| Re: All India PG Medical Entrance Exam Previous Question Papers
Well below I have given you the previous paper for the All India PG Medical Entrance Exam so you can have a look ANATOMY 1. In the advancement of surgery of shoulder joint, one muscle was not given much importance earlier but now came in picture, this forgotten muscle of rotator cuff is a. Subscapularis b. Supraspinatus c. Infraspinatus d. Teres minor Answer: (a) Subscapularis Reference: Explanation:Musculotendinous cuf f of shoulder is a fibrous sheath formed by the four flattened tendons which blend with the capsule of shoulder joint and strengthen it. Muscles which form the cuff arise from scapula and are inserted into the lesser and greater tubercles of humerus. They are subscapularis, supaspin- taous, infraspinatus and teres minor. There tendons while crossing the shoulder joint become flattened and blend with each other on one end and with capsule of the joint on the other end, before reaching their points of insertion.Cuff gives strength to the capsule of shoulder joint all around except inferiorly. That is why dis- location of humerusoccur most commonly in a down ward insertion. 2. Stuctures at anorectal junction all except a. External sphincter b. Internal sphincter c. Anococcygeal raphe d. Puborectalis Answer (c)Anococcygealraphae Reference: BDC 2nd vol,5/e, pg.414 Explanation: Anorectal ring is a muscular ring present at the anorectal junction. It is formed by the fusion of the puborectalis, uppermost fibers of external sphincter and internal sphincter. Sur gical division of anorectal ring results in rectal incontinence. Anococcygeal ligament or anococcygeal raphe is a multilayer musculotendinous structure between anal ca- nal & hip of coccyx. It is attached anteriorly to the superficial part of external anal sphincter i.e. middle part of external anal sphincter which lies below to deep part of external anal sphincter at the anorectal junction present deep part of external anal sphincter. 3. Structure not present at floor of third ventricle- a. Optic stalk b. Third nerve c. Infundibulum d. Mamillary body Answer: (b) Third nerve (Occulo motor N.) Reference: BDC 3rdvol, 5/e, pg. 428 Explanation: Third ventricle is a median cleft b/w two thalami. Embryologically it represents the cavity of diencephalon. Communication :Antero superiorly, on each side it communicates with the lateral ventricle through the interventriclar foramen (or Foramen of Monro). Postero inferiorly it communicates with the fourth ventricle through the Cerebral Aqueduct. Boundaries: Anterior wall – i. Lamina terminalis ii. Anterior commissure iii. Anterior columns of fornix Posterior wall – i. Pineal body ii. Post commissure iii. Cerebral aqueduct Roof - i. Ependymal liningof the under surface of telachoroidea of third ventricle.
