Q

Liver Blood Supply & Innervation

A

Blood: Celiac trunk via proper hepatic artery
Innervation: vagus nerve (parasympathetic); thoracic sympathetic trunk T5-T9 (sympathetic), sensation pathways: unconscious/reflex (vagus) pain (sympathetic)

Foregut

Q

Suprarenal gland Function

A

Produce hormones to regulate stress and other metabolic functions

15
Q

Renal pelvis Function

A

Collect urine from major calyces to drain into ureter

Junction between calyces and ureter-common location for kidney stones to be trapped

Blood supply/ innervation same as kidney

16
Q

Suprarenal gland Blood Supply & Innervation

A

Blood: Suprarenal arteries

Innervation: vagus nerve (parasympathetic); thoracic sympathetic trunk T10-T12 (sympathetic), sensation pathways: unconscious/reflex (vagus) pain (sympathetic)

Located superior to each kidney

17
Q

Common Hepatic Duct Arises From/Drains

A

Hepatic ducts of liver

18
Q

Common Hepatic Duct Enters/Drains Into

A

Common bile duct

19
Q

Cystic duct Enters/Drains Into

A

Common bile duct

Notes: Relationship with the cystic artery is variable and important for surgery

20
Q

Cystic duct Arises From/Drains

A

Gallbladder

21
Q

Common bile duct Arises From/Drains

A

Common hepatic duct, cystic duct

22
Q

Common bile duct Enters/Drains Into

A

Major duodenal papilla

23
Q

Ureter Arises From/Drains

A

Renal pelvis

24
Q

Ureter Enters/Drains Into

A

Bladder

Notes: Passes inferiorly over external iliac artery/pelvic inlet-common location for kidney stone lodging, another location is the junction between renal pelvis and ureter, and between the ureter and bladder
