objects held in your hand.

What will be an ideal response?

Answer 1

Being able to say words is the main responsibility of Broca's area, located in the left frontal lobe. Understanding spoken words is the responsibility of Wernicke's area, located in the left cortex at the juncture of the parietal, temporal, and occipital lobes. Being able to voluntarily raise your arm is the responsibility of the primary motor cortex, located in the region of the frontal lobe just anterior to the central sulcus. The ability to distinguish shapes of objects, also known as spatial discrimination, is the responsibility of the somatosensory cortex, located immediately anterior to the central sulcus.
