Q

Transversus abdominus

Study These Flashcards
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

Study These Flashcards
A

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

24
Below arcuate line, internal oblique fascia
doesn't split; all passes anteriorly to rectus posterior wall is only transversalis fascia and parietal peritoneium Weaker - prone to hernias
25
Transversalis fascia
layer of fascia that lines internal abdominal wall and forms the deep inguinal ring
26
Parietal peritoneum
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
Falciform ligament
last remnant of ventral mesentery
28
Round ligament
remnant of fetal umbilical vein (main O2 from placenta to fetus)
29
Median umbilical fold
urachus (remnant of allantois, drains fetal bladder) and paraumbilical veins (can become enlarged and patent during portal hypertension)
30
Medial umbilical folds
2 of these, on either side of median umbilical fold | Remnants of umbilical arteries (returns low O2 blood back to placenta)
31
Lateral umbilical folds
2 of these | inferior epigastric arteries and veins
32
Somatic innervation is from
ventral rami of spinal nerves (intercostal nerves) running from T7-L2 Intercostal nerves become thoracoabdominal nerves as they cross the costal cartilage
33
Thoraco-abdominal nerves (T7-T11)
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
Subcostal nerve (T12)
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
Iliohypogastric nerve (L1)
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
Ilioinguinal nerve (L1)
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
Musculophrenic a.
From internal thoracic a. Descends along costal margin To abdominal wall of hypochondriac region, anterolateral, diaphragm
38
Superior epigastric a.
From internal thoracic a. Descends in rectus sheath deep to rectus abdominus To Rectus abdominus and superior part of anterolateral wall
39
Posterior intercostal a. (10th and 11th)
From Aorta Continues beyond ribs to descend in abdominal wall between internal oblique and transversus abdominus To lateral region of abdominal wall
40
Subcostal a.
from Aorta Continues beyond ribs to descend in abdominal wall between internal oblique and transversus abdominus To lateral region of abdominal wall
41
Inferior epigastric 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
Deep circumflex iliac 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
Superficial circumflex iliac a.
From femoral a. Runs in superficial fascia long inguinal ligament To superficial abdominal wall of inguinal region and adjacent anterior thigh
44
Superficial epigastric a.
From femoral a. Runs in superficial fascia towards umbilicus To subcutaneous tissue and skin over pubic and inferior umbilical region
45
Anastomoses between aorta
Posterior intercostals Posterior subcostals Lumbar arteries
46
Anastomoses between internal thoracic a.
Superior epigastric | Musculophrenic - anterior intercostals
47
Anastomoses between external iliac
Inferior epigastric | Deep circumflex iliac
48
Anastomoses between Femoral
Superficial epigastric | Superficial circumflex iliac
49
Where would you make an incision for an appendicitis
Gridiron (through muscle layers at McBurney point)
50
Where would you make an incision for gallbladder
Subcostal (below costal cartilage)
51
Where would you make an incision for transverse colon or small intestines?
Median (on linea alba)
52
Where would you make an incision for ovaries
Transverse
53
Where would you make an incision for a hysterectomy?
Suprapubic
54
If have an illness above Transumbilical plane will have huge lymph nodes in
Armpits (axillary lymph nodes)
55
If have an illness below transumbilical plane will have huge lymph nodes in
Superficial inguinal lymph nodes
