Exam 3 Review Session Flashcards
Ductus venosus in adults
Ligamentum venosus
Ductus venosus modification
Umbilical vein (liver to placenta) to caudal vena cava
Umbilical vein contains
Round ligament of the lver
Rectus sheath
Outer sheath
-Fusion of EAO and IAO apoenurosis
Inner sheath
-Traversus abdominis
Median ligament of the bladder
umbilicus and bladder
Vaginal ring formed by
parietal peritoneum
Deep inguinal ring boundaries
Cranially= internal abdominal oblique
Medially=rectus abdominis
Laterlly=external abdominal oblique
Muscle fibers of EAO, IAO, TA
EAO=caudoventrally
IAO=cranioventrally
TA=transverse
Blood vessels that supply abdominal wall
Dorsally
Cranial= phrenicoabdominal artery
Caudal=Deep circumflex iliac artery
Ventrally
Cranially= cranial superficial epigastric artery
Caudally=caudal superficial epigastric artery
Pancreas lobes
R=mesoduodenum
L=deep leaf of greater omentum
Extrinisic muscles
Attach limb to axial skeleton
Intrinisic muscles
Both origin and insertion are on thoracic limb skeleton
Combined aponeurosis of abdominal muscles that form mid ventral raphe make
Linea alba
Inguinal ligament interposed between
Vascular lacuna
Superficial inguinal ring
Superficial inguinal ring
A slit-like opening in aponeurosis of EAO
Space between deep inguinal ring and superficial inguinal ring
inguinal canal
Deep Inguinal ring
Triangular shape opening directly internal to superficial inguinal ring
Boundaries of deep inguinal ring
medially-lateral rectus abdominis
cranially-caudal edge of IAO
caudally-caudal edge of EAO (inguinal ligament)
Rectus sheath layers
External leaf
Aponeurosis of EAO fuses deeply near midline with aponeurosis of IAO
Internal leaf
Aponeuorsis of transversus abdominis
What is inside rectus sheath?
Rectus abdominus
2 Functions of the abdominal muscles
support viscera
abdominal press
Ansa subclavia
Loop from symp trunk around subclavian artery btw cervicothoracic and middle cervical ganglia.
Serous membrane in abdomen
Peritoneum
Azygous vein drains
Dorsal intercostal spaces
