How does the babinski reflex in infants?
its an extensor in the great toe, ankle joint with fanning of the other fingers till 2 years of age
Is corticospinal tract an indirect descending tract?
no
What damage lateral corticospinal can cause?
It's a specific type of spinal cord (back) injury. The corticospinal tract provides the most direct pathway over which the cerebral cortex controls movement. Damage in this area often results in paralysis or loss of muscle control.
What spinal tract might be damaged if lack of voluntary movement is observed?
lateral corticospinal tract -this would be the most major one anterior corticospinal tract - to a lesser extent a lesion of the rubrospinal tract would affect voluntary movement but not cause a lack of it
What are the causes and clinical manifestations of Millard-Gubler syndrome?
It's due to pontine lesion that destroys abducens nerve, facial nerve and corticospinal tract of one side.paralysis of lateral rectus muscle on the same side = due to damaged abducens nerveparalysis of facial expression muscles, and loss of other functions on the same side = due to damaged facial nerveparalysis of contralateral limbs = due to damaged corticospinal tract

What is lateral corticospinal tract?
Lateral corticospinal tract is the part of pyramidal tract that consists of crossed pyramidal fibres. So, it's also called as "crossed pyramidal tract".as for anterior corticospinal tract, it consists of uncrossed pyramidal fibres.
Is corticospinal tract an indirect descending tract?
no
What track is the major descending voluntary motor tract?
The corticospinal tract
What causes a Babinski's Reflex?
Babinski's sign is caused by a lesion in the corticospinal tract (UMN) that produces a characteristic pathological sign of extension of the great toe and fanning of the remaining toes. This also occurs in infants before the corticospinal tract is fully developed, in adults during sleep, or sometimes in adults after strenuous walking or running.

It's a specific type of spinal cord (back) injury. The corticospinal tract provides the most direct pathway over which the cerebral cortex controls movement. Damage in this area often results in paralysis or loss of muscle control.
What spinal tract controls signals the control handwriting?
tectospinal tracts
What spinal tract might be damaged if lack of voluntary movement is observed?
lateral corticospinal tract -this would be the most major one anterior corticospinal tract - to a lesser extent a lesion of the rubrospinal tract would affect voluntary movement but not cause a lack of it
Which spinal tract regulates voluntary motor control of skeletal muscles on the opposite side of the body?
Lateral Corticospinal Tract
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.
The pyramidal tract is the major descending voluntary motor tract?
the corticospinal tract and the pyramidal spinal tract are the same tract. yes this tract is the main voluntary motor tract, remember that this tract split in two after the decussation of pyramids (hence the term pyramidal tract) the fibres that do decussate create the lateral portion which innervates the limbs, shoulders and neck the fibers that dont decussate here continue ipsilaterally creating an anterior/ventral portion which innervate the truck, these eventually do decussate at their spinal exit level
What is the difference between corticobulbar tract and cortico spinal tract?
corticospinal tracts are the tracts of the upper motor neurons which originate in the cortex,(precentral gyrus). They terminate in the spinal cord by synapsing with the lower motor neurons either directly or through an interneuron. lesion to the corticospinal tract results in Spastic paralysis on the opp side if the lesion is above pyramidal decussation or before crossing over. Positive Babinski's sign loss of fine coordination in the distal limbs such as piano playing or typing
