If an individual is suffering from cerebral palsy, what difficulty will occur in the motor system?

A. The axon bundles of the corticospinal tract are blocked from crossing to the opposite side of the body

B. Tactile feedback is lost

C. Signals from the upper motor neurons cannot reach the lower motor neurons, causing spastic contractions

D. None of the above

If an individual is suffering from cerebral palsy, they are most likely have problems in signals from the upper motor neurons that cannot reach the lower motor neurons, causing spastic contractions

Answer: Option C

Explanation:

Cerebral palsy is a motor neuron disease that mostly affects the children of years 3-5. Spastic contraction is a state in which the muscles are contracted causing stiffness.

That, in turn, affects the normality of movements of the person. Cerebral palsy causes Spastic contraction with the affected person. The Spastic Contraction is due to the absence of communication between the upper and lower motor neurons.

They send signals to the organs of the body to do actions. Thus the upper neurons are responsible for the actions and lower neuron supervises the movement of the face, arms, throat, etc.

The actions like walking or chewing from the upper neurons sent to the lower neurons. The interruption of the signal or communication will result in spastic.
