Module 6 Case Study AP1
Question 1
1 out of 1 points
Donna, a 42-year-old mother of two, has been experiencing intermittent tingling and
numbness
... [Show More] in both of her feet. She has also had trouble holding a pen while writing. In the
past few months, the tingling and numbness in her extremities seemed to subside on its
own, so she was not very concerned. Recently, though, the symptoms have spread to her
knees and thighs and are persisting.
Yesterday, she stumbled when getting out of bed in the morning. When she tried to stand,
her right leg was too weak to hold her weight and she fell again. She noticed that she
scraped her right knee during the fall, but does not feel any pain from the wound. Donna
notices that she has blurry vision and thinks that might be the reason she fell.
All of the following indicate sensory deficits EXCEPT:

Answer:
Muscular
weakness
Question 2
Needs Grading
Donna does not feel the wound on her knee. In a normal situation, describe how
this sensory input of a scraped knee would result in the feeling of pain.

Answer:
When you scrape your knee the site has damage to the tissues which is
registered by nociceptors, or pain receptors. These pain receptors are the
ending points of a neuron and send an electrical signal up the axon or nerve
fiber to a bundle of other nerve fibers that creates a peripheral nerve. The
electrical signal travels up neurons in the peripheral nerve towards the neck
and reaches the spinal cord. At this point the electrical signal travels to
another neuron through a small gap called a synapse. This is able to be
done through neurotransmitters. The electrical signal then travels up the
nerve fiber of the spinal cord and relays the sensory input information to
the brain and allows us to feel and react to the pain.
