isn’t it all twisted out of position when you exercise?
12. Susan falls down a flight of stairs and suffers spinal cord damage due to hyperextension of
the cord during the fall. The injury results in edema of the spinal cord between C5-C8 with
resulting compression of the anterior horn cells of the spinal region. What symptoms would
you expect to observe because of this injury?

located in the lumbar region. What might she experience on her lower limbs?
14. Spinal cord injuries can be referred to as complete or incomplete. A complete spinal cord
injury refers to complete nerve damage at a particular level of the spinal cord. In incomplete
spinal cord injury, there is only partial damage at the level of injury of the spinal cord. What
might be the difference in effects on function and sensation in each of these types of spinal
cord injury?
15. Jerry has a condition known as Hydrocephalus. This is a condition in which fluid accumulates
in the brain, enlarging the head and even causing brain damage. It is known as water on
the brain.His physician, must draw some of this fluid, also known as cerebral spinal fluid
to check for any abnormality. She draws the fluid right under his L3 vertebra. Why is this the
case? Why doesn’t she draw the fluid from higher up?

Information is received by the dorsal root and sent out by the
ventral root.
It is held in place by the denticulate ligaments to keep it from
moving side to side.
Susan will have trouble moving the upper limbs.
Grandma will have trouble moving her lower limbs.
In a complete spinal cord injury there is no sensation and no
movement, while the incomplete loses either sensation or function.
It is drawn from under the L3 vertebrae so that it doesn't injure the
spinal cord.
