Answer:
The correct answer is "grey; central canal".
Explanation:
Grey matter refers to an area of the brain, brainstem and cerebellum comprised of unmyelinated neurons and other cells that has given its name for having a pinkish-grey color in the living brain. Grey matter is also present in the spinal cord in an are of three grey columns that are H-shaped and it is located around the central canal filled with cerebrospinal fluid
Grey matter is indeed the H-shaped portion of the brain stem that surrounds the central canal, which would be filled with cerebrospinal fluid.
Spinal cords:
- Grey matter describes an area of the brain, brainstem, or cerebellum made up mainly of unmyelinated two neurons.
- It has a pinkish-grey color in the living brain.
- It can also be found in the spinal cord, in the form of three H-shaped grey pillars that surround the central cavity, which is filled with cerebrospinal fluid.
- A spinal cord is a tube-like ring of tissue that runs around the back of the neck.
Therefore, the final answer is "grey and central canal".
