20
Q

Abdominal lining

A

Parietal peritoneum

21
Q

Superficial fascia

A

Superficially (fatty) = campers
Deeper (membranous)= scarpas

22
Q

Deep fascia =

A

Transversalis

23
Q

Lies between the transverse
abdominis and the extraperitoneal fascia

A

Transversalis fascia

24
Q

Single cell thick serous
membrane lining the abdominal cavity and its viscera

A

Peritoneum

25
External oblique origin and insertion
O: lower eight ribs I: Membranous portion inserts on the iliac crest and the tendonous portion inserts into the linea alba • Superolateral to inferomedial • Orientation of your fingers when your hands are in front pockets
26
Innervation of external oblique
ventral rami of T7-12 (12 is subcostal) and iliohypogastric nerves from L1 nerve root
27
External oblique action
• bilaterally , aids with trunk flexion • unilaterally, lateral bending in L-Spine and lateral rotation of trunk.
28
Internal oblique o and I
• Origin: Anterior 2/3 of iliac crest and lateral 2/3 of inguinal ligament, and thoracolumbar fascia posteriorly • Insertion: Inferior border of 10-12th ribs, the cartilage of ribs 9-10 and linea alba • Inferolateral to superomedial • Same orientation of fingers over heart
29
Innervation internal oblique
ventral rami of T7-12 (12 is subcostal), iliohypogastric and ilioinguinal nerves (from L1 nerve root)
30
Action internal oblique
• bilaterally, aids with trunk flexion • unilaterally , lateral side bending and lateral rotation of trunk. • Works in conjunction with External Oblique
31
Trans versus abdominus origin
• Costal: Inner surface of lower 6 costal cartilages (interdigitates with diaphragm) • Lumbar: Lumbar vertebrae by thoracolumbar fascia • Pelvic: inner lip of iliac crest and lateral 1/3 of inguinal ligament
32
Trans versus abdominus insertion
Linea alba • Contributes to formation or posterior rectus sheath
33
Trans versus abdominus innervation
Ventral rami of T7-T12 and all of L1
34
Action of trans versus abdominus
Compression of Abdomen • May play vital role in lumbar stabilization • WHY?
35
Recuts abdominus origin and insertion
• Origin: Pubic crest and Pubic tubercle • Insertion: Cartilage of ribs 5-7
36
Rectus abdominus innervation
ventral rami of t7-t12
37
Action rectus abdominus
Bilaterally à aids with trunk flexion • Approximates ribs to pelvis • Increase intrabdominal pressure • Aid in defecation, urination, childbirth, and a general lumbar stabilizer
38
Abdomen function
• Protects and supports viscera • Aids in micturition, defecation, respiration, yelling, coughing, sneezing, vomiting, and childbirth • Also aids in trunk and spine stability to maintain posture. • How? • Clinically LBP
39
protrusion of an organ or part of an organ that passes through connective tissue or the wall of a cavity which is normally closed.
Hernia
40
common after large amounts of weight loss and post partum
Abdominal hernia
41
AbdominAL hernias
Epigastric, umbilical, spligelian
42
follow femoral artery and vein (do not go through inguinal canal)
Femoral hernias
43
• 90% of all hernias • Mainly occur in males
Inguinal hernias
44
Direct – into inguinal canal through the wall (pictured) • Weakness of posterior abdominal wall of the inguinal canal • Indirect – through the deep inguinal ring • Can be weakness but usually Congenital abnormal persistence of processus vaginalis (extension of the peritoneum through inguinal canal)
Inguinal hernias
