BABINSKI'S SIGN

PLANTAR REFLEX :-

 This is a reflex of the foot in which if we stroke the sole of the foot with a blunt object then the toes undergo plantar flexion(means downward projection of the toes in the direction of the ground). 

BABINSKI'S SIGN :- 

Abnormality in plantar flexion is called extensor reflex which is also called babinski's sign.

°In Babinski's sign the hallax(great toe) moves in upward direction and there will extension between the toes(other than great toe) which appears like a fan so also called fanning movement of the toes.(babinski's test)

CAUSE :-

 Damage to corticospinal tract which is a pyramidal tract which comes under descending tract & Even UMNL(upper motor neuron lesion)

             •UMN : These are neurons which are present in brain and the spinal cord whose lesion causes :-

             #Damage to more than 1 muscles .

             #Spasticity

             #Superficial reflex like cremastric                         reflex,anal reflex, abdominal reflex                     are affected others reflexes are                           present.

            #Presence of extensor reflex also                        called babinski sign.
