When blood glucose levels are too high the beta cells of the pancreas release blank to decrease levels?
The most important hormone that the pancreas produces is insulin. Insulin is released by the ‘beta cells’ in the islets of Langerhans in response to food. Its role is to lower glucose levels in the bloodstream and promote the storage of glucose in fat, muscle, liver and other body tissues.
Which of the following adrenal hormones affect glucose homeostasis?
The adrenal medulla contains two types of secretory cells: one that produces epinephrine (adrenaline) and another that produces norepinephrine (noradrenaline)….Endocrine Glands.
| Endocrine Gland | Associated Hormones | Effect |
|---|---|---|
| Pancreas | insulin | reduces blood-glucose levels |
| glucagon | increases blood-glucose levels |
What is the production of glucose by liver cells in response to cortisol called?
Glucose and Protein Homeostasis In the liver, high cortisol levels increase gluconeogenesis and decrease glycogen synthesis. [7] Gluconeogenesis is a metabolic pathway that results in the production of glucose from glucogenic amino acids, lactate, or glycerol 3- phosphate found in triglycerides.
Which of the following homeostatic imbalances usually results from deficits in both glucocorticoids?
19 Which of the following homeostatic imbalances usually results from deficits in both glucocorticoids and mineralocorticoids? Addison’s disease, the major hyposecretory disorder of the adrenal cortex, usually involves deficits in both glucocorticoids and mineralocorticoids.
How does glucagon increase blood glucose levels?
When blood glucose falls, cells in the pancreas secrete glucagon. Glucagon instructs the liver to convert glycogen to glucose, making glucose more available in the bloodstream. From there, insulin attaches to its receptors on the body’s cells and ensures that they can absorb glucose.
What are the factors causing increased blood glucose by glucagon check all that apply?
Factors that cause increased blood glucose by glucagon are increased glycogenolysis in the liver, increased gluconeogenesis in the liver, decreased glycogenesis in the liver, decreased lipogenesis in fat cells, and increased lipolysis in fat cells.
What is the receptor in blood glucose homeostasis?
Blood glucose control depends heavily on proteins called G-protein-coupled receptors (GPCRs). GPCRs span cell membranes to relay signals from the outside in. Once activated by the binding of a substance, GPCRs trigger a cascade of responses inside the cell.
When blood glucose levels are high a liver cell responds to insulin by?
A spike in insulin signals to the liver that blood glucose is also high. The liver absorbs glucose then changes it into a storage molecule called glycogen. When blood sugar levels drop, glucagon instructs the liver to convert the glycogen back to glucose, causing blood sugar levels to return to normal.
Which of the following stimulates most body cells to increase and divide?
CH16 – Endocrine Sys
| Question | Answer |
|---|---|
| The anterior pituitary is known as the “master endocrine gland” because it controls the hypothalamus. | False |
| Which of the following stimulates most body cells to increase in size and divide? | Growth hormone |
Which of the following hormones stimulate gamete sperm or egg production?
endocrine/hormones
| Question | Answer |
|---|---|
| Which of the following stimulate(s) most body cells to increase in size and divide? | GH |
| Which of the following hormones stimulates gamete (sperm or egg) production? | FSH |
| As blood levels of __________ rise, the expulsive contractions of labor gain momentum and finally end in birth. | OXYTOCIN |
What causes an imbalance in the homeostatic system?
It can be caused by a number of factors which include the aging of the person’s organs and the organ’s control systems or feedback mechanisms, external disruption, such as hot weather, or an internal disruption, such as a fall in blood glucose levels.
Which is the best description of impaired homeostasis?
Impaired homeostasis (or homeostatic imbalances) can be described as a condition in which the human body’s internal environmental variables become disturbed.
Can a person with dementia have a homeostatic imbalance?
The permanent disruptions, or homeostatic imbalance, can be caused by diseases of the mind. A person with dementia, for example, may experience confusion, forgetfulness, or profound and rapid changes in their personality.
Which is an example of a homeostatic control mechanism?
All homeostatic control mechanisms have at least three interdependent components for the variable being regulated: A sensor or receptor that detects changes in the internal or external environment. An example is peripheral chemoreceptors, which detect changes in blood pH.
