Summary
Gonad function is depressed and thryoid function activated in male pigeons under conditions of intensive growth of feathers. At the same time the discharge of neurosecretion into the blood from the posterior lobe of the hypophysis becomes stimulated and the entrance of a new secretion into the area of the median eminence of the neurohypophysis is intensified.
Increased vascularization and hyperemia are seen in the anterior lobe of the hypophysis; in such conditions the formation of new typical basophils is enhanced. A reciprocal relationship between the thyroid gland function and the concentration of its hormone in the organism is realized through the activation of the neurosecretory and thyrotropic functions.
