Nervous System

In the realm of biomedicine, the nervous system is delineated into two principal subdivisions: the Central Nervous System (CNS), encompassing the brain and spinal cord, and the Peripheral Nervous System (PNS), which consists of nerves emanating from the spinal column. These systems are inextricably linked with neuroendocrine pathways, notably the Hypothalamic-Pituitary-Adrenal (HPA) Axis, a critical feedback loop implicated in homeostasis and the modulation of chronic stress (Endocrine Reviews). Additionally, the Sympatho-Adrenal System (SAS) orchestrates the acute stress response by integrating the sympathetic nervous system with the adrenal medulla (Journal of Neuroendocrinology). In contrast, Traditional Chinese Medicine (TCM) introduces the concept of 'Shen,' a composite of cognitive and emotional faculties. TCM attributes the residence of Shen to the heart and its circulatory network (Journal of Traditional Chinese Medicine). These variegated viewpoints contribute to a nuanced understanding of nervous system functionality.
