Original source text (layout and all choices are preserved in the source panel below):
The diagram below shows the different types of spinal nerves occurring in pairs and
some information about them.
Sensory information from the skin on the left of
the body ascends through the left side of the
spinal cord.
Motor neurons on the left side of the spinal cord
control contraction on the left side of the body.
Pain information from the skin on the left side
of the body ascends through the right side of
the spinal cord.
-Cervical nerves generally stimulate muscle
movement in your neck, shoulder, arm and
hand
-Thoracic nerves help control your rib cage,
lungs and diaphragm, and the muscles that
help you breathe
-Lumbar nerves control pain signals and the
movements of your lower limbs.
- Sacral nerves provides motor and sensory
nerves for most of the lower leg, the entire foot,
and part of the pelvis
A man who got into a vehicular accident a few days ago does not feel pain when a pin is
inserted into his left big toe. Which of the following can be predicted?
A. The nerves exiting the spinal cord at C6 are damaged.
B. The nerves entering the spinal cord at C6 are damaged.
C. The right side of the spinal cord at L5 is damaged
D. The left side of the spinal cord at T1 is damaged.
