What Is Psychoneuroendocrinology?
Neuroendocrinology is an endocrine gland that is closely related to a specific nervous system, regardless of its genesis and function. This type of complex system depends on the two that depend on the nervous system.

- Neuroendocrinology is an endocrine gland that is closely related to a specific nervous system, regardless of its genesis and function. This type of complex system depends on the two that depend on the nervous system.
- Both endogenous and functional, endocrine glands that are closely related to a specific nervous system and are active. This type of complex system that focuses on the two dependent on the nervous system is called a neuroendocrine system. For example, the relationship between the sympathetic nervous system and adrenal medulla of vertebrates, the relationship between the hypothalamus of the mesencephalon and the pituitary gland is considered as a complex of the nervous system and endocrine system-neuroendocrine system; The subject that studies this is called neuroendocrinology.
- Basic overview
- The classic concept of the endocrine system refers to the endocrine gland composed of a group of specialized cells. They include the pituitary, thyroid, parathyroid, adrenal, gonadal, islet, thymus, and pineal gland. These glands secrete high-efficiency organic chemicals (hormones) and pass chemical information to their target cells, target tissues, or target organs through the blood circulation, exerting an exciting or inhibiting effect. Hormones are also called endocrine messengers. With the progress of endocrinology research, new understanding of the endocrine system has emerged. In addition to the above-mentioned endocrine glands, scattered endocrine tissues or cells with endocrine functions are distributed in other parts of the body, such as the gastrointestinal mucosa, brain, kidney, heart, and lungs. These scattered endocrine tissues also belong to or Included in the endocrine system. In addition, there is a new understanding of the concept of endocrine or hormones. Classical hormone refers to hormones secreted from endocrine cells to be transported to long-distance target cells (distance secretion) through the blood circulation. It is now believed that some chemicals secreted by endocrine cells can diffuse to the neighboring cells through the intercellular space. This type of chemical is called a local hormone and is secreted in close proximity.
- In terms of physiological functions, the endocrine system and the central nervous system are closely linked, cooperate closely, and interact to regulate various functions of the body and maintain a relatively stable internal environment to adapt to various changes and needs of the internal and external environment of the body. In addition, the endocrine system accepts the central nervous system's regulation indirectly or directly, and the endocrine system can also be regarded as a link of the central nervous system. The internal glandular system also affects the activity of the central nervous system. Therefore, there is now a discipline that specializes in studying the functional connection between the central nervous system and the endocrine system, called neuroendocrinology.
