Outline 11: the abdomen Flashcards
What is the superior border of the abdomen
diaphragm
What is the inferior border of the abdomen
pelvic inlet
what is the anterior and lateral borders of the abdomen
muscle
basically a muscular wall with no bones
What is the posterior border of the abdomen
lumbar verterbrae
what are the contents of the abdomen
most of the unpaired (stomach, spleen, pancreas, intestines) and paired (kidneys, adrenal glands) viscera
What are the 4 major layers of fascia?
Superficial, Deep, Transversalis, and Peritoneum
What are the two types of Superficial fascia
Camper’s Fascia and Scarpa’s Fascia
What is Camper’s Fascia
The more superficial, outer layer of the superficial fascia and it is primarily adipose tissue
what is scarpa’s fascia
it is the more internal of the superficial fascia, It is under Camper’s fascia and it is more membranous,
What is the transversalis fascia analogous to
endothoracic fascia
Where is the transversalis fascia
interior to the deep fascia and lines the abdominal wall
What are the two layers of the peritoneum
Parietal and visceral
Where is the parietal peritoneum
it is the more superficial peritoneum and clings to the transversalis fascia
where is the visceral peritoneum
it is the more interior layer of the peritoneum and surround organs in different ways
What is analogous to the pleura of the lungs
the peritoneum
What are the four anterior muscles of the abdomen?
external abdominal oblique, internal abdominal oblique, transversus abdominus, and rectus abdominus
How is the external abdominal oblique analogous to the external intercostals?
inferomedial fibers
go from being muscular posteriorly to membranous anteriorly
where do the external abdominal obliques originate? insert?
Originate from lower ribs and insert at the external oblique aponeurosis and iliac crest
What is the linea alba
the line where the two external oblique aponeurosis sheets meet
what do the most inferior fibers of the external oblique aponeurosis form
the inguinal ligament
How is the internal abdominal oblique analogous to the internal intercostals
-superomedial fibers
go from being membranous posteriorly to being muscular anteriorly
What is the inguinal ligament
it is a specialization of the external abdominal obliques that connects the ASIS with the public tubercle
it forms the base of the iguinal canal
where does the internal abdominal oblique originate and insert
thoracolumbar aponeurosis and iliac crest to the ribs
what is the transversus abdominus
it is the deepest layer and has transversely oriented fibers
