Taste sensation from the anterior two-thirds of the tongue is carried by the:
सही उत्तर: ख) Chorda tympani branch of the facial nerve

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
