Answer to Question 1

A
Expressive aphasia, also known as motor, Broca, or nonfluent aphasia, is primarily a deficit in language output or speech production. Global aphasia results when a massive lesion affects the motor and sensory speech areas. The patient cannot transform sounds into words and cannot comprehend spoken words. Receptive aphasia, also referred to as sensory, Wernicke, or fluent aphasia, occurs when the connection between the primary auditory cortex in the temporal lobe and the angular gyrus in the parietal lobe is destroyed. Lesions in the parietal lobe and in other cortical structures can result in apraxia, an inability to perform a learned movement voluntarily.

Answer to Question 2

C
When the serum osmolality level increases, antidiuretic hormone is released from the posterior pituitary gland and stimulates increased water resorption in the kidney tubules. This expands the vascular space, returns the serum osmolality level back to normal, and results in more concentrated urine and an elevated urine osmolality level.
