Anterior to the spine

Right of the aorta

Courses anteriorly to enter right atrium

Anterior to the portal vein

Left of the common bile duct

Superior to the head of the pancreas

Posterior to the body of the pancreas and the splenic vein

Anterior to the aorta

Posterior to the body and tail of the pancreas

Inferior to the splenic artery

Anterior to the aorta

Posterior to the superior mesenteric artery

Anterior to the right renal artery

Anterior to the portal vein

Right of the hepatic artery

Toward the head, closer to the head, the upper portion of the body, the upper part of a structure, or a structure higher than another structure

For example the left lung lobe is superior to the left liver lobe

Toward the feet, away from the head, the lower portion of the body, toward the lower part of a structure, or a structure lower than another structure

for example: the lower pole of each kidney is inferior to the upper pole

Toward the front or at the front of the body or a structure in front of another structure

For eg. The main ortal vein is anerior to the inferior vena cava

Toward the back or the back of he body or a structure behind another structure

for eg. the main portal vein is posterior to the common hepatic artery

Toward the middle or midline of the body or the middle of a structure

for eg. the middle vein is medial to the right hepatic vein

Away from the middle or the midline of the body or pertaining to the side

for eg. the right kidney is lateral to the inferior vena cava

located on the same side of the body or affecting the same side of the body

for eg. the gallbladder and right kidney are ipsilateral

located on the opposite side of the body or affecting the opposite side of the body

for eg. the pancreatic tail and pancreatic head are contralateral

closer to the attachment of an extremity to the trunk or the origin of a body part

for eg. the thoracic aorta is proximal to the abdominal aorta

farther from the attachment of an extremity to the trunk or the origin of a body part

for eg. the iliac arteries are distal to the abdominal aorta

toward or on the body surface or external

for eg. the testicles are considered superficial structures

away from the body surface or internal

for eg. the prostate is a deep structure
