Summary Introduction
To analyze:
The part of the spinal cord responsible for the condition of Cindy, a patient who has no pain sensation on the lower limb and left hip, while the sensation is felt normally in other parts of the patient.
Introduction:
In the human body, there are many sensory neurons that deliver information to central nervous system regularly. There are also a huge number of motor neurons that help the body to respond according to the stimulus. Both sensory neurons and motor neurons move in the spinal cord by different tracts. The sensory tracts deliver information to the brain from the periphery. The motor tracts deliver information to the periphery from the brain.

Peyton felt strange when she awoke one morning. She could not hold a pen in her right hand when trying to write an entry in her diary, and her muscles were noticeably weaker on the right side of her body. Additionally, her husband noticed that she was slurring her speech, so he took her to the emergency room. What does the ER physician suspect has occurred? Where in the brain might the physician suspect that abnormal activity or perhaps a lesion is located, and why?
