Neuropathic pain has profound physiological effects on the brain which can manifest as psychological disorders. Rodent models where the social effects of chronic pain can be isolated from other factors suggest that induction of chronic pain can cause anxio-depressive symptoms and that particular circuits in the brain have a direct connection.
Peripheral neuropathy may be classified according to the number and distribution of nerves affected (mononeuropathy, mononeuritis multiplex, or polyneuropathy), the type of nerve fiber predominantly affected (motor, sensory, autonomic), or the process affecting the nerves; e.g., inflammation (), compression (compression neuropathy), chemotherapy ([[chemother completion.
' pain receptor ') is a sensory neuron that responds to damaging or potentially damaging stimuli by sending "possible threat" signals [1] [2] [3] to the spinal cord and the brain. The brain creates the sensation of pain to direct attention to the body part, so the threat can be mitigated; this process is called nociception.
The following is a list of nerves in the human body: Location. Distribution of the areas of the sensory roots upon the surface of the body.
While any nerve in the body may undergo inflammation, [10] specific etiologies may preferentially affect specific nerves. [11] The nature of symptoms depends on the specific nerves involved, neuritis in a sensory nerve may cause pain , paresthesia (pins-and-needles), hypoesthesia (numbness), and anesthesia , and neuritis in a motor nerve may ...
Many health conditions can cause autonomic neuropathy. Some common causes of autonomic neuropathy include: Diabetes, which is the most common cause of autonomic neuropathy, can gradually cause nerve damage throughout the body. Vitamin B 12 deficiency (pernicious anemia) Injury to nerves caused by surgery or radiation to the neck.
Lateral lemniscus is the first point of integration of sound and pain information. [16] Inferior colliculus (IC) aids in sound orienting to pain stimuli. [17] Superior colliculus receives IC's input, integrates visual orienting info, and uses the balance topographical map to orient the body to the pain stimuli. [18] [19]
The first 4 cervical spinal nerves, C1 through C4, split and recombine to produce a variety of nerves that serve the neck and back of head. Spinal nerve C1 is called the suboccipital nerve, which provides motor innervation to muscles at the base of the skull. C2 and C3 form many of the nerves of the neck, providing both sensory and motor control.
