polio virus is an entero virus, affecting intestine. but "About 1 percent of polio, virus invades the body and become an invasive disease, it can affect nervous system and cause paralytic polio. the nervous system may be affected at the spinal cord (polio myelitis, or spinal polio) or brain stem (bulbar polio) or both.

30. Which of the following is incorrect?
a. The adult medullary cavity contains yellow marrow. b. The infant medullary cavity contains yellow
marrow. c. The infant medullary cavity contains red marrow. d. The adult medullary cavity contains
adipose tissue

The test says its a but I don't think any of these are correct. What would be the correct answer though?

A and D are automatically eliminated because they basically say the same thing. C is correct, so I'd say it's B from process of elimination. Also I know that at birth, all bone marrow is red, so yeah it's B.

I agree with Locoholic. As you become an adult the RBM is gradually replaced by fatty YBM. Soon enough, RBM is only found in certain areas of the body.

At my last competition I used size 3 arial narrow, which is about the smallest I can easily read. I also don't have immediate access to a laser printer but mine still does the job well.

But is there absolutely zero yellow bone marrow in infant medullary cavity?
