The non-invasive test that can be used to test if the cribriform plate is severely damaged is called the pledget study.
CRIBRIFORM PLATE is the part of the ethmoid bone that forms the nasal cavity.
The olfactory nerve which is part of the cranial nerves passes through the small opening found in the cribriform plate.
A damage to the cribriform plate leads to cerebrospinal fluid (CSF) leak which usually comes out from the nose and ears.
Therefore to test if the cribriform plate is severely damaged, the pledget study is performed.
Pledget study is a non-invasive method of diagnosing a CSF leak.
To perform this test,
- Cotton pads called Pledgets are placed in the nostrils.
- If the leaking fluid contains CSF it will be detected.
The presence of CSF shows that there is damage to the cribriform plate.
This method is non invasive because it doesn't require the breaking or opening of any part of the body.

Explanation:
The vascular family refers to a group of vessels fed by a primary branch of the aorta or branches of the vessel that are being punctured. They are vessels that arise directly off the aorta or vessel puncture. For example, the in nominate defines one particular vascular family. First order is the main artery in a vascular family, second order is the branch off the main artery, while third order, is the next branch off the second order and so on.
Most woolly mammoths went extinct roughly 10,000 years ago amid a warming climate and widespread human hunting. But isolated populations survived for thousands of years after that on St. Paul Island in the Bering Sea and Wrangel Island in the Arctic Ocean
They would most likely die. They could also mate with other animals, thus creating a crossbreed
