The functional kidney is associated with which embryonic organ? a. Metanephros c. Pronephros b. Mesonephros d. Endonephros ANS: A The functional kidney is associated with the metanephros. The kidney develops from three sets of structures: the pronephros (nonfunctional by the end of the embryonic period), mesonephros (nonfunctional), and metanephros (the functional kidney).

1. The area of the kidneys that contains the glomeruli and portions of the tubules is called the: a. Medulla c. Pyramids b. Cortex d. Columns ANS: B The cortex contains all the glomeruli and portions of the tubules of the kidneys. Although the other options are also located in the kidney, they do not contain the glomeruli.

. Diffuse axonal injuries (DAIs) of the brain often result in: a. Reduced levels of consciousness c. Fine motor tremors b. Mild but permanent dysfunction d. Visual disturbances ANS: A Focal brain injuries account for more than two-thirds of head injury deaths; DAIs accounts for less than one third. However, more severely disabled survivors, including those in an unresponsive state or reduced level of consciousness, have DAIs. The other options do not appropriately complete the stem. PTS: 1...

Which immunoglobulin (Ig) is elevated in atopic dermatitis? a. IgA c. IgE b. IgM d. IgG ANS: C In the acute phase of atopic dermatitis, inflammation is associated with the activation of T helper 1 (Th-1) cells with an overexpression of cytokines (interleukin [IL]Ð4, IL-5, and IL13) and chemokine ligand 1 (CCL1) and 18 (CCL18) with increases in IgE, eosinophils, and macrophages. The remaining options will not be elevated as related to atopic dermatitis. PTS: 1 REF: Page 1654 2. Which leu...

. Most cardiovascular developments occur between which weeks of gestation? a. Fourth and seventh weeks c. Twelfth and fourteenth weeks b. Eighth and tenth weeks d.

Hypersensitivity is best defined as a(an): a. Disturbance in the immunologic tolerance of self-antigens b. Immunologic reaction of one person to the tissue of another person c. Altered immunologic response to an antigen that results in disease d. Undetectable immune response in the presence of antigens ANS: C Hypersensitivity is an altered immunologic response to an antigen that results in disease or damage to the host. The other options are not accurate definitions of hypersensitivity. ...

1. Until the skeleton matures and adult stature is reached, where does growth in the length of bone occur? a. Epiphyseal line c. Epiphyseal cartilage b. Physeal plate d. Metaphyseal plate ANS: B Until the skeleton matures and adult stature is reached, growth in the length of bone occurs only at the physeal plate through endochondral ossification. PTS: 1 REF: Page 1592 2. Which skeletal deformity is normal at birth but generally disappears by 21 / 2 years of age? a. Genu varum (bowle...

. Which pathway carries sensory information toward the central nervous system (CNS)? a. Ascending c. Somatic b. Descending d. Efferent ANS: A Peripheral nerve pathways can be afferent (ascending) pathways that carry sensory impulses toward the CNS. The remaining options do not carry sensory information to the CNS. PTS: 1 REF: Page 448 2. Which type of axon transmits a nerve impulse at the highest rate? a. Large nonmyelinated c. Small nonmyelinated b. Large myelinated d. Small myelinated...
