The "marginating pool" of neutrophils is located: a) in the kidneys b) in the tissue c) next to marrow sinuses d) on the blood vessel walls D: The marginating pool designates white blood cells located along the vessel endothelium, ready to migrate to a site of injury or infection.

One of the primary glands responsible for lymphocyte origination in the infant is the a) Thymus gland b) Adrenal gland c) Thyroid gland d) Pituitary gland A: Lymphocytes originate not only from the bone marrow, but also from the thymus, and they have a distinctive place on the hematopoietic maturation chart.
The initial appearance of specific granulation in the granulocytic series is predominantly seen in the: a) Promyelocyte b) Metamyelocyte c) Myelocyte d) Eosinophil C: Differentiating characteristics: small pink-purple granules for neutophilic myelocyte, nucleus stains deeper color, granular pattern to the chromatic eccentric nucleus, with visible golgi apparatus seen as a lighter area near nucleus
