Ventral pancreatic duct give rise to ?
#NEET PG #INICET #PYQ #FMGE
rrect Answer-D
Ans. is 'd' i.e., Uncinate process
Development of pancreas
• Pancreas is developed from the two pancreatic buds.
.. Dorsal pancreatic bud :- It is larger and most of the pancreas is
derived from it i.e. most of the head, and whole neck, body & tail.
2. Ventral pancreatic bud :- It is smaller and forms lower part of the
head of pancreas including uncinate process
• uring 7th week of development, the ventral and dorsal pancreatic
buds fuse to form a single pancreatic mass
• After the fusion of ventral and dorsal pancreatic buds, their ducts
develop cross communications. Final duct system is formed as
below ?
.. Main pancreatic duct (Duct of wirsung) is formed by the duct of
ventral bud, distal part of duct of dorsal bud and an oblique
communication between the two. The main pancreatic duct join the
bile duct to form hepatopancreatic ampulla that enters th 2nd part of
duodenum at major duodenal papilla.
‣. Accessory pancreatic duct is formed by the proximal part of the duct
of dorsal bud. It opens into 2nd part of duodenum at minor duodenal
papilla, 2 cm proximal (cranial) to major duodenal papilla.
Anomalies of pancreatic development may be:
.. Annular pancreas :- Two components of the ventral bud fail to fuse


and grow in oppsite direction arround the duodenum and meet the
dorsal pancreatic duct.
?. Pancreatic divisum (divided pancreas) :- Ventral and dorsal buds fail
to fuse with each other. It is the most common congenital anomaly of
pancreas.
3. Inversion of pancreatic duct :- The main pancreatic duct is formed
the duct of dorsal bud, i.e. accessory duct is larger than the main
duct and the main drainage of pancreas is through the minor
duodenal papilla.
I.Accessory pancreatic tissue :- May be found in ?
• Wall of stomach, duodenum, jejunum or ileum

* Sensory neurons of 5th, 7th, 8th, 9th, 10th cranial nerve ganglia
(trigeminal, geniculate, sphenopalatine, submandibular, cochlear,

. The MOST common type of dislocation of elbow joint is:
#NEET PG #FMGE #INICET #PYQ
Correct Answer- A
In adults, the elbow is the second most frequently dislocated major joint, after the shoulder.
It is the most commonly dislocated joint in children. More than 90% of all elbow dislocations
are posterior dislocations.


This injury entails disengagement of the coronoid process of the ulna from the trochlea of
the humerus with movement posteriorly.
The mechanism of injury is typically a fall onto an outstretched hand with the elbow in
extension upon impact.

65-year-old lady presents with a
vascular injury to the inferior frontal
gyrus. Which functional area would mostly be affected? #NEET PG #INICET #PYQ #FMGE
Ans: D. Motor speech
Motor speech defect is also called apraxia of speech.
Injury to the Broca's area/left inferior frontal gyrus causes motor
speech defect.

"Typical intercostal nerves are the ones that are confined to their
own intercostal spaces in the thoracic wall. The third, fourth, fifth and
sixth intercostal nerves are the typical nerves"

EXCEPT: #NEET PG #INICET #PYQ #NEET
Correct Answer-B
The pterygopalatine fossa is the region between the
pterygomaxillary fissure and the nasal cavity
* The fossa accommodates branches of the maxillary nerve [cranial
nerve (CN) V-2], the pterygopalatine ganglion, the terminal
branches of the maxillary artery, and greater superficial petrosal
nerve.

31. Pulled Elbow is:
#NEET PG #INICET #FMGE #PYQ
Correct Answer -C
C i.e. subluxation of proximal radio ulnar joint
. If a young child is lifted by the wrist, the head of the radius may be
pulled partly out of the annular ligament, i.e., subluxation of the head
of the radius.
It occurs when forearm is pronated, elbow is extended and
longitudinal traction is applied to the hand or wrist, e.g., lifting,
spinning or swinging a child with wrist or hand. Pulled elbow most
commonly occurs between the age of 2-5 years
