fibrous band that connects the two rectus abdominis muscles
linea alba
The ___ muscles form the lateral sides of the anterior abdominal wall
oblique
The ____ muscle is most superior and lies anterior to the internal oblique muscle.
external oblique
The ___ muscles lie anterior to the transversus abdominis/transversalis muscle
internal oblique
vertical fibrous band at the lateral edge of the rectus sheath
linea semilunaris
The linea sumilunaris is also known as the
spigelian fascia
____ lies deep to abdominal wall muscles and lines entire abdominal wal
Transversalis fascia
The transversalis facia is separated from parietal peritoneum by a layer of ____
extraperitoneal fat
Ultrasound evaluation of the abdominal wall should include application of the ___ and imaging the patient in a ___ position
valsalva maneuver
standing
blood collection between the layers of the rectus sheath
rectus sheath hematoma
A rectus sheath hematoma is a common complication seen with:
antiocoagulant therapy
a horizontal line that demarcates the lower limit of the posterior layer of the rectus sheath
arcuate line
The posterior rectus sheath ends at the level of the:
arcuate line
The arcuate line is usually located between the ___ and the ___
umbilicus
symphysis pubis
location where the inferior epigastric vessels perforate the rectus abdominis muscles
arcuate line
most common cause of rectus sheath formation
injury to the inferior epigastric artery
____ the arcuate line, hematomas are confined within the sheath
above
___ the arcuate line, the blood is not confined within the sheath and can extend into the ____
Below
Space of Retzius
The ___ stops the hematoma from extending across the midline above the arcuate line
linea alba
Sonographic appearance of rectus sheath hematoma
varies with blood/thrombus age
usually fills the space of the space it occupies
good through transmission with early hematomas
increased distance between the rectus abdominis muscles caused by weakness in the anterior abdominal wall
diastasis recti
The ___ is normally a narrow fibrous band in the midline abdomen that separates the two rectus abdominis muscles
linea alba
____ and ____ cause diastasis recti
muscle weakness
thinning/stretching of the linea alba
The distance between the two rectus abdominis muscles can increases with ___, ___, and in ___
pregnancy
obesity
newborns
