1) Internal spermatic fascia is derived from

a. Transversalis facia

b. Internal abdominis muscle

c. External Oblique Abdominis Muscle

d. Internal Oblique Abdominis Muscle

Answer a. Transversalis Fascia

Reference: Grays’ Anatomy 38^th Edition Page 829

The spermatic cord in the male, or the round ligament of the uterus in the female, pass through the transversalis fascia at the deep inguinal ring (see below). This opening is not visible externally since the transversalis fascia is prolonged on these structures as the internal spermatic fascia

2) Length of Ureter is

a. 25 cms

b. 18 cms

c. 10 cms.

d. 5 cm

Answer 25 cm

Reference : Grays 38^th Edition Page 1828

Ureter measures 25 to 30 cm

3) External laryngeal nerve supplies

a. Superior Constrictor.

b. Middle Constrictor.

c. Inferior constrictor.

d. None of the above

Answer : Inferior Constrictor

Reference: Gray 38^th Edition Page 1253

The external laryngeal nerve, smaller than the internal, descends posterior to the sternothyroid with the superior thyroid artery but on a deeper plane; it lies at first on the inferior pharyngeal constrictor and then, piercing it, curves round the inferior thyroid tubercle to reach and supply the cricothyroid. It also supplies the pharyngeal plexus and inferior constrictor; behind the common carotid artery it connects with the superior cardiac nerve and superior cervical sympathetic ganglion.

4) Vidian Nerve is formed by

a. Deep Petrosal & Greater Superficial Petrosal nerve

b. Greater Superficial Petrosal Nerve and Lesser Superficial Petrosal Nerve.

c. Deep Petrosal Nerve and Lesser Superficial Petrosal Nerve

d. None of the above

Answer Deep Petrosal & Greater Superficial Petrosal nerve

Reference: Gray 38^th Edition Page 1245

Greater Petrosal Nerve is joined by the deep petrosal nerve from the internal carotid sympathetic plexus to become the Vidian nerve or nerve of the pterygoid canal which traverses the pterygoid canal to end in the pterygopalatine ganglion.

5) Superficial Surface of Parotid is related to

a. Great auricular nerve

b. Mastoid Process

c. Posterior Belly of Digastri

d. External Carotid Artery

Answer a. Greater Auricular Nerve

Reference Gray 38^th Edition Page 1691

6) The communicating vein responsible for spread of infection from the Dangerous area of the face.

a. Superior ophthalmic Vein

b. Inferior Ophthalmic Vein

c. Maxillary Vein

d. Lingual Vein

Answer : Superior Ophthalmic Vein

Reference: Gray 38^th Edition Page 1577

Near its beginning the facial vein connects with the superior ophthalmic directly and via the supraorbital; it is thus connected to the cavernous sinus.

7) Para thyroid Develops from

a. 1^st and 2^nd Arch

b. 2^nd and 3^rd Arch

c. 3^rd and 4^th Arch

d. 4^th and 5^th Arch

Answer : 3^rd and 4^th Arch

8) Preganglionic fibres of of Otic Ganglion travels in

a. Lesser Petrosal nerve

b. Auriculotemporal nerve

c. Greater Superficial Petrosal Nerve

d. None of the above

Answer : Lesser Petrosal Nerve

Reference: Gray 38^th Edition Page 1377

9) Left common Cardinal Vein forms

a. Oblique Vein of Left Atrium

b. SVC

c. Coronary Sinus

d. None of the above
