A polymodal brain region is an association are whose neurons
have
receptive fields defined by MORE THAN ONE sensory modality (e.g.,
vision,
somatosensations or vision/hearing, etc.) Discuss the adaptive
significance of the
expansion of the polymodal regions PG and STS in humans compared to
other
primates.

Which statement is true about the role of the pancreas?
a. The exocrine cells of the pancreas secrete insulin and glucagon into the duodenum.
b. The endocrine cells of the pancreas secrete zymogens into the duodenum.
c. The exocrine cells of the pancreas secrete zymogens into the blood.
d. The endocrine cells of the pancreas secrete insulin and glucagon into the blood.
Which statement is true about the role of the autonomic nervous system in controlling the digestive process?
a. Parasympathetic neurons or the smell of food can activate the cephalic phase of digestion, leading to increased gastric secretions.
b. Sympathetic neurons or the smell of food can activate the cephalic phase of digestion, leading to decreased gastric secretions.
c. Parasympathetic neurons or the smell of food can activate the cephalic phase of digestion, leading to decreased gastric secretions.
d. Sympathetic neurons or the smell of food can activate the cephalic phase of digestion, leading to increased gastric secretions.
Which statement about regulation of the digestive process is correct?
a. Beta cells of the pancreas have receptors for GIP which produce insulin when stimulated, causing an increase in levels of blood glucose.
b. Beta cells of the pancreas have receptors for CCK which produce insulin when stimulated, causing an increase in levels of blood glucose.
c. Beta cells of the pancreas have receptors for CCK which produce insulin when stimulated, causing a decrease in levels of blood glucose.
d. Beta cells of the pancreas have receptors for GIP which produce insulin when stimulated, causing a decrease in levels of blood glucose.
