Broca's motor speech area is located in the:
सही उत्तर: ग) Inferior frontal gyrus of the dominant hemisphere
Broca's area (Brodmann 44, 45) lies in the inferior frontal gyrus; lesions give non-fluent (expressive) aphasia with preserved comprehension. Wernicke's area in the superior temporal gyrus gives fluent aphasia with poor comprehension.

Meckel's diverticulum is a remnant of the:
सही उत्तर: घ) Vitello-intestinal duct

The superior oblique muscle of the eye is supplied by the:

-
Which cranial nerve passes through the cavernous sinus itself, close to the internal carotid artery, rather than in its lateral wall?
सही उत्तर: ग) Abducent nerve (VI)
The abducent nerve runs within the sinus lateral to the internal carotid artery, so it is often the first nerve affected in cavernous sinus lesions. CN III, IV, V1 and V2 lie in the lateral wall.

The 'dangerous layer' of the scalp is the:
सही उत्तर: ख) Loose areolar tissue
The loose areolar tissue (fourth layer) contains emissary veins that connect scalp veins to the intracranial venous sinuses, so infection here can spread inside the skull. The dense connective tissue layer holds the blood vessels that bleed profusely when cut.

Which of the following structures does NOT pass through the carpal tunnel?
सही उत्तर: ग) Ulnar nerve
