MODEL MCQ’S IN ANATOMY

INTRODUCTION

Please keep in mind the following tips when dealing with MCQ’s.

INTRODUCTION

• Answer all questions. Write your index number on this paper and on the answer paper. Do not remove this paper from the examination hall.

• These scripts are read by a machine. • Mark clearly and firmly. Soft or small

marks are not recognized by the machine. Cover the circle. Do not cover a large area out side the circle.

INTRODUCTION

• Write the name of the examination, subject and date in the space provided.

• Mark the index number in the box and write the index number in digits above the box.

plexus. b.F- Obviously not. How can it be superficial if it lies deep

to the deep fascia? (Use your common sense.) c.F- Since they are not under any wear and tear it has a

simple squamous epithelium, just like in capillaries. d.F- Vessels which carry lymph node to a node are afferent

vessels and away from a LN are efferent vv. e.F- TD drains the whole lymphatic field below the

diaphrapm and the left half of the lymphatics above it.

that the cranial nerves have the following central connection,

CN XII to IX - from the medulla. CN VIII to V - from the pons. CN IV & III - from the midbrain.

Question 4

inheritance.b. Increased maternal age : new single gene

mutations in children.c. Trisomy 21 : increased risk of congenital heart

disease.d. Erythrocytes : metaphase spreads for

b. c. Most Downs syndrome children suffer from

congenital heart disease.d. e.

FORMAT-QUESTION 5&6

• Some questions are based on a list of organs. Understand the use of the words all,none,only.

QUSTION 5

5. Read this list of arteries in the abdomen.A - coeliac axis B - superior mesenteric C -inferior mesentericOf these,

(a) None supply the derivatives of the foregut.(b) All supply the colon.(c) The appendix is supplied by B.(d) Only B supplies the small bowel.(e) Only A supplies the stomach.

QUESTION 5 - EXPLANATION

a.F- Coeliac axis is the artery of the foregut.b.F- Not the coeliac axis.c.T- because it is part of the mid gut.d.F- Duodenum is supplied by both the coeliac

axis and superior mesenteric arteries.e.T- Since stomach is a part of the foregut.

QUESTION 6

6. Read this list of veins in the thorax.A - azygos B - hemiazygos C- internal

thoracic D - accessory hemiazygosOf these veins

a.D drains in to A.b.B drains in to D.c.blood in C does not get in to A.d.all drain intercostal spaces.e.none drain the alveolar tissue.

QUESTION 6 - EXPLANATION

a.T-Both hemiazygos and accessory hemiazygos veins drain in to azygos vein.

b.Fc.T-Internal thoracic veins drain in to Brachiocephalic

veins.d.Te.T-Blood from alveolar tissue drain via pulmonary

veins.

FORMAT - QUESTION 7&8

• Questions based on a clinical situation but needing basic anatomical knowledge to answer.

• Remember it is the basic anatomical principle that is being questioned and not the clinical condition.

phalanx of the index finger completely cut(severed) through the distal interphalangeal jointspace. The doctor attending to his injuries willexpect to find

a. two divided tendons on the flexor aspect. b.four digital arteries bleeding.c.the pain sensation to be transmitted throughthe median nerve.d.the bone marrow to be exposed.e.the cut digital nerves to be clearly visible.

QUESTION7-EXPLANATION

a.F-Only the tendon of flexor digitorum profundus insert in to the flexor aspect of distal phalanx.

b.T-In each fingers there are four digital arteries.c.T-Lateral three and half fingers are supplied by

median nerve.d.F-The finger has divided through distal

interphalangeal joint.e.F-The distal digital nerves are small terminal branches

of cutaneaus nerves.

a. paralysis of adductor pollicisb. an inability to spread out the fingers.c. sensory loss over the dorsum of the hand.d. Hyperextension of the metacarpophalangeal andextension of the interphalangeal joints of ring andlittle fingers.e. Sensory loss over the tip of the little finger.

QUESTION 8-EXPLANATIONa.T-Adductor pollicis muscle is supplied by the deep branch

of ulnar nerve.b.T-This is the action of the Dorsal interossei muscles which

are supplied by Deep branch of ulnar nerve.c.F-The medial third of the back of the hand is supplied by

the dorsal branch of ulnar nerve.d.F-Paralysis of the intrinsic muscles of the hand cause to

extension of metacarpophalangeal joints and flexon of the interphalangeal joints due to unopposed action of long flexors and extensors of the hand.

e.F-This area is supplied by palmar digital branches of ulnar nerve.
