It is thought that the processes underlying pain perception involve primarily the thalamus and cortex. In this chapter we review the anatomy and physiology of pain pathways. We also discuss some of the physiological processes that modify the pain experience and that may contribute to the development of chronicity.
The anatomy and physiology of pain - ScienceDirect
2016年2月1日 · This article gives a broad overview of the anatomy and physiology of pain. It explains pain as a complex experience involving both physical and psychological adaptations. The normal pain pathways are described in some detail in a systematic fashion from nociceptor to central nervous system and back to periphery.

2023年7月24日 · Nociceptive signal transduction to the brain is what elicits the perception of pain. The complex biopsychosocial phenomenon of pain occurs in the cortical and subcortical regions, such as the thalamus, amygdala, hypothalamus, periaqueductal grey, basal ganglia and areas of the cerebral cortex.
While there is no hard-wired pain circuitry, there are physio-logically specialized peripheral sensory neurons that respond to noxious stimuli, namely nociceptors. These are free, unen-capsulated peripheral nerve endings found in most tissues of the.
Physiology, Anatomy, and Pharmacology of Pain Perception
Our current understanding of pain perception is a synthesis of neurophysiology, neuropharmacology, and neuroanatomy. Neurophysiologic concepts developed in the late 19th century and refined over the last 20 years have provided a strong conceptual framework through...
Nociception is the neural process involving the transduction and transmission of a noxious stim-ulus to the brain via a pain pathway. Pain is the result of a complex interplay between signalling systems, modulation from higher centres and the unique perception of the individual. We learn about pain when we experience injury in early life.

2017年3月1日 · This chapter focuses on pain anatomy and physiology to provide a comprehensive review of the mechanisms of nociception for preparation for the ABA Pain Medicine (PM) Examination. It reviews the anatomy of pain pathways (particularly the spinothalamic sensory tract), and the process of pain conduction from peripheral nociceptors to …
Pain is a complex perceptual experience. The transmission of pain in-volves both peripheral and central processes that can be modulated at many levels. Peripheral sensitization causes increased afferent input to the spinal cord. Numerous receptors and ion channels are involved.
