   Jul 24, 2018 · The pathway that goes upward carrying sensory information from the body via the spinal cord towards the brain is defined as the ascending pathway, whereas the nerves that goes downward from the brain to the reflex organs via the spinal cord is known as the descending pathway. Pain is a vast subject and affects so many regions of an individual ...

   Sep 10, 2023 · Pain is a somatic and emotional sensation which is associated with actual or potential tissue damage. Pain is critical for survival and has a major evolutionary advantage. This is because behaviours which cause pain are often dangerous and harmful, therefore they are generally not reinforced and are unlikely to be repeated. The classification of pain is complicated and there are many different ...

   What is the ascending pain pathway?

   • • The spinoreticular tract: fibres also decussate and ascend the contralateral cord to reach the brainstem reticular formation, before projecting to the thalamus and hypothalamus. There are many further projections to the cortex. This pathway is involved in the emotional aspects of pain. Figure 1 Ascending pain pathways.

   What is the pain pathway?

   • It will focus on how the pain pathway is initiated and processed within the spinal cord. Within the pain pathway there are 3 orders of neurones that carry action potentials signalling pain: First-order neurones – These are pseudounipolar neurones which have cells bodies within the dorsal root ganglion.

   What are the three stages of pain perception?

   • There are generally three main stages in the perception of pain. The first stage is pain sensitivity, followed by the second stage where the signals are transmitted from the periphery to the dorsal horn (DH), which is located in the spinal cord via the peripheral nervous system (PNS).

   4 Pain transmission can be modulated at a number of levels, including the dorsal horn of the spinal cord and via descending inhibitory pathways. 5 The spinothalamic and spinoreticular tracts are important ascending pain pathways 6 Neuropathic pain can be spontaneous and is often described as burning, shooting, or stabbing

   This article provides an overview of the physiological mechanisms of pain and the important pain pathways. We will discuss pain receptors, transmission of pain signals to the spinal cord and pain pathways within the spinal cord. We will look at how pain can be modulated at different levels along the pathway, and the sites of action of analgesic ...

   Vol. 16, No. 3, July-Sept 2005 PAIN PROCESSING 279 Figure 1. Ascending pain pathway. The ascending pain pathway transmits nociceptive information from peripheral tissues (1) via a primary afferent nerve fiber, which enters the spinal cord in the dorsal horn (2) where it synapses with a second-order neuron. The second-order neuron travels up
