Endocrine Glands
Regulation of Endocrine Glands

Endocrine glands and the Hormones they secrete are closely linked with The Nervous system, forming a unified integrative regulatory mechanism. The regulatory Influence of the Central Nervous System on the physiological activity of endocrine glands is mediated by the Hypothalamus. In turn, the hypothalamus is connected via afferent pathways with other PARTS OF THE central nervous system (including the Spinal Cord, Medulla Oblongata, Midbrain, thalamus, Basal Ganglia, and Cerebral Cortex). These connections allow the hypothalamus to receive information from all parts of the body: signals from extero- and interoceptors travel to the central nervous system through the hypothalamus and are transmitted to the endocrine Organs.

Thus, neurosecretory Cells of the hypothalamus convert afferent stimuli into physiologically active humoral factors (releasing hormones, or liberins), which stimulate the synthesis and release of Pituitary Hormones. Hormones that inhibit these processes are termed inhibiting hormones (or factors) or statins.

Hypothalamic releasing hormones affect the function of pituitary cells, which produce a range of hormones. These, in turn, regulate the Synthesis and Secretion of hormones from peripheral endocrine glands, which then act upon target organs or Tissues. All levels of this interactive system are closely interconnected via feedback loops. Furthermore, various hormones are known to influence the Functions of different Regions of the central nervous system as well.

An important role in The regulation of endocrine gland function is played by Neurotransmitters of the sympathetic and parasympathetic nerve fibers.

However, certain endocrine glands (such as the parathyroid and Pancreas) are regulated through alternative pathways—namely, via METABOLISM/18.html">The Influence of antagonist hormone levels and Changes in the concentration of the metabolites (substances) whose levels these hormones control. Additionally, some hormones produced in the hypothalamus (antidiuretic hormone, oxytocin) and pituitary hormones act directly on target organs and tissues.

Thus, the regulation of endocrine glands in The Human Body represents a complex system involving many yet-to-be-fully-understood processes.
