Question

Quizplus · Accepted Answer

A sternal puncture is a procedure where a needle is inserted through the sternum (breastbone) to extract a sample of bone marrow. Red bone marrow, which is responsible for the production of blood cells, is located in the interior of bones such as the sternum. Therefore, a sternal puncture is used to obtain a sample of red bone marrow. Options A and B are incorrect because fibroblasts and osteoblasts are not typically obtained through sternal punctures. Option D is incorrect because yellow bone marrow, which stores fat, is not found in the sternum.
