What will happen if we don’t have reflex action?
If the reaction is exaggerated or absent, it may indicate a damage to the central nervous system.
Most reflexes go completely unnoticed because they don’t involve a visible and sudden movement.
Body functions such as digestion or blood pressure, for example, are all regulated by reflexes..
What is abnormal reflex?
An abnormal response is slower and consists of extension of the great toe with fanning of the other toes and often knee and hip flexion. This reaction is of spinal reflex origin and indicates spinal disinhibition due to an upper motor neuron lesion.
What is the fastest reaction time in the world?
around 0.15 sThe fastest possible conscious human reactions are around 0.15 s, but most are around 0.2 s.
How do you test for weak legs?
Rising from a squatting position or stepping onto a chair tests proximal leg strength; walking on the heels and on tiptoe tests distal strength. Pushing with the arms to get out of a chair indicates quadriceps weakness. Swinging the body to move the arms indicates shoulder girdle weakness.
What can affect reflexes?
Many factors have been shown to affect reaction times, including age, gender, physical fitness, fatigue, distraction, alcohol, personality type, and whether the stimulus is auditory or visual.
How fast are human reflexes?
The typical reaction time for a human is about 250 milliseconds—meaning it takes you about a quarter of a second after you see something to physically react to it.
Who has the fastest reflex?
The startle reflex of Condylostylus fly most certainly constitutes the fastest in insects, as it is 3–10 times faster than the previously reported reflex response times.
How can I improve my reflexes?

Why are my reflexes so fast?
Brisk reflexes may develop when neurons deteriorate. These neurons are also known as the upper motor nerve cells. Other causes of brisk reflexes are associated with neurological conditions, including: … This nervous system disorder develops when your body attacks its own neurons and affects movement.
What does no reflexes in legs mean?
When reflex responses are absent this could be a clue that the spinal cord, nerve root, peripheral nerve, or muscle has been damaged. When reflex response is abnormal, it may be due to the disruption of the sensory (feeling) or motor (movement) nerves or both.
What exercises improve balance?
Or, stand up from a seated position without using your hands. Or try walking in a line, heel to toe, for a short distance. You can also try tai chi — a form of movement training that may improve balance and stability and reduce the incidence of falls.
What is the fastest reflex in the human body?
There are many various reflexes that can occur simultaneously during a startle response. The fastest reflex recorded in humans happens within the masseter muscle or jaw muscle. The reflex was measured by electromyography which records the electrical activity during movement of the muscles.
What are 3 reflexes in humans?
Kinds of human reflexesBiceps reflex (C5, C6)Brachioradialis reflex (C5, C6, C7)Extensor digitorum reflex (C6, C7)Triceps reflex (C6, C7, C8)Patellar reflex or knee-jerk reflex (L2, L3, L4)Ankle jerk reflex (Achilles reflex) (S1, S2)
How does exercise improve reaction time?

What can slow down your reflexes?
Physical changes in nerve fibers slow the speed of conduction. And the parts of the brain involved in motor control lose cells over time. But the effect of age on reflexes and reaction time varies greatly from person to person. You can actually slow down—even reverse—the effects of aging by staying physically active.
What causes loss of reflexes?
Peripheral neuropathy is today the most common cause of absent reflexes. The causes include diseases such as diabetes, alcoholism, amyloidosis, uremia; vitamin deficiencies such as pellagra, beriberi, pernicious anemia; remote cancer; toxins including lead, arsenic, isoniazid, vincristine, diphenylhydantoin.
At what age are reflexes best?
The next time some twenty-something complains that they feel old, you can reassure them that their feelings are, in fact, not ridiculous. After studying 3,305 people ages 16 to 44, researchers found that the brain’s response time begins to decline at age 24.

Who has a faster reaction time male or female?
Gender. A review of the literature on the influence of gender on RT shows that in almost every age group, males have faster RTs as compared to females, and female disadvantage is not reduced by practice. [13,14,15] Researches done by Misra et al.  also showed that males responded faster than females.
