Specialized ganglionic sympathetic neurons that release hormones into the bloodstream are found within the collateral ganglia. a
alex41 [277]

Specialized ganglionic sympathetic neurons that release hormones into the bloodstream are found within the adrenal glands.

<h3>What is adrenal gland?</h3>
  • A little gland that produces noradrenaline, adrenaline, and steroid hormones.
  • These hormones assist in maintaining healthy blood pressure, heart rate, and other vital bodily functions.
  • Immune system, blood pressure, stress response, metabolism, and other critical processes are all controlled by hormones that are produced by adrenal glands.
  • The cortex and the medulla, the two components that make up an adrenal gland, are each in charge of manufacturing a separate hormone.
  • Problems with one, both, or other glands, such as the pituitary gland, can result in diseases of the adrenal glands.
  • When the adrenal glands create either an excessive amount of hormones or an excessive amount of hormones from external sources, several diseases may arise.
  • Since the adrenal glands are essential for human survival, if both are destroyed, the patient will need to take drugs and hormone supplements.
