Anatomy Workshop Flashcards
What are letters E and F?
E = falciform ligament
F = ligamentum teres (round ligament)
What is this?
Lesser trochanter of femur
What are 5 and 13?
5 = intertrochanteric crest
13 = intertrochanteric line
What is this?
Bicipital groove of humerus
What is this?
Ulnar styloid
Which is the common fracture site of the clavicle?
Middle 1/3
Fracture of surgical neck of humerus may result in which nerve injury?
Axillary
Fracture of humerus mid-shaft may result in which nerve injury?
radial nerve
Supra-condylar fracture of the humerus may result in which nerve injury?
Ulnar nerve
Which nerve may be injured in distal humerus fracture?
Uncommon
In which direction does the hip tend to dislocate?
Posterior
Which nerve is most likely to be damaged in posterior hip dislocation?
Sciatic
Which structures arise from under the auricles?
Left and right coronary arteries
Name the great vessels from right to left anteriorly.
SVC, aorta, pulmonary trunk
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?
Transverse pericardial sinus – it allows cardiac surgeons to identify/clamp the ascending aorta/pulmonary trunk during surgery.
Name all of the vasculature.
Which artery is usually involved in an anterior infarction?
LAD
Which artery is usually involved in an inferior infarction?
right coronary artery (80% of time), circumflex artery (20% of time)
Which two major arteries supply blood to the brain?
Internal carotid & vertebral arteries
Which foramen does the vertebral artery pas through?
Foramen magnum
Which foramen does the internal carotid artery pass through?
Carotid canal
What are 10, 13, 16 and 17?
10 = superior cerebellar
13 = anterior inferior cerebellar artery
16 = posterior inferior cerebellar artery
17 = anterior spinal artery
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.
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.
Which nodes are shown by 2-4?
- Bronchopulmonary (Hilar)
- Superior Tracheobronchial
- Inferior Tracheobronchial
Hilar nodes are also called…
Bronchopulmonary nodes
Where does lymph from the parietal pleura drain to?
Body wall noes - mediastinal, thoracic, intercostal
. Why do runners bend over and hold on to their knees at the end of a race?
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
