Ill do Upper: {Interrupted Corticospinal}
1)flaccid paralysis
2)spasticity with hyperreflexia
3)clonus
4)Babinski elicited
5)absent abdominal reflexes

Doing this in detail:
1)Initially the affected limb shows a flaccid paralysis with loss of tendon reflexes. Normal muscle tone is lost.
2)After days or weeks some return of voluntary muscle tone is gained. And we see spasticity and hyperreflexia.
3)Clonus may be elicited at the wrist/ankle
4)Babinski elicited
5)absent abdominal reflexes
most important{eventual spasticity, hyperreflexia, Babinski elicited}
For LMN at least remember:
muscle wasting, flaccidity/loss ot DTReflexes, fasciculations

i chechked the book....it's correct. there is inittial flaccidity becoz normally motor system is under the influnce of higher brain region. immediate cut off wud result in flaccidity but then the spindles gain there control and become hyperactive.
