Anatomy MCQs - ANZCA Flashcards
At what level does the spinal cord end in the adult? A. S2 B. T12 C. L1 D. L5
Adult: spinal cord ends L1/2
The SVC is formed by what 2 structures?
A. Brachiocephalic trunk and azygous vein.
B. Right and left brachiocephalic vein
C. Internal jugular vein and right subclavian vein.
D. ?
B
Epidural space does not contain the following A. Epidural fat B. Epidural veins C. Posterior spinal artery D. Anterior spinal artery E. Lymph vessels
As the vertebral column grows, it leaves behind the spinal cord so that by adulthood the cord ends at the lower border of L1 (although this can vary by one vertebra). The dural sac generally ends at the lower border of S2 below which it continues as the filum terminale, a structure clearly and frequently seen with spinal endoscopy. The dural sac contains the anterior and posterior spinal nerve roots, collectively know as the cauda equina. Spinal nerves
The epidural space contains fat, the dural sac, spinal nerves, blood vessels and connective tissue
Applied epidural anatomy

so no lymph nodes
I mean lymph vessel
D - anterior spinal artery is NOT in the epidural space, it is found in the pia mater along the anterior median fissure of the spinal cord. Epidural space contains lymph vessels/drainage
- agree with D , HLF
NP04 [Sept13] The following are correct dermatome distribution except A. T4/5 nipple line B. T10 umbilicus C. T8 Ribs D. T2/C4/C5 shoulder E. T12 Buttocks and suprapubic area
Buttocks: Lumbar and sacral (L2-3, S1-4) Groin: T12-L1
NP05 -15A
Bronchial arteries:
A. Provide a low pressure flow to lung parenchyma
B. Provide blood to all bronchioles down to the respiratory bronchioles
C. Are branches from the intercostal arteries
D. Provide blood supply to both visceral and parietal pleura
E. Provide supply to some lung parenchyma
A - F - bronchial artery part of systemic circulation, thus high pressure , compared to pulmonary artery = pulmonary circulation
B - T
C - F ? - left BA thoracic aorta, right BA from intercostal arteries
D - F - visceral pleura only
E - F - lung parenchyma = portion of lung involved in gas transfer, the alveoli, alveolar ducts, respiratory bronchioles
-HLF
NP06 14B Which of the following are branches of the aorta A. coronary artery B. brachiocephalic C. right carotid D. right subclavian E. inferior thyroid
Both coronary arteries arise from the aortic root.
The 3 branches from the aortic arch are:
Brachiocephalic artery (on the right)
Left common carotid artery
Left subclavian artery
Thus in the remembered version above both A and B are correct. As only one answer is required, the MCQ has not been remembered accurately. Perhaps the MCQ was: “Which ONE of the following is a branch of the aortic arch?” -> Answer B.
Spinal arteries
A. There is NO anastomosis between the anterior and posterior spinal arteries
B. Arteries enter the cord at T10-L1
C. Arteries enter via the lamina foramina
D. Anterior spinal artery travels on the right side
E. ?
A - true
A is incorrect. Arterial vasocorona anaestamoses the two spinal arteries[1]. I don’t know which is the correct answer though. The artery of Adamkiewicz enters around T10-L1 ?B the correct answer.
Alt version:
Regarding spinal cord blood flow:
A. Anterior and posterior spinal arteries do NOT anastomose in the spinal cord
B. Anterior spinal artery enters at T2-L1
C. Anterior spinal artery is derived from the right side
D. Arteries enter from the laminae forminae
E. ?
A - true
A is incorrect. Arterial vasocorona anaestamoses the two spinal arteries[1]. I don’t know which is the correct answer though. The artery of Adamkiewicz enters around T10-L1 ?B the correct answer.
What is the posterior boundary of the epidural space A. ? B. ? C. ? D. ? E. ?
Unknown
NP09 -Aug15 Axillary nerve block. On incision, patient complains of pain at antero-lateral aspect of forearm. What nerve has been missed? A. medial B. ulnar C. axillary D. musculocutaneous E. radial
D
