EXAM ALREADY GRADED A+ PASS
When trying to identify the pancreas, what vascular landmark should
you look for directly posterior to the body and tail? Ans✓✓✓ Splenic
Vein
The portal vein is formed Ans✓✓✓ posterior to the neck of the
pancreas.
The tail of the pancreas Ans✓✓✓ lies between the stomach anteriorly
and left kidney posteriorly and extends to the splenic hilum.
The pancreas is descriptively divided into 5 parts. Name all five.
Ans✓✓✓ head, uncinate process, neck, body, tail
The acini cells produce the hormones insulin, glucagon, and somastatin.
Ans✓✓✓ False
Which statement best describes the anteroposterior dimensions of the
pancreas? Ans✓✓✓ The head is 2 to 3 cm; the neck is 1.5 to 2.5 cm;
the body is 2 to 3 cm; and the tail is 1 to 2 cm.
Sagittal scanning plane images of the pancreas show the gland in
transverse sections. Ans✓✓✓ True
,Pancreatic juice is comprised of nucleic acids and also enzymes that help
digest fats, proteins, and carbohydrates. Ans✓✓✓ True
The exocrine function of the pancreas is carried out by the beta cells.
Ans✓✓✓ False
The exocrine function of the pancreas is carried out by the acini cells.
Which statement best describes the locations of the neck, body, and tail
of the pancreas? Ans✓✓✓ The neck lies anterior to the porta-splenic
confluence; the body lies anterior to the SMA; and the tail lies just to the
left of the aorta.
The main pancreatic duct can be seen in the body of the pancreas.
Ans✓✓✓ True
The head of the pancreas lies Ans✓✓✓ to the right of the SMV, in the
C-loop of the duodenum, and anterior to the IVC.
The contour of the pancreas cannot be observed on ultrasound.
Ans✓✓✓ False
,Which statement describes the structures closely related to the head of
the pancreas? Ans✓✓✓ The common bile duct is posterolateral, and the
gastroduodenal artery is anterolateral.
Pancreatic juice reaches the duodenum via the common bile duct.
Ans✓✓✓ False
Pancreatic juice moves into the duodenum through the main pancreatic
duct (Wirsung's duct).
The CBD and GDA appear circular in the long axis (transverse view) of
the pancreas. Ans✓✓✓ True
On transverse views showing the longitudinal axis of the pancreas, two
small, circular, anechoic structures can be seen in the head of the
pancreas: the posterolateral CBD and the anterolateral GDA.
A water-filled stomach makes the pancreas more difficult to visualize.
Ans✓✓✓ False
Having the patient drink water can help the examiner identify parts of
the pancreas, especially the pancreatic head in the C-loop of the
duodenum.
In poorly prepped patients, shadows from the stomach and duodenum
obscure the pancreas and make it difficult to visualize. Ans✓✓✓ True
The pancreas is in close relationship to the portions of the small and
large intestine and their contents may affect sound beam transmission
, and obscure pancreatic structures. This is especially true for patients
who have been poorly prepped. Despite these obstacles, sonography has
become useful for the evaluation and early detection of diseases of the
pancreas.
Sonographically, the pancreas appears isoechoic to the liver. Ans✓✓✓
False
Echo texture of the normal pancreas varies and can appear homogeneous
to heterogeneous depending on the amount of interlobular fat that is
present. Generally the pancreas appears more echo-dense or hyperechoic
compared to the appearance of the normal liver.
Hormones that stimulate the formation of pancreatic juice are triggered
by chyme. Ans✓✓✓ True
Chyme in the duodenum stimulates the release of hormones, which in
turn act on pancreatic juice formation.
The pancreas is mostly an endocrine gland. Ans✓✓✓ False
The pancreas is mostly an exocrine (digestive) gland; only 2% of the
gland's weight is endocrine (hormonal) tissue.
The gastroduodenal artery divides into Ans✓✓✓ anterior and posterior
superior pancreaticoduodenal branches.
A small part of the ______ of the pancreas is enclosed in peritoneum.
Ans✓✓✓ head
