Q

what is the midline of the body called

A

the linea alba

17
Q

From superficial to deep what are the layers of the abdominal wall

A

dermis, epidermis, superficial fascia/camper fascia (subcutaneus fat layer), deep fascia, external oblique, internal oblique, transverse oblique, extraperitoneal fat layer

18
Q

where and what are the tendinous intersections of the rectus abdominus

A

interspersed tendineous bands that create the compartments

19
Q

on which side (ventral or dorsal) is the rectus abdominus crossed by the aponeurosis

A

both

20
Q

what is the rectus sheath composition above the umbilicus

A

it has an anterior sheath and a posterior sheath.

aponeurosis of the externus = anterior

internus = divided between anterior and posterior

transverse = posterior

21
Q

what is the rectus sheath composition below the umbilicus

A

only one sheath, the anterior, because of this it is extra thick. however there is still a thin layer posterior that is made of the transversalis facia and peritoneum

22
Q

what are plicae

A

umbilical folds

23
Q

how are plicae formed and where are the structures located that form them

A

by the parietal peritoneum, they are located between the parietal peritoneum and the transversalis fascia
