Students have asked these similar questions
The thoracic spinal cord has the smallest dorsal horn area because:
a.
the trunk is the most innervated area of the body and therefore there are more projections into the dorsal horn there.
b.
the trunk is the least innervated area of the body and therefore there are fewer projections into the dorsal horn there.
c.
most of the descending upper motor neurons have already entered the ventral horn.
d.
There are many motor neurons to control the small muscles around the spine.
Where is the anterior (ventral) root located in the sequence of structures through which motor impulses pass as they descent from the brain and leve the spinal cord?
A. Between anterior (ventral) gray horn and spinal nerve
B. Between spinal nerve and posterior (dorsal) root ganglion
C. Between anterior (ventral) gray horn and posterior (dorsal) gray horn
D. Between white column and posterior (dorsal) gray horn
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?
