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.

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

Correct Answer - D
Ans. is 'd' i.e., Lesser omentum

Correct Answer -C
Ans. is 'c' i.e., Ventral rami of thoracic spinal nerves
Ventral rami of upper 11th thoracic spinal nerves are known as
intercostal nerves and ventral ramus of T12 is known as subcostal
nerve.
Upper six intercostal nerves supply thoracic wall whereas lower five
intercostal nerves and subcostal nerve supply thoracic and anterior
abdominal walls and hence known as thoracoabdominal nerves.
Upper two intercostal nerves also supply the upper limb.
Thus only 3rd to 6th are called typical intercostal nerves.

In posterior dislocation of shoulder there is
internal rotation of humeral head.
◦ Hence, in the AP film, the shape of humeral
head appears like that of Electric bulb called
as 'light bulb sign.'

Correct Answer - B
Ans. is 'b'i.e., Anterior wall
• The middle ear is shaped like a cube
• When seen in the coronal section, the cavity of the middle ear is
biconcave.
• The boundaries of the middle ear are as follows :
1. Roof or tegmental wall
• Separates the middle ear from the middle cranial cavity.
• It is formed by a thin plate of bone called tegmen tympani.
2. Floor or jugular wall
• Formed by a thin plate of bone which separates the middle ear from
the superior bulb of the internal jugular vein
• The floor also presents the tympanic canaliculus which transmits the
tympanic branch of the glossopharyngeal nerve
3. Anterior or carotid wall
• The uppermost part bears the opening of the canal of the tensor
tympani.
• The middle part has the opening of the auditory tube.
• The inferior part of the wall is formed by a thin plate of bone which
forms the posterior wall of the carotid canal. This plate separates the
middle ear from the internal carotid artery.
4. Posterior or mastoid wall
