Q

Abdominal Layers

A
  1. Skin
  2. Superficial fascia
  3. Abdominal muscles
  4. Deep fasciA
  5. Abdominal lining
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
Q

External oblique origin and insertion

A

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
Q

Innervation of external oblique

A

ventral rami of T7-12 (12 is subcostal) and
iliohypogastric nerves from L1 nerve root

27
Q

External oblique action

A

• bilaterally , aids with trunk flexion
• unilaterally, lateral bending in L-Spine and lateral
rotation of trunk.

28
Q

Internal oblique o and I

A

• 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
Q

Innervation internal oblique

A

ventral rami of T7-12 (12 is subcostal),
iliohypogastric and ilioinguinal nerves (from L1 nerve root)

30
Q

Action internal oblique

A

• bilaterally, aids with trunk flexion
• unilaterally , lateral side bending and lateral rotation
of trunk.
• Works in conjunction with External Oblique

31
Q

Trans versus abdominus origin

A

• 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
Q

Trans versus abdominus insertion

A

Linea alba
• Contributes to
formation or posterior rectus sheath

33
Q

Trans versus abdominus innervation

A

Ventral rami
of T7-T12 and all of L1

34
Q

Action of trans versus abdominus

A

Compression of
Abdomen
• May play vital role in lumbar stabilization
• WHY?

35
Q

Recuts abdominus origin and insertion

A

• Origin: Pubic crest and Pubic tubercle
• Insertion: Cartilage of ribs 5-7

36
Q

Rectus abdominus innervation

A

ventral rami of t7-t12

37
Q

Action rectus abdominus

A

Bilaterally à aids with trunk flexion
• Approximates ribs to pelvis
• Increase intrabdominal pressure
• Aid in defecation, urination, childbirth,
and a general lumbar stabilizer

38
Q

Abdomen function

A

• 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
Q

protrusion of
an organ or part of an
organ that passes through
connective tissue or the
wall of a cavity which is
normally closed.

A

Hernia

40
Q

common after large amounts of
weight loss and post partum

A

Abdominal hernia

41
Q

AbdominAL hernias

A

Epigastric, umbilical, spligelian

42
Q

follow femoral artery
and vein (do not go through inguinal canal)

A

Femoral hernias

43
Q

• 90% of all hernias • Mainly occur in males

A

Inguinal hernias

44
Q

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)

A

Inguinal hernias
