Answer 8

radial nerve

Question 9

Question 11

In which direction does the hip tend to dislocate?

Posterior

Question 12

Which nerve is most likely to be damaged in posterior hip dislocation?

Answer 12

Sciatic

Question 13

Which structures arise from under the auricles?

Answer 13

Left and right coronary arteries

Question 14

Name the great vessels from right to left anteriorly.

Answer 14

SVC, aorta, pulmonary trunk

Question 15

Name the ‘space’ posterior to the pulmonary trunk and ascending aorta and anterior to the superior vena cava. What is the clinical significance of this space?

Answer 19

Internal carotid & vertebral arteries

Question 20

Which foramen does the vertebral artery pas through?

Answer 20

Foramen magnum

Question 21

Answer 21

Carotid canal

Question 22

What are 10, 13, 16 and 17?

Answer 22

10 = superior cerebellar

13 = anterior inferior cerebellar artery

16 = posterior inferior cerebellar artery

17 = anterior spinal artery

Question 23

Using your knowledge of anatomy and with the aid of a diagram, explain why patients with a lower motor neurone lesion of the facial nerve (CN VII) are unable to show their teeth (smile) and unable to raise their eyebrows, whereas patients with an upper motor neurone lesion are unable to show their teeth, but still able to raise their eyebrows.

Answer 23

Muscles of forehead (frontalis) receive bilateral corticonuclear innervation from facial _nerve; therefore muscles used to raise eyebrows still function after UMNL. Muscles used for smiling receive only contralateral facial nerve innervation, so are affected.

Question 24

Which nodes are shown by 2-4?

Answer 24

2. Bronchopulmonary (Hilar)
3. Superior Tracheobronchial
4. Inferior Tracheobronchial

Question 25

Hilar nodes are also called…

Answer 25

Bronchopulmonary nodes

Question 26

Where does lymph from the parietal pleura drain to?

Answer 26

Body wall noes - mediastinal, thoracic, intercostal

Question 27

. Why do runners bend over and hold on to their knees at the end of a race?

Answer 27

Out of breath; hold on to knees to fix scapula; accessory muscles of respiration can then be recruited to raise ribs: pectoralis major, pectoralis minor, serratus anterior
