Q

Transversus abdominus

A

O: Internal surfaces of ribs 7-12 costal cartilages, thoracolumbar fascia, iliac crest, and connective tissue deep to inguinal ligament
I: Linea alba with aponeurosis of internal oblique, pubic crest, and pectin pubis via conjoin tendon
A: Compresses and supports abdominal viscera
I: Thoraco-abdominal nerves (anterior rami of T7-T11) and first Lumbar nerve (L1)

23
Q

Above arcuate line, internal oblique fascia

A

splits, contributing to both anterior sheath fusing with external oblique aponeurosis and posteriorly fusing with transversus abdominus

24
Q

Below arcuate line, internal oblique fascia

A

doesn’t split; all passes anteriorly to rectus
posterior wall is only transversalis fascia and parietal peritoneium
Weaker - prone to hernias

25
Q

Transversalis fascia

A

layer of fascia that lines internal abdominal wall and forms the deep inguinal ring

26
Q

Parietal peritoneum

A

Serous lining of peritoneum
Produces serous fluid that lubricates the abdominal organs
It is usually not fused tightly with the transversalis fascia - can contain fat stores
Inferior epigastric arteries and veins are located between transversalis fascia and parietal peritoneum
Innervated by somatic body wall nerves

27
Q

Falciform ligament

A

last remnant of ventral mesentery

28
Q

Round ligament

A

remnant of fetal umbilical vein (main O2 from placenta to fetus)

29
Q

Median umbilical fold

A

urachus (remnant of allantois, drains fetal bladder) and paraumbilical veins (can become enlarged and patent during portal hypertension)

30
Q

Medial umbilical folds

A

2 of these, on either side of median umbilical fold

Remnants of umbilical arteries (returns low O2 blood back to placenta)

31
Q

Lateral umbilical folds

A

2 of these

inferior epigastric arteries and veins

32
Q

Somatic innervation is from

A

ventral rami of spinal nerves (intercostal nerves) running from T7-L2
Intercostal nerves become thoracoabdominal nerves as they cross the costal cartilage

33
Q

Thoraco-abdominal nerves (T7-T11)

A

Continuation of lower intercostal nerves
Run between 2nd and 3rd layers of abdominal muscles; lateral and anterior cutaneous branches enter subcutaneous tissue
Innervate muscles of anterolateral wall and overlying skin

34
Q

Subcostal nerve (T12)

A

From Anterior ramus of L1 spinal nerve
Courses on inferior border of 12th rib, then onto subumbilical abdominal wall
Innervates muscles of anterolateral abdominal wall and overlying skin superior to iliac crest and inferior to umbilicus

35
Q

Iliohypogastric nerve (L1)

A

From anterior ramus of T12 spinal nerve
Pierces transversus abdominus muscle; branches pierce external oblique aponeurosis of most inferior abdominal wall
Innervates skin overlying iliac crest, upper inguinal and hypogastric regions; internal oblique and transversus abdominis

36
Q

Ilioinguinal nerve (L1)

A

from anterior ramus of L1 spinal nerve
Passes between 2nd and 3rd layer of abdominal muscles, then transverses inguinal canal
Innervates skin of scrotum or labia majus and mons pubis, and adjacent medial aspect of thigh; most inferior internal oblique and transversus abdominus

37
Q

Musculophrenic a.

A

From internal thoracic a.
Descends along costal margin
To abdominal wall of hypochondriac region, anterolateral, diaphragm

38
Q

Superior epigastric a.

A

From internal thoracic a.
Descends in rectus sheath deep to rectus abdominus
To Rectus abdominus and superior part of anterolateral wall

39
Q

Posterior intercostal a. (10th and 11th)

A

From Aorta
Continues beyond ribs to descend in abdominal wall between internal oblique and transversus abdominus
To lateral region of abdominal wall

40
Q

Subcostal a.

A

from Aorta
Continues beyond ribs to descend in abdominal wall between internal oblique and transversus abdominus
To lateral region of abdominal wall

41
Q

Inferior epigastric a.

A

From external iliac a.
Runs superiorly and enters rectus sheath, runs deep to rectus abdominus
To rectus abdominus and medial part of anterolateral abdominal wall

42
Q

Deep circumflex iliac a.

A

From external iliac a.
Runs on deep aspect of anterior abdominal wall, parallel to inguinal ligament
To iliacus muscle and inferior part of anterolateral abdominal wall

43
Q
