   Mar 17, 2023 · An essential feature of the central nervous system (CNS), the spinal cord lies within the spinal column and extends from the brainstem to the lower back through the vertebral foramen of the vertebrae. In adults, the spinal cord terminates in the lumbar region at L1-L2, the conus medullaris.[1] Below this, the vertebral canal contains the "cauda equina" or "horse's tail," a bundle of nerve roots.

   Oct 1, 2022 · Pain is an unpleasant experience that results from both physical and psychological responses to injury. A complex set of pathways transmits pain messages from the periphery to the central nervous system, where control occurs from higher centres. Primary afferent pain fibres synapse with second-order neurons in the dorsal horn of the spinal cord ...

   Aug 16, 2023 · Spinal cord: Cross-section. Descending tracts are the pathways by which motor signals are sent from the brain to the spinal cord. They are also called motor tracts, due to their involvement in movement coordination. These tracts can be classified by their structural arrangement, into lateral and medial tracts.

   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 ...

   Feb 2, 2018 · Introduction. The somatosensory system endows animals with the ability to monitor their external and internal environment. It is composed of interoceptive (proprioceptive and autonomic) and exteroceptive (cutaneous) receptors and their associated afferent pathways that relay information about the body to the spinal cord, medulla and to brain structures including the cerebellum, parabrachial ...

   There are four main sensory pathways ascending the spinal column. First, there’s the spinothalamic tract which is divided into two parts. The lateral tract carries sensory information for pain and temperature, while the anterior tract carries information for crude touch and pressure. Next, there are two dorsal column tracts: the fasciculus ...

   Pain can be referred because signals from several areas of the body often travel through the same nerve pathways in the spinal cord and brain. For example, pain from a heart attack may be felt in the neck, jaws, arms, or abdomen. Pain from a gallbladder attack may be felt in the back of the shoulder.
