The Babinski response, or Babinski reflex, is a neurological sign observed in infants and in some adults with certain neurological conditions. It is characterized by the extension and fanning of the toes when the sole of the foot is stroked along the outer edge. In infants, this response is normal and indicates healthy neurological development, while in adults, a positive Babinski response may suggest damage to the corticospinal tract. This reflex is often used in neurological examinations to assess the integrity of the nervous system.

What is negative babinski?
there is no such thing as a negative babinski reflex, but a "negative" babinski is a physiological response to a mechanical stimulus of the foot plant. it is usually called plantar reflex or, flexor plantar response. this is a test used to determine the continuity of the corticospinal tract, and sould therefore be "negative" in healthy subjects. infants until 24 months, may show a positive babinski due to the incomplete growth of the cerebrum.
A negative babinski reflex is?
A negative Babinski reflex is when the big toe move downward and the other toes fan out. It is a normal response seen in adults, indicating proper nerve function in the lower limbs. This response is different from the abnormal response seen in infants where the big toe moves upward and the other toes fan out, known as a positive Babinski reflex.
What is a pathological response?
A pathological reflex is an unexpected/abnormal response to stimulus. For instance, a positive babinski reflex is a pathological reflex.
Is the babinski reflex somatic?
Yes, the Babinski reflex is a somatic reflex. It is a normal response in infants where the big toe extends and the other toes fan out when the sole of the foot is stroked. In adults, a Babinski reflex is considered abnormal and can indicate damage to the corticospinal tract in the central nervous system.

It Is The Babinski Reflex
In an adult curling under of all the toes in response to gentle stroking of the lateral outer margin of the sole is?
The Babinski reflex is a normal response in infants, where the big toe curls upward and the other toes fan out in response to stroking the lateral outer margin of the sole. However, in adults, this response is abnormal and can indicate neurological damage or dysfunction in the corticospinal tract.
What is the medical term for a pathological response to stimulation of the plantar surface of the foot indicated by dorsiflexion of toes?
Babinski sign or reflex
What does a positive babinski reflex mean?
Dorsiflexion of the Big toe indicates a positive Babinski response. This is mostly seen from a central nervous system lesion in the corticospinal tract, but is also seen in unconscious states from drug or alcohol intoxication or the postictal period following a seizure.
What is the babinski sign explain its significance?
The Babinski sign is a neurological reflex observed when the sole of the foot is stroked, resulting in the big toe extending upward and the other toes spreading apart. In infants, this response is normal due to their immature nervous systems. However, in adults, the presence of the Babinski sign may indicate damage to the corticospinal tract or other neurological disorders, as the expected response in adults is for the toes to curl downward. Its significance lies in its use as a diagnostic tool for assessing neurological function.
Bilateral Babinski sign?
The Babinski sign is a reflex that happens when the bottom of a persons foot is stroked and the big toe curls up in response. This reflex is usually present in babies for the first 6 or so months of their life and goes away once a certain group of nerves running from the brain to muscles in the lower limbs is fully developed and functions to block the Babinski reflex.The Babinski can reoccur in people if this group of nerves gets damaged and is not able to block this reflex anymore. Strokes, aneurysms, and tumors are some things that can cause this.Bilateral just means that the reflex is present in both feet.
Is a Babinski reflex considered a superficial reflex?
Yes, the Babinski reflex is considered a superficial reflex because it involves a response from the skin’s surface rather than from deep within the body. It is elicited by stroking the sole of the foot and observing the movement of the toes, which helps to assess the integrity of the central nervous system.
Strokes and toes reflexes?
I believe you may be asking about the Babinski reflex. The Babinski reflex is a normal reflex for the first year or so of life, when the brain is not fully myelinated. It is an upward extension of the big toe and a fanning out of the remainder of the toes. As was mentioned earlier, this reflex normally goes away by the first year of life and when one tries to elicit the response after it goes away, one should see a downward flexion of the toes. In stroke (or spinal cord injury) involving the leg, the Babinski reflex may come back. This is a sign of upper motor neuron injury. The injury can be anywhere from the cerebral cortex to the spinal cord, so a Babinski reflex by itself does not signify stroke.
