Neurovascular pairing - naming

Nerves and arteries are frequently named together by the bones/regions with which they are
associated. The following are exceptions to this naming convention

2

Axilla/lateral thorax -neurovascular pairing - nerve and artery

Long thoracic n.
Lateral thoracic a.

3

Surgical neck of
humerus -neurovascular pairing - nerve and artery

Axillary n.
Posterior circumflex a.

4

Midshaft of humerus -neurovascular pairing - nerve and artery

Radial n.
Deep brachial a.

5

Distal humerus/
cubital fossa -neurovascular pairing - nerve and artery

Median n.
Brachial a.

6

Popliteal fossa -neurovascular pairing - nerve and artery

Tibial n.
Popliteal a.

7

Posterior to medial
malleolus -neurovascular pairing - nerve and artery

Tibial n.
Posterior tibial a.

8

radial nerve in midshaft of humerus is passing through

spiral groove

9

the cubital fossa is a

triangular hollow area that lies in front of the elbow joint

10

the popliteal fossa

is a shallow depression located at the back of the knee joint ( ιγνυακός βόθρος )

11

medial malleolus is

the medial surface of the lower extremity of tibia is prolonged downward to form a strong pyramidal process

12

lateral malleolus

the lower extremity of the fibula ( pyramidal form )

13

malleolus in greek

σφυρό

14

tarsal tunnel is found

along the inner leg posterior to medial malleolus

15

tarsal tunnel is found

along the inner leg posterior to the medial malleolus

16

Lumbosarcal radiculopathy - intervertebral discs direction ( why )

herniate posterolaterally due to the thin posterior longitudinal ligament and thicker anterior longitudinal ligament along the midline of the vertebral bodies

17

site of intramascular injection

choose superolateral gluteal quardant to avoid nerve injury

18

superior gluteal nerve innervates

1. medius gluteous
2. minimus gluteus
3. tensor fascia latae

19

presentation of proximal tibial nerve injury

foot everted at rest with loss of inversion and plantar fexion

20

• A patient fractures the midshaft of his humerus and damages his radial nerve. What artery was likely injured?

Deep brachial artery

21

• A patient lacerates his posterior tibial artery by dropping a table saw. What nerve will be impaired?

Tibial nerve (L4–S3)

22

• The median nerve runs what artery, through which fossa?

The brachial artery, the distal humerus/cubital fossa

23

• Which nerve and artery would you expect to see injured with a fracture at the surgical neck of the humerus?

Axillary nerve, the posterior circumflex artery

24

• A man is struck from behind by a thrown javelin; it lands in his popliteal fossa. What major nerve and artery are at risk of being damaged?

Tibial nerve, popliteal artery

25

• A patient suffers a fracture of the medial malleolus. What nerve and artery may be damaged secondary to this insult?

Tibial nerve, posterior tibial artery
