[Functional state of the hypothalamo-hypophyseo-adrenal system of guinea pigs under the influence of angular
Abstract:
Experiments were conducted on guinea pigs. A study was made of the influence of increased gravitation on the activity of the hypothalamo-hypophysio-adrenal system. It appeared that a single centrifugation led to the activation of the mentioned system; however, repeated action of the angular accelerations on the animal organism failed to lead to any increase in the blood corticosteroid level (on the 6th-11th days); this can be attributed to the adaptation of the central link of the hypophysio-adrenal system to the given stimulus, and not to the exhaustion of the adrenal cortex.

Sympathetic Pathways: Collateral Ganglia and Adrenal Medulla
Collateral Ganglia
Sympathetic preganglionic axons reach the collateral ganglia along the route of splanchnic nerves. These nerves bypass the sympathetic trunk and communicate with sympathetic postganglionic neurons housed in the prevertebral ganglia. These ganglia supply the organs of the abdominopelvic cavity.

Hormones of the Adrenal Glands
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and...
