True about circumcaval ureter ?
Correct Answer - C
• Circumcaval (retrocaval) ureter results from altered vasculature
rather than ureteral development. Thus, preureteral vena-cava is
more appropriate term.
• This disorder involves right ureter which passes behind IVC winding
about and crosses in front of it from medial to lateral direction.
The anomaly is divided into two types :?
1) Type 1 : It is more common and has hydronephrosis with a
typically obstructing pattern demonstrating some degree of fish-hook
shaped deformity of ureter.
2) Type 2 : It has lesser degree of hydronephrosis or not at all.

Cranial part of accessory nerve supplies all palatal muscles, EXCEPT?

a)
Correct Answer-C
The cranial root of the accessory nerve is smaller than the spinal
root. It exits the skull through the jugular foramen and unites for a
short distance with the spinal root. Its fibers innervate the
pharyngeal and palatal muscles, except tensor veli palatini.
Because the cranial part of accessory nerve (CN XI) leaves the
jugular foramen as joining the CN X, it is sometimes considered part
of the plexus as well
The tensor veli palatini is supplied by the medial pterygoid nerve, a
branch of mandibular nerve, the third branch of the trigeminal nerve
- the only muscle of the palate not innervated by the pharyngeal
plexus
