Would you withdraw CSF if the needle were accidentally inserted into the epidural space instead of the subarachnoid
castortr0y [4]

Answer: No. You would not withdraw CSF if the needle is in the epidural space.

Explanation: There are 3 spaces that cover the spinal cord, which are epidural, subdural and subarachnoid spaces. The epidural space is the outer most space while the subarachnoid space is the inner most space. CSF flows from the brain where it is produced to the spinal cord. In the spinal cord it flows only in the subarachnoid space. Thus you would not be able to withdraw CSF if the needle is in the epidural space.

andrew11 [14]

Answer:

Running away from a fierce dog

Explanation:

An example of an emergency situation will be of a person fleeing away from a fierce dog. Suppose a person suddenly comes across a fierce dog. The response will be to run or flee. The body generates this response as a result of Adrenalin released by the adrenal glans up next to the kidneys. The hormone is known as the flight or fight hormone. It effects the smooth and skeletal muscles, causing the increased supply of oxygenated blood. Also, the heart beats faster to pump more blood. The pupils of the eyes dilate and vision and alertness is increases.  

The predictions show a flight reaction.
