1. Upward movement of the thyroid gland is
prevented due to?
a) Berry ligament
b) Pretracheal fascia
c) Sternothyroid muscle
d) Thyrohyoid membrane
Correct Answer - B
Ans: B. Pretracheal fascia
The thyroid gland is covered by a thin fibrous capsule, which has an
inner and an outer layer. The inner layer extrudes into the gland and
forms the septum that divides the thyroid tissue into microscopic
lobules.
The outer layer is continuous with the pretracheal fascia, attaching
the gland to the cricoid and thyroid cartilages via a thickening of the
fascia to form the posterior suspensory ligament of the thyroid gland
also known as Berry's ligament. This causes the thyroid to move up
and down with the movement of these cartilages when swallowing
occurs.

,2. The reason for the long left recurrent
laryngeal nerve is due to the persistence of
which arch artery?
a) 3rd arch
b) 4th arch
c) 5th arch
d) 2nd arch
Correct Answer - B

,3. Ligation of the hepatic artery will impair
blood supply in
a) Right gastric and Right gastroepiploic artery
b) Right gastric and Left gastric artery
c) Right gastroepiploic and short gastric vessels
d) Right gastric and short gastric vessels
Correct Answer - A
Ans: A. Right gastric and Right gastroepiploic artery
The right gastric artery is a branch of the common hepatic artery
The right gastroepiploic artery is a branch of the gastroduodenal
artery which is a branch of the common hepatic artery
The left gastric artery is a branch of the celiac trunk
Short gastric vessels arise from the splenic artery

, 4. Wolffian duct remnant in female is
a) Pouch of Douglas
b) Uterovesical pouch
c) Gartner’s cyst
d) Broad ligament
Correct Answer - C
Ans: C. Gartner’s cyst
Gartner’s cysts, sometimes incorrectly referred to as vaginal
inclusion cysts, are the most common benign cystic lesions of the
vagina.
They represent embryological remnants of the caudal end of the
mesonephric( Wolffian) duct.
Gartner’s ducts are found in about 25% of adult women. Almost one
percent of these ducts evolve into Gartner’s duct cyst.
