Part II
Will require you to use your lecture book for information. You may have to use other resources such as lab books or google searches.
CNS
A. Does the central nervous system mean brain only?
B. How is the spinal cord protected?
C. Does the development and structure of spinal vertebrae, intervertebral discs, and joints produce a balance of protection and movement? Explain? Explain what would happen if we were solid bone without any joints? Would it be more protective? What would happen if we had less bone protecting the spinal cord, would we have greater movement?
D. Is the brain protected well from outside trauma? What happens to the soft squishy brain if there is swelling or an accumulation of fluid inside the cranium? What is this condition called?
E. T/F – The brain stem controls are basic functions like breathing and heart rate?
F. Are there specialized areas of the brain? Please give three examples and what specialized functions they perform?

L. Could a person have vision changes, headaches, sleeping difficulty or memory loss after a concussion? Please explain.
Nerves
The following questions involve named nerves from the brachioplexus.
References for following questions.
1. Radial Nerve controls finger extension.
2. Median nerve controls thumb opposition
3. Ulnar Nerve controls 5th digit finger flexion.
Watch Ulnar Nerve in Hand
Upper Extremity Nerves
Read and watch video on
A. A motor neuron leaves the spinal cord and travels to a muscle. If the motor neuron that leaves the cervical spine and travels down to the right little finger is severed at the elbow, what would be the resulting symptoms?
B. What happens when you bump your “funny bone” against the wall? What do you feel in your little finger? What nerve is involved?
C. Does the ulnar nerve have sensory fibers, motor fibers, or both? Please explain.
D. What if a fall fractured the olecranan process and moderately damaged the ulnar nerve, what symptoms would you have in your hand?
An entrapment is a term that describes compression on a nerve or artery that is causing symptoms. For example, carpal tunnel is an entrapment of the median nerve which causes numbness, tingling, or weakness in the first three digits. Removing the compression or entrapment allows the nerve to heel and return to normal functions.
E. Read and watch the video about Tunnel of Guyon Syndrome and read the page about Cubital Tunnel Syndrome
What are common causes of this syndromes? What are the resulting symptoms?
How does this look and act different than ulnar nerve compression at the elbow? What symptoms would be present in cubital tunnel syndrome that would not be found in Tunnel of Guyon syndrome?
F. What happens in Saturday Night Palsy? What are the signs and symptoms? How is it different than ulnar nerve entrapment? What fingers are affected? Is there any muscle weakness or sensation loss?
G. Thoracic outlet syndrome commonly occurs in two locations because of different muscle spasms. Pectoralis minor spasms or scalene muscle spasms can compress the artery and nerves as it travels from the neck and into the shoulder resulting in symptoms. What are the symptoms? Does it affect the entire hand and all the fingers, or only a few?
Carpal Tunnel Syndrome and Treatment vs Thoracic Outlet.
What nerve is compressed in carpal tunnel syndrome? Can it only be entrapped in one place?
How is thoracic outlet syndrome different than carpal tunnel? How are they similar? What would be two of the most obvious patient symptoms that distinguishes between carpal tunnel and thoracic outlet syndrome?
I. What nerve controls finger extension? Would a compression of this nerve cause weakness in finger extension and finger flexion? Why not?
J. If a friend complains of clumsiness in their hands with repetitive movement, weakness in thumb strength, and tingling in their second and third fingers; do you suspect damage to their ulnar nerve? If not, what nerve do you suspect?
