4 - Anatomy Mcqs - 11 to 22

11. 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 38th 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

12) Length of Ureter is
a. 25 cms
b. 18 cms
c. 10 cms.
d. 5 cm
Answer 25 cm
Reference : Grays 38th Edition Page 1828
Ureter measures 25 to 30 cm

13) External laryngeal nerve supplies
a. Superior Constrictor.
b. Middle Constrictor.
c. Inferior constrictor.
d. None of the above
      Answer : Inferior Constrictor
Reference: Gray 38th 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.

14) 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 38th 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.

15) 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 38th Edition Page 1691

16) 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 38th 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.

17) Para thyroid Develops from
a. 1st and 2nd Arch
b. 2nd and 3rd Arch
c. 3rd and 4th Arch
d. 4th and 5th Arch
Answer : 3rd and 4th Arch
Reference: Gray 38th Edition Page 1897

18) 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 38th Edition Page 1377

19) Left common Cardinal Vein forms
a. Oblique Vein of Left Atrium
b. SVC
c. Coronary Sinus
d. None of the above
Answer : (A) Oblique Vein of the Left Atrium

20) Auditory cortex area is Area
a. Area 14
b. Area 24
c. Area 34
d. Area 44
Answer : D) Area 44

b. Starling’s law.
c. Both of the above
d. None of the above
Answer A)Bell magendie law
Reference: Ganong 22nd Edition Page 129

22) Superior oblique muscle is supplied by
a. Trochlear nerve.
b. Abducens Nerve
c. Oculomotor Nerve
d. None of the above
