Term
what is in the RUQ, LUQ, RLQ, and LLQ?
Definition
RUQ - right lobe of liver, gallbladder, pancreas head
LUQ - left lobe of liver, spleen, stomach
RLQ - cecum, appendix, ileum
LLQ - sigmoid colon
Term
what are the four fascia layers of the abdominal area?
Definition
Camper's fascia - fatty layer
Scarpa's fascia - membranous layer
Extraperitoneal fascia
Transversalis fascia
Term
what are the four abdominal muscles in order?
Definition
external oblique, internal oblique, and transverse abdominal.
rectus abdominis
Term
what are the four abdominal muscles in order?
Definition
external oblique, internal oblique, and transverse abdominis.
rectus abdominis
Term
where does the inguinal ligament run?
Definition
it's the lower border of the external oblique aponeurosis that runs from the anterior superior iliac spine and the public tubercle
Term
what are the two ligaments associated with the inguinal ligament?
Definition
lacunar - attaches to pecten pubis
pectineal - additional fibers from the lacunar
Term
what is the center line between the rectus abdominis muscles called?
Definition
linea alba
Term
what line does the posterior layer of the rectus sheath end at?
Definition
arcuate line
at this point, it just becomes transversalis fascia downward
Term
what are the two layers just below the transversus abdominis?
Definition
transversalis fascia and than parietal peritoneum.
also extraperitoneal fascia is sometimes present in between the two.
Term
what innervates the anterior abdominal wall?
Definition
ventral rami of T7-12(intercostal and subcostal nerves) and L1 (ilioinguinal nerve).
give off lateral and anterior cutaneous branches.
Term
what is the arterial supply of the superior anterior abdominal wall?
Definition
internal thoracic artery --> musculophrenic and superior epigastric artery
Term
what is the arterial supply of the inferior anterior abdominal wall?
Definition
superficial epigastric artery and superficial circumflex iliac artery.
Deep - inferior epigastric artery and deep circumflex iliac artery.
Term
gonads descend through what outpouching? what week? what guides this process?
what ends up surrounding the gonads?
males/females bring what along?
Definition
week 7 - processus vaginalis
guided by gubernaculum.
the internal oblique muscle, external oblique aponeurosis and the transversalis fascia end up around the gonads.
spermatic cord and ovaries/round ligament of the uterus are brought along.
Term
what is the conjoint tendon?
Definition
the combined insertion of the transversus abdominis and internal oblique that helps form medial part of the posterior side of the inguinal canal.
AKA the inguinal falx
Term
what layer covers the spermatic cord or the round ligament of the uterus?
Definition
internal spermatic fascia made from the transversalis fascia
Term
what is in the inguinal canal in both men and women?
Definition
ilioinguinal nerve
Term
what is in the spermatic cord? (5)
Definition
ductus (vas) deferens (and artery)
testicular artery
pampiniform plexus of veins
genital branch of the genitofemoral nerve
cremasteric artery and vein
Term
what three layers cover the spermatic cord?
Definition
internal spermatic fascia, cremasteric fascia, external spermatic fascia
Term
what is the shell of the testes?
Definition
tunica albuginea
Term
what are the parietal and visceral layers covering the testis? (one thing)
Definition
tunica vaginalis
Term
what is a hydrocele?
Definition
peritoneal fluid in a persistent processus vaginalis
can be on cord or in epididymis
Term
what is an indirect inguinal hernia?
Definition
congenital, protrusion through inguinal canal (deep and superficial) pulling along parietal peritoneum and viscera.
originate lateral to epigastric vessels.
Term
what is a direct inguinal hernia?
Definition
acquired, parietal peritoneum and viscera protrude through weak area of posterior wall of the inguinal canal (not in the scrotum).
originate medial to epigastric vessels.
