What Lies Beneath (the Skin)
This dermatome supplies the skin at the level of the umbilicus.
What is T10?
This artery is a continuation of the internal thoracic artery and enters the rectus sheath.
What is the superior epigastric artery?
This nerve (L1) provides sensation to the skin over the pubic region and medial thigh
What is the ilioinguinal nerve?
This structure passes through the deep inguinal ring in males.
What is the spermatic cord?
These two areas/organs are supplied by the ileocolic artery.
What is the appendix & cecum?
This structure is deficient posterior to the rectus abdominis below the arcuate line.
What is the posterior rectus sheath?
The inferior epigastric artery arises from this vessel.
What is the external iliac artery?
This nerve pierces the psoas major muscle.
What is the genitofemoral nerve?
This anatomical region is bounded by the rectus abdominis, inguinal ligament, and inferior epigastric vessels.
What is Hesselbach’s triangle?
The marginal artery forms an anastomosis between these two major vessels.
What are the SMA and IMA?
The correct order of layers in the lateral abdominal wall, superficial to deep.
What is: skin → superficial fascia → external oblique → internal oblique → transversus abdominis → transversalis fascia → peritoneum?
This vessel drains the sigmoid colon and flows into the portal system via the IMV.
What is the sigmoid vein?
These nerve roots form the thoracoabdominal nerves.
What are T7–T11?
A hernia protruding inferior to the inguinal ligament and medial to the femoral vein is this type.
What is a femoral hernia?
This retroperitoneal structure drains blood via the splenic vein to the portal vein.
What is the spleen?
The superficial fascia of the abdominal wall is divided into these two named layers.
What are Camper’s fascia and Scarpa’s fascia?
Lymph from the ileum drains primarily to these nodes.
What are the superior mesenteric nodes?
Parasympathetic innervation to the distal 1/3 of the transverse colon comes from these nerves
What are pelvic splanchnic nerves?
This structure forms the floor of the inguinal canal.
What is the inguinal ligament?
This ligament contains the portal triad.
What is the hepatoduodenal ligament?
This hernia type passes lateral to the inferior epigastric vessels and through the deep inguinal ring.
What is an indirect inguinal hernia?
These veins form a portosystemic anastomosis in rectal varices.
What are the superior rectal veins with middle/inferior rectal veins?
These nerves provide sympathetic innervation to the SMA and IMA plexuses.
What are the greater, lesser, and least thoracic splanchnic nerves?
This fascia contributes to forming the deep inguinal ring.
What is the transversalis fascia?
This condition results from compression of the left renal vein between the SMA and aorta.
What is Nutcracker syndrome?
