 



Hypertrophy of the thymus has been recorded in cases of 

 Addison's disease, and the association of adrenal hypoplasia 

 and thymus hypertrophy is said to be common in status lym- 

 phaticus. There is also some experimental evidence that 

 adrenal deficiency is frequently associated with hypertrophy 

 of the pancreas. 



Action of the Adrenal Bodies upon the Pituitary 

 At present there is little evidence of any relationship of the 

 adrenals to the pituitary. 



Action of the Adrenal Bodies upon the Thyroid 

 Hypertrophy of the thyroids has been reported in some cases 

 after extirpation of the adrenals, but we have not sufficient 

 data to justify any statement as to a direct action of the former 

 organ upon the latter. 



Action of the Adrenal Bodies upon the Pancreas 

 This matter has already been discussed in the chapter 



devoted to the adrenal bodies (see Chap. XL). 



Here it is only necessary to point out that the whole of the 



effect of the adrenal bodies upon carbohydrate metabolism is
