When the EAO from its origin directly inserts into the iliac crest and the anterior superior iliac spine what is its direction
EAO originates from the lower 8 ribs and directly inserts on the iliac crest and the anterior superior iliac spine in a medioinferior direction.
What does the EAO become when it attaches to the xiphoid process, linea alba, pubic tubercle, and pubic crest
An aponeurosis
What forms the inguinal ligament
Inguinal ligament is formed by the aponeurosis of the EAO
What does the inguinal ligament attach to...
Inguinal ligament curls under and attaches to the thigh fascia
How does the inguinal ligament relate to the EAO
inguinal ligament is the lower free margin of the aponeurosis of the EAO
Dividing point between the anteriolateral wall of the abdomen and thigh
inguinal ligament
superficial inguinal ligament
opening like structure on the aponeurosis of the EAO
spermatic cord
present in males. it goes thru the superficial inguinal ring, thru the abdominal wall, and attaches to the testes
round ligament
in females. it goes thru the superficial inguinal ring and connects to the labia major.
what makes up the spermatic cord
3 layers form the pipe of the spermatic cord
1. external spermatic fascia
2. cremaster muscle and fascia
3. internal spermatic fascia
external spermatic fascia
comes from aponeurosis of EAO
cremaster muscle and fascia
comes from aponeurosis of IAO. it fxns in the reflex of the testes so that they are pulled toward the body in a cold environment
internal spermatic fascia
comes from transversalis fascia
Origin of IAO
1. Thraco-lumbar fascia
2. Iliac crest
3. Inguinal ligament
Direction of travel of IAO fibers
superiorly and medially from the origin (or inferior laterally)
Insertion of IAO
1. Lower 3-4 ribs
2. Aponeurosis attached to the costal margin
3. Pubic crest
4. Xiphoid process
5. linea alba
Origin of TA
1. Thoraco-lumbar fascia
2. Iliac crest
3. Inguinal ligament
4. Cartilage of lower 6 ribs
Direction of travel of TA fibers
horizontal or transverse
Insertion of TA
1. Xiphoid process
2. Linea alba
3. Pubic crest
What covers the rectus abdominus
rectus sheath
Rectus sheath is located underneath what
subcutaneous tissue
Aponeurosis of EAO, IAO, and TA contribute to the anterior and posterior rectus sheath. T/F
True
Rectus sheath extends from what to what
from xiphoid process and adjacent costal cartilages to the pubic bone
Origin of rectus abdominus
Pubic crest
Insertion of rectus abdominus
Superiorly, it inserts with the xiphoid process and cartilages of ribs 5-7
What are tendinous intersections and how do they affect rectus abdominus
Tendinous Intersections are CT bands that divide the rectus abdominus into 3-5 areas.
Contents of rectus sheath
1. Rectus abdominus
2. inferior and superior epigastric arteries
3. Thoracoabdominal nerve
4. Subcostal nerve
Where is the arcuate line of rectus sheath located and what is its function
Location: In the posterior wall of rectus sheath halfway between the umbilicus and pubic bone
Function: Dividing line where the posterior wall of rectus sheath changes in structure
Describe transversalis fascia above arcuate line
It is anterior to or above the extraperitoneal CT/fascia. It is posterior or below the posterior wall of rectus sheath. In other words, it is deep to the rectus abdominus muscle
Describe transversalis fascia below arcuate line
It is anterior to or above the extraperitoneal CT/fascia. It is adjacent to the rectus abdominus muscle.
Describe transversalis fascia in the anteriolateral wall
It is anterior to or above the extraperitoneal CT/fascia. It is posterior to or below the transversus abdominus muscle
Describe the anterior layer of rectus sheath above the arcuate line
Consists of aponeurosis of EAO and aponeurosis of anterior lamina of the IAO

Describe the anterior layer of rectus sheath below the arcuate line
Consists of aponeurosis of EAO, IAO, and TA
Describe the posterior layer of rectus sheath below the arcuate line
Does not contain any aponeurosis of abdominal muscles and thus the rectus abdominus muscle rests directly on the transversalis fascia

False
Below the arcuate line there is a posterior layer. T/F?
False
