Answer:
Pancreas; islet of langerhans
Explanation:
Insulin and Glucagon are both hormones released into the bloodstream with the function of regulating blood sugar level. Insulin is released when the blood sugar level (glucose) is high, hence, it converts excess glucose to glycogen, which is stored in muscles. Insulin also helps the cell to utilize glucose as an energy source. Glucagon, on the other hand, functions to convert stored glycogen to glucose (glycogenolysis) when the glucose levels in the blood is low.
Both hormones i.e. Insulin and Glucagon are secreted into the bloodstream by an endocrine gland called PANCREAS, which is a digestive organ found near the stomach. Specifically, the pancreas contains regions that contain endocrine cells called ISLET CELLS. This region, called Islet of Langerhans, is where the hormones are produced in the PANCREAS.
All the things that we can sense have their origins in the PERIPHERAL NERVOUS SYSTEM.
The peripheral nervous system is made up of all the nerves that are located outside the spinal cord. These nerves transport information to and from the central nervous system. The sensory cells are involved in carrying information from the peripheral nervous system to the central nervous system. The sensory cells include the cells that are responsible for sight, sound, smell, taste and pressure.<span />
