Q 6
c
C1 goes above 1st Cx vert & so on till C7
C8 goes below C7 & T1 below 1st T vert. & soon
so L4 goes below 4th L vert.
& nerves go thru sup part of intervert foramen
that is why a disc protusion at L4 L5 level will not compress L4 nerve but will compress L5

6.) The correct answer is: C)Below the pedicle of L4 and at the top of the intervertebral foramen

Remember, in the lumbar region, spinal nerves exit below the vertebra with the same number. So, the L4 nerve exits below the L4 vertebra. The spinal nerves also exit at the top of the intervertebral foramen.

7.)An 8-year-old boy is found to have a mid-line tumor of the thymus gland that is impinging posteriorly on a blood vessel. The affected vessel is most likely the:
left brachiocephalic vein
left pulmonary vein
left bronchial vein
right pulmonary artery
right superior intercostal vein

8.)A sick person, lying supine in bed, aspirates (breathes in) some fluid into her lungs while swallowing. It would most likely end up in which of the following bronchopulmonary segments?

1]anterior segmental bronchus of right superior lobe
2]medial segmental bronchus of right middle lobe
3] superior segmental bronchus of right inferior lobe
4]medial basal segmental bronchus of left inferior lobe
5]inferior segmental bronchus of lingular lobe

9.)A 19-year-old female presented with fever, myalgia,
sore throat, and mild erythematous rash over her abdomen
and thighs. These symptoms abated in a month, and she
remained healthy until 8 years later, when decreased visual
acuity and pain in her right eye led to a finding of cyto-
megalovirus retinitis on funduscopy. Assuming that her ini-
tial illness and the ocular problem are a part of the same
disease process, which of the following laboratory test
findings is most likely to be found in this patient after her
ocular problems began to appear?
A) Antinuclear antibody titer of 1:1024
B) Total serum globulin level of 650 mg/dL
C) Positive HLA-B27 antigen
D) Anticentromere antibody titer of 1:512
E) CD4 lymphocyte count of 102//xL

10.)

A 39-year-old female has fingers that are tapered and
clawlike, with decreased motion at the small joints. The
microscopic appearance of the skin is shown in the figure.
She also has diffuse interstitial fibrosis of the lungs, with
pulmonary hypertension and cot pulmonale. Which of the
following dermal inflammatory cells is considered the most
likely initiator of the process that results in her skin dis-
ease?
A) CD4 lymphocyte
B) Macrophage
C) Mast cell
D) Neutrophil
E) NK cell

11.)

A 3-month-old boy presented with recurrent infec-
tions. The infectious agents included Candida albicans, P.
carinii, Pseudomonas aeruginosa, and cytomegalovirus.
Despite intensive treatment with antibiotics and antifungal
drugs, he died at the age of 5 months. At autopsy, lymph
nodes were found to be small with very few lymphocytes
and no germinal centers. The thymus was hypoplastic, as
were the Peyer patches and tonsils. There is a history of
other males in the family who presented in a similar man-
net. The most common cause for this form of immunodefi-
ciency is

A) Maternal HIV infection
B) Loss of chromosome 22q 11
C) Mutation in the common y chain of cytokine recep-
tors
D) Mutation in the Bruton tyrosine kinase (btk) gene
E) Mutation in CD40 ligand

11.)
An epidemiologist decided to conduct a cross-sectional study to asseess the associated risk factors for a given disease.What statistical analysis does he need to prefer?
a)Attributable risk
b)Odd's ratio
c)chi square
d)t-test
e)Relative risk
