• sensory
  • However, in that case, the sensory limb of the reflex is the CN V (trigeminal nerve). (wikipedia.org)
  • This is because the sensory component is intact on both sides, but only the motor nerves supplying one side of the soft palatine and pharyngeal muscles is working, therefore the contraction of the muscles in the reflex is asymmetrical. (wikipedia.org)
  • The reflex is tested as part of the neurological examination to assess the sensory and motor pathways within the C6 and C7 spinal nerves. (wikipedia.org)
  • An absence of reflex can be an indicator of several medical conditions: Myopathy, neuropathy, spondylosis, sensory nerve disease, neuritis, potential lower motor neuron lesion, or poliomyelitis. (wikipedia.org)
  • However, the brain will receive the sensory input while the reflex is being carried out and the analysis of the signal takes place after the reflex action. (wikipedia.org)
  • A reflex arc, then, is the pathway followed by nerves which (a.) carry sensory information from the receptor to the spinal cord, and then (b) carry the response generated by the spinal cord to effector organ(s) during a reflex action. (wikipedia.org)
  • When a reflex arc in an animal consists of only one sensory neuron and one motor neuron, it is defined as monosynaptic, referring to the presence of a single chemical synapse. (wikipedia.org)
  • Bradycardia
  • Upon initiation of the reflex, changes occur: Bradycardia is the response to facial contact with cold water: the human heart rate slows down ten to twenty-five percent. (wikipedia.org)
  • In reflex bradycardia, blood pressure is reduced by decreasing cardiac output (CO) via a decrease in heart rate (HR). An increase in blood pressure can be caused by increased cardiac output, increased total peripheral resistance, or both. (wikipedia.org)
  • Acetylcholine then binds to M2 muscarinic receptors, causing the decrease in heart rate that is referred to as reflex bradycardia. (wikipedia.org)
  • Bradycardia, junctional rhythm and asystole, all of which may be life-threatening, can be induced through this reflex. (wikipedia.org)

  • efferent
  • Signaling in the efferent arc of the inflammatory reflex, termed the "Cholinergic anti-inflammatory pathway," provides a regulatory check on the innate immune system response to invasion and injury. (wikipedia.org)
  • vagus nerve
  • In certain cases, absence of the gag reflex and pharyngeal sensation can be a symptom of a number of severe medical conditions, such as damage to the glossopharyngeal nerve , the vagus nerve , or brain death . (wikipedia.org)
  • The reflex is mediated by nerve connections between the ophthalmic branch of the trigeminal cranial nerve via the ciliary ganglion, and the vagus nerve of the parasympathetic nervous system. (wikipedia.org)
  • Babinski
  • When performing the Babinski reflex test, the doctor will gently stroke the outer soles of the person's feet with the mallet while checking to see whether the big toe extends out as a result. (encyclopedia.com)
  • A normal response to the Babinski reflex test depends upon the age of the person being examined. (encyclopedia.com)
  • While first described in the medical literature by Babinski in 1896, the reflex has been identified in art at least as early as Botticelli's Madonna and Child With an Angel, painted in the mid 15th Century. (wikipedia.org)
  • The Hoffmann's reflex is sometimes described as the upper limb equivalent of the Babinski sign because both indicate upper motor neuron dysfunction. (wikipedia.org)
  • callbacks
  • Reflex provides adapters for nearly every kind of callback that exists, including condvar-like promises that allow Reflex objects to be used inline without callbacks at all. (cpan.org)
  • physiological
  • physiological response to immersion of air-breathing vertebrates The diving reflex, also known as the diving response and mammalian diving reflex is a response to immersion that overrides the basic homeostatic reflexes, which is found in all air-breathing vertebrates. (wikipedia.org)
  • The autonomic nervous system's physiological state (see below) leading to loss of consciousness may persist for several minutes, so If sufferers try to sit or stand when they wake up, they may pass out again The person may be nauseated, pale, and sweaty for several minutes or hours Reflex syncope occurs in response to a trigger due to dysfunction of the heart rate and blood pressure regulating mechanism. (wikipedia.org)
  • One account for these physiological responses is the Bezold-Jarisch reflex. (wikipedia.org)
  • Physiological and Pharmacological modulation of the human nociceptive withdrawal reflex (PDF) (PhD Thesis). (wikipedia.org)
  • neonates
  • This reflex is especially sensitive in neonates and children, particularly during strabismus correction surgery. (wikipedia.org)
  • Generally
  • Closely related to the gag reflex, in which food or other foreign substances are forced back out of the pharynx , swallowing generally pushes food through the digestive system into the stomach. (wikipedia.org)
  • refers
  • The red reflex refers to the reddish-orange reflection of light from the back of the eye, or fundus, observed when using an ophthalmoscope or retinoscope. (wikipedia.org)
  • The traditional red reflex refers to visualizing each eye individually. (wikipedia.org)
  • response
  • Touching the soft palate can lead to a similar reflex response. (wikipedia.org)
  • Reflex syncope occurs in response to a trigger due to dysfunction of the heart rate and blood pressure regulating mechanism. (wikipedia.org)
  • The accommodation reflex (or accommodation-convergence reflex) is a reflex action of the eye, in response to focusing on a near object, then looking at distant object (and vice versa), comprising coordinated changes in vergence, lens shape and pupil size (accommodation). (wikipedia.org)
  • Preliminary evidence indicates that the bilateral carotid bodies detect the decreasing oxygen and rising carbon dioxide levels in blood during breath-holding, then send signals to the brain to regulate the entire cardiovascular response of the diving reflex. (wikipedia.org)
  • Many reflex hammers taper at the end of the handle to a point which was used for testing the plantar response in the past, however, due to the tightening of infection control regulation this is no longer recommended. (wikipedia.org)
  • involve
  • Reflex bleeding must therefore involve blood with a certain je ne sais quoi (and do not want to know). (everything2.com)
  • Others of these involve just a couple of synapses to function (e.g., the withdrawal reflex). (wikipedia.org)
  • Cough
  • The bronchi and trachea are so sensitive to light touch that slight amounts of foreign matter or other causes of irritation initiate the cough reflex. (wikipedia.org)
  • The cough reflex can be tested by inhaling air with nebulized 200┬Ámol/l capsaicin. (wikipedia.org)
  • Cough Reflex: http://www.healthhype.com/cough-reflex-physiology-process-ear-cough-reflexes.html Ganong WF, "Chapter 36. (wikipedia.org)
  • assess
  • In medicine, reflexes are often used to assess the health of the nervous system. (wikipedia.org)
  • It is difficult to assess the effectiveness of the technique due to the low incidence of some of the pathology the red reflex is used to detect. (wikipedia.org)
  • There are two techniques used to assess the red reflex listed below. (wikipedia.org)
  • contrast
  • In contrast, triggering the reflex is sometimes done intentionally to induce vomiting, by those who suffer from bulimia nervosa . (wikipedia.org)
  • In contrast, the Bainbridge reflex responds to changes in blood volume. (wikipedia.org)
  • absence
  • Absence of a reflex (areflexia): If no reflex is elicited then it is essential to try again with reinforcement, with the patient clenching his or her teeth just as the reflex hammer strikes. (wikipedia.org)

  • This is known as Arnold's reflex. (wikipedia.org)
  • muscles
  • These results suggest that the muscles that control the gag reflex remain independent of those that control normal swallowing. (wikipedia.org)
