What is the difference between cystic duct and bile duct?
The cystic duct connects the gallbladder (a small organ that stores bile) to the common bile duct
The common bile duct: passes through the pancreas before it empties into the first part of the small intestine (duodenum).

What is a TIPS? [1]: transjugular intrahepatic portosystemic shunt
Why would this process be used? [1]: keep flow back to the heart whilst bypassing the liver
Label A & B [2]

Describe the arterial supply to the thyroid [2]
And their sources [2]
- The superior thyroid artery (STA) arising from the external carotid artery (ECA)
- The inferior thyroid artery (ITA) branching from the thyrocervical trunk
Describe venous drainage & route of the thyroid [5]
The thyroid gland is drained via the superior, middle, and inferior thyroid veins: form a venous plexus around the thyroid gland. [3]
Superior and middle veins drain into the internal jugular vein [1]
Inferior vein: empties into the brachiocephalic vein [1]
The superior, middle and inferior thyroid veins are responsible for the venous drainage of the thyroid gland. Where does the inferior thyroid vein empty into?
External jugular vein
Internal jugular vein
Brachiocephalic vein
Facial vein
The superior, middle and inferior thyroid veins are responsible for the venous drainage of the thyroid gland. Where does the inferior thyroid vein empty into?
External jugular vein
Internal jugular vein
Brachiocephalic vein
Facial vein
Which embryological remnant might explain a central neck lump which ascends on tongue protrusion?
Branchial cyst
Thyroid nodule
Cystic hygroma
Thyroglossal cyst
Which embryological remnant might explain a central neck lump which ascends on tongue protrusion?
Branchial cyst
Thyroid nodule
Cystic hygroma
Thyroglossal cyst
A thyroglossal cyst arises from a failure of the thyroglossal duct to regress during development. It typically presents as a midline lump in the anterior neck which rises on tongue protrusion

Describe the blood supply to the adrenal glands? [3] & sources? [3]
The adrenal glands have a rich blood supply via three main arteries:
Superior adrenal artery – arises from the inferior phrenic artery
Middle adrenal artery – arises from the abdominal aorta.
Inferior adrenal artery – arises from the renal arteries.
