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

Correct Answer- A Uvula vesicae is a small elevation situated immediately behind the urethral orifice, which is produced by the underlying median lobe of the prostate. It enlarges with age due to enlargement of the underlying median lobe of the prostate and may inhibit complete bladder emptying.

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.

Correct Answer-C Ans. is 'c' i.e., Anterior mediastinum • Esophagus mainly descends in superior and posterior mediastinum • Esophagus is usually not a content of middle mediastinum, but it forms posterior boundry of middle mediastinum (BDC Vol.-1, 6`"/e p. 246). • Esophagus has no relation to anterior mediastinum. Thus, among the given options, best answer is anterior mediastinum
