Question

describe how spinal cord damage influences muscle activity or movement:

Answer 1

Spinal injury is the injury to the spinal cord.

It includes

1. Complete transduction
2. The incomplete transduction
3. The spinal hemisection
4. The disease of spinal cord

These are the main spinal injury

The spinal injury lead to the loss if function of the spinal center. Yes the sensory impulses sent to spinal cord will no longer travel up to the centre in brain and no response will occur . The motor neuron will not work anymore below the level of injury.

The reflex activity and the muscle movement below the injured are will be lost at the initial stage .

Then after few week the reflex activity return to normal and then small reflex activity will occur that is stage 2

Then after this the reflex activity will return but the muscle power below injury will be less in stage 3

The muscle power below the injured region reduce tremendously.
