Which of the following is NOT a characteristic of the spinal cord?
A. it runs through the VERTEBRAL column
B. It extends just below the rib cage
C. it uses spinal nerves to connect to the PNS
D. it has a dorsal and ventral root at each end
THANK YOU SO MUCH FOR HELPING!!!!!!!!!!!!!
i would really appreciate it if you could give me the source of your answer as well <3 <3
It extends much further than the rib cage. Google "spinal cord".
Oh, thank you so much for asking! I've been dying to share some spinal humor. The answer to your question is B. It doesn't extend just below the rib cage because the spinal cord actually ends around the first or second lumbar vertebra, which is a bit higher up. So it's like the spinal cord got tired after all that running through the vertebral column and decided to take a break before reaching the rib cage.
As for the source of my answer, you won't find it in any books or journals. It comes straight from the depths of my clownish brain. But don't worry, I do my research and try to provide accurate information. Just in a slightly silly way!
The correct answer is B. It extends just below the rib cage.
The spinal cord runs through the vertebral column, uses spinal nerves to connect to the peripheral nervous system (PNS), and has a dorsal and ventral root at each end. However, it does not extend all the way down to the rib cage.

The correct answer is B. It extends just below the rib cage.
To determine the correct answer, we need to understand the characteristics of the spinal cord. Let's go through each option:
A. The statement "it runs through the vertebral column" is true. The spinal cord passes through a canal formed by the stacked vertebrae of the vertebral column.
B. The statement "it extends just below the rib cage" is not true. The spinal cord actually extends from the base of the skull down to about the level of the first or second lumbar vertebra, which is roughly at the waistline.
C. The statement "it uses spinal nerves to connect to the PNS" is true. The spinal nerves arise from the spinal cord and connect it to the peripheral nervous system (PNS), allowing communication between the spinal cord and the rest of the body.
D. The statement "it has a dorsal and ventral root at each end" is true. The spinal cord has a pair of dorsal roots and a pair of ventral roots at each end. The dorsal roots carry sensory information from the body to the spinal cord, while the ventral roots carry motor signals from the spinal cord to the body.
Therefore, option B is the correct answer, as it does not correspond to a characteristic of the spinal cord.
