Release of ACTH is stimulated by corticotropin releasing hormone (CRH) from the hypothalamus in response to stress or low levels of cortisol in the body.
Yes, insulin secretion is stimulated by elevated blood glucose concentrations. Elevated blood glucose levels trigger the release of insulin from the beta cells in the pancreas, which helps to facilitate the uptake and storage of glucose by cells in the body.
ACTH (adrenocorticotropic hormone) is stimulated by corticotropin-releasing hormone (CRH) that is released from the hypothalamus in response to stress or low levels of cortisol in the blood. This results in the release of ACTH from the pituitary gland, which then stimulates the adrenal glands to produce cortisol.
In patients with severe chronic respiratory conditions, respiration is primarily stimulated by high levels of carbon dioxide (hypercapnia) in the blood rather than low levels of oxygen. This is due to changes in the body's sensitivity to carbon dioxide over time, leading to an altered respiratory drive. Additionally, other factors such as acid-base balance and oxygen saturation also play a role in regulating respiration in these patients.
Chemoreceptors are stimulated by changes in the chemical composition of the external environment, such as the presence of specific molecules or ions in the surroundings. In the human body, chemoreceptors play a crucial role in detecting changes in oxygen and carbon dioxide levels in the blood, as well as in responding to odors and tastes in the environment.
Ghrelin is known as the "hunger hormone" because it stimulates appetite and food intake. It is produced mainly by the stomach and plays a role in regulating energy balance and body weight. Ghrelin levels increase before meals and decrease after eating.
The stomach
Release of ACTH is stimulated by corticotropin releasing hormone (CRH) from the hypothalamus in response to stress or low levels of cortisol in the body.
When sodium levels increase, an animal is stimulated to drink more water in order to help restore electrolyte balance within the body. This helps to dilute the excess sodium in the bloodstream and maintain proper hydration levels.

Ghrelin and Bulimia Nervosa (BN) Kalat (2007) discusses the phenomenon of increased release of the hormone ghrelin in those with BN. When compared with controls, those with BN had increased levels of ghrelin both pre- and postprandial (before and after meals)due to reduced ghrelin suppression (Jerlhag et al., 2006). According to the Journal of Clinical Investigation (2006) ghrelin assists in the balance of food intake, and energy output. Raised ghrelin increases food intake and weight gain (Kojima et al., 2005). Kalat (2007) reports that ghrelin has a role in stimulating stomach contractions upon food deprivation. Increased ghrelin is found in obese individuals with Prader Willi Syndrome, those with BN, and those with anorexia nervosa. Elevated levels of ghrelin may be associated with the oft reported feeling of loss of control during binge eating episodes (Kojima et al., 2005). It is postulated that increased levels of ghrelin boost production of dopamine, a neurotransmitter implicated in the reward system associated with addictive behavior (Jerlhag et al., 2006). Furthermore, Jerlhag et al. (2006) posited that the inhibition of nicotinic receptors by injecting nicotinic acetylcholine antagonists would decrease the effects of ghrelin. Similar to its involvement in other addictive behaviors, ghrelin may be involved in compulsive eating via neurotransmitter and hormonal pathways of the reward system (Jerlhag et al., 2006). Thus, it is proposed that psychopharmaceutical and clinical treatments might be developed to treat BN as an addiction and target symptoms when ghrelin is more clearly understood.
Ghrelin and Leptin

Hunger signals like stomach growling and low energy levels tell us when to eat, while feeling full and satisfied tells us when to stop eating. Hormones like ghrelin and leptin also play a role in regulating appetite and signaling hunger and satiety. Eating mindfully and paying attention to these signals can help us maintain a healthy relationship with food.
When we're tired, our body releases higher levels of the hormone ghrelin, which can leave us feeling hungry even when we don't need food. It can also be as a result of stress
The Ghrelin hormone is an appetite regulating hormone. It is produced in the pancreas and also functions in helping growth. It also plays a role in adapting to environment change and the learning processes.
When the stomach is empty, it secretes the hormone ghrelin. Ghrelin is often referred to as the "hunger hormone" because it stimulates appetite and promotes food intake. It signals the brain to increase the sensation of hunger, prompting the individual to seek food. Additionally, ghrelin may play a role in energy balance and metabolism.
