What else can I help you with?
In response to low blood sugar the alpha cells of the pancreatic islets secrete?
glucagon
True or false- The beta cells of the pancreatic islets secrete glucagon in response to low blood sugar levels?
False. Beta cells of the pancreatic islets secrete insulin in response to high blood sugar levels, not glucagon. Glucagon is secreted by alpha cells in the pancreatic islets in response to low blood sugar levels to raise blood sugar levels.
What gland controls blood sugar levels?
pancreatic islets
What are the four types of endocrine cell in pancreatic islets?
The four types of endocrine cells in the pancreatic islets, also known as the islets of Langerhans, are alpha cells, beta cells, delta cells, and pancreatic polypeptide cells. Alpha cells produce glucagon, which raises blood glucose levels; beta cells secrete insulin, lowering blood glucose levels; delta cells release somatostatin, which regulates the endocrine system and inhibits insulin and glucagon secretion; and pancreatic polypeptide cells produce pancreatic polypeptide, which is involved in regulating both endocrine and exocrine pancreatic function.
Where are the islets located in the body?
The islets of Langerhans are located in the pancreas and they secrete insulin, which stimulate the cells to absorb glucose in the bloodstream (lowering blood sugar).
What Types of cells are in the pancreas?
The pancreas has several cell types. The pancreas forms these small pouches that are formed by acinar cells, which make the proteins and enzymes in pancreatic fluid. These pouches then lead into intercalated ducts. The first cells here are centroacinar cells, which secrete bicarbonate. The rest of the ducts are lined by duct cells that change the electrolytic composition of pancreatic fluid. The pancreas also contains Islets of Langerhan. Within these islets you can find beta cells(produce insulin), alpha cells(produce glucagon), delta cells(produce somatostatin), epsilon cells(produce ghrelin), and PP cells(produce pancreatic polypeptide). Hope that helps.
Which pancreatic cells secrete insulin?
A group called beta pancreatic cells produce insulin. Insulin is a molecule which carries glucose across the cell membrane. Alpha pancreatic cells produce glucagon which is involved in reducing glycogen stored in the liver into glucose.
What are the key features of pancreatic islets histology?
The key features of pancreatic islets histology include clusters of cells called islets of Langerhans, which contain different types of hormone-producing cells such as alpha, beta, and delta cells. These cells are arranged in a specific pattern within the islets and play a crucial role in regulating blood sugar levels and metabolism.
Which part of the endocrine system is responsible for controlling blood sugar levels and glucose metabolism throughout the body?
pancreatic islets
What type of organelle would be in the greatest abundance if it were located in a very active area of an organism?
Islets of Langerhans organelles are abundant in the pancreas. They are endocrine cells that produce and secrete hormones into the bloodstream. Pancreatic hormones (insulin & glucagon) work together to maintain the proper level of sugar in the blood.
Which population serves the digestive process- islets or acinar cells?
Acinar cells secrete digestive enzymes that break down food in the digestive process. Islets of Langerhans, on the other hand, secrete hormones like insulin and glucagon that regulate blood sugar levels in the body.
Hormones produced by the pancreatic islets affect the body's use of?
Hormones produced by the pancreatic islets affect the body's use of glucose and regulate blood sugar levels. Specifically, insulin is responsible for lowering blood sugar levels by promoting the uptake of glucose into cells for energy or storage, while glucagon raises blood sugar levels by stimulating the release of glucose from stores such as the liver.
