Reflex bradycardia. Reflex bradycardia is a bradycardia (decrease in heart rate) in response to the baroreceptor reflex, one of the body's homeostatic mechanisms for preventing abnormal increases in blood pressure. In the presence of high mean arterial pressure, the baroreceptor reflex produces a reflex bradycardia as a method of decreasing ...
This is achieved by applying pressure to certain points on the feet. “Relaxation is probably the biggest benefit [of foot reflexology],” says Martinez. “Reflexology helps by increasing blood ...
The reflex — also known as the startle reflex — reaches a peak when your baby reaches 1 month and begins to disappear when they turn 2 months old. Several things may set off this reflex: a ...
The Hoffman test determines whether a person has spinal cord damage. During this quick test, you hold out one of your arms and open your palm facedown, extending your fingers in front of you. Your ...
A reflex arc is a neural pathway that controls a reflex. In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain. The brain will receive the input while the ...
Oculocardiac reflex. The oculocardiac reflex, also known as Aschner phenomenon, Aschner reflex, or Aschner–Dagnini reflex, is a decrease in pulse rate associated with traction applied to extraocular muscles and/or compression of the eyeball. [1] The reflex is mediated by nerve connections between the ophthalmic branch of the trigeminal ...
A reflex is a response to a stimulus and that occurs without conscious thought. Examples of adult reflexes include pulling your hand away from a hot stove and jerking your lower leg when the area ...
003429. In medicine, the caloric reflex test (sometimes termed 'vestibular caloric stimulation ') is a test of the vestibulo-ocular reflex that involves irrigating cold or warm water or air into the external auditory canal. This method was developed by Robert Bárány, who won a Nobel prize in 1914 for this discovery.
