8. Costal margin
9. Superior epigastric a
11. Posterior layer of rectus sheath
14. Arcuate line
15. Inferior Epigastric a
16. Inguinal ligament

Front 2

Describe Arcuate line.

Back 2

It is a horizontal line that demarcates the lower limit of the posterior layer of the rectus sheath. It is also where the inferior epigastric vessels perforate the rectus abdominus.

Front 3

Plate 207
Identify 33, 35, 36

Back 3

33. External intercostal m
35. Internal intercostal m
36. Anterior intercostal a., v., n.

Front 4

Plate 206
Identify: 2, 4, 5, 6 (name a & n), 7, 8, 10, 13, 15 (name m), 16 (name a & v), 17, 18, 19

Back 4

2. Clavicle
4. internal intercostal m
5. transversus thoracic m
6. intercostal a and n
7. musculophrenic a
8. superior epigastric a and v
10. rectus abdominis m
13. internal thoracic a and v
15. Innermost intercostal m
16. intercostal a and v
17. xiphoid process
18. linea alba and posterior layer of rectus sheath
19. transversus abdominis m

Front 5

Plate 269
Identify A, B, 2 (ignore a), 3 (not how it runs with jugular), 7, 15, 26 (there's a n, a, and v here)

Back 5

A. Horizonal fissure
B. Oblique fissure
2. Phrenic n (and scalenus anterior m
3. Vagus n (and internal jugular v)
7. Internal thoracic a
15. Cut edge of pericardium
26. Left phrenic n and left cardacophrenic a and v

Front 6

Describe the difference between perietal pleura and perietal peritoneum.

Back 6

Perietal pleura lines the thoracic cavity. Perietal peritoneum lines the abdominal cavity.

Front 7

What is the pubic symphysis?

Back 7

It is the midline cartilaginous joint (secondary cartilaginous) uniting the superior rami of the left and right pubic bones

Front 8

What is the pyramidalis m.

Back 8

It is a small triangular muscle anterior to the rectus abdominis and within the rectus sheath.

Front 9

What is the root of lung?

Back 9

A little above the middle of the mediastinal surface of each lung, and nearer its posterior than its anterior border, is its root, by which the lung is connected to the heart and the trachea.

Front 10

Review the boundaries of the inguinal canal (p43 lab man.) - work on post and sup - the rest you got.

Back 10

Deep: deep inguinal ring
Superficial: superficial inguinal ring
Anterior: aponeurosis of the external oblique muscle
Posterior: transversalis fascia, reinforced medially by the conjoint tendon.
Inferior (floor): Inguinal ligament
Superior (root): the arching fibers of the internal oblique and the transversus abdominis muscles
