Question
Please answer the following questions:
7. Suppose that the left side of a patient's spinal cord as crushed at T5. How is the voluntary fine motor output of both legs affected? Would parasympathetic output be affected by this spinal cord injury? Why or Why not? Would a reflex be seen in either leg if the doctors hit his knee with a reflex hammer? Diagram this response. - Propose five separate and completely different experiments or observations they can perform or make to determine if it is skeletal or smooth muscle. Explain your reasoning for each experiment and expected results (if a picture is easier to explain, then draw a picture). Do NOT need to list the methods for the experiments, just the concepts and reasoning behind the experiments or observations. Must explain difference in both smooth and skeletal for EACH experiment.Explanation / Answer
On left side -extensive paralysis of upper motir neuron typwe due ti damage of crossed pyramidal tract .since some fibre of direct pyramidal tract of opposite site escape injury therefore some musclees on the same side of the lesions may not be paralysed.
On right side.-eitherno paralysis or paralysis of few muscles occur this is due to involvement if sone fibres of direct pyramidel tracts .
2.parasumpathetic nervous system has craniosacral outflow .
Sympathetic nervous syatem has thoracolumbar outflow.so it will nit affect parasympathetic system.
3it does not affact knee jerk reflex.
When tap on knee -increase length of muscle -stimulate muscle spindle-impulse vua IA and II fibres-enter spinal cord-directly synapse with the A alpha motor neuron which goes into muscle
