Histological response of various endocrine glands after administration of certain neurohumors in chicks.

Histological response of various endocrine glands like pituitary, adrenal, testes and pancreas after administration of certain neurohumors like acetylcholine, adrenaline and histamine in a particular dose and sequence, has been carried out in white leghorn chicks. Result of this study revealed that administration of these neurohumors produced definite changes in various endocrines. Histological changes are more prominent in pituitary and adrenal glands, whereas, pancreas and testes did not reveal much influence of these neurohumors.
