Signals from higher brain centers:Nerve cells in the hypothalamus and cortex also influence the activity of the respiratory centers. During pain or strong emotions, the hypothalamus will tell the respiratory centers to speed up. Nerve centers in the cortex can voluntarily tell the respiratory center...
The hypothalamus watches over the state of the body, looking for just the right system-wide conditions to support puberty. One of the main ones is the level of a hormone called leptin, which is produced in fat cells. When body fat reaches a certain level and there's enough leptin, the ...
Noradrenaline.Also called norepinephrine, noradrenaline works alongside adrenaline to activate the fight or flight response. Its primary job is to increase and manage blood pressure. Noradrenaline also has several uses as a medication. It’s used to elevate blood pressure in the short term or in em...
The release of GnRH is controlled by the hypothalamus, the same part of the brain that regulates your temperature and your sleep cycle, as well as your senses of hunger and thirst. With that in mind, let's take a look at the different stages of puberty. While not strict guidelines, ...

Detecting pyrogens, the hypothalamus dials up the heat and tells the body not to let it out. Luckily the viruses and bacteria that make us sick are heat-sensitive. The idea is to make things hot enough to cook the bacteria or viruses until they're dead. Seems like a good idea as long...
Explain how the nervous system works with each of the other human body systems. Nervous System: The nervous system of the body helps in the control and coordination of the body with some different parts. It regulates the adjustments with the different physiological functions of ...
suppression and weight-lowering, whereas targeted knockdown in the hypothalamic regions, such as the paraventricular nucleus of the hypothalamus (PVN) and arcuate nucleus of the hypothalamus (Arc), fails to replicate the effect. This suggests that GLP-1Rs in LS mediated the anorectic effect of ...
During menopause, declining estrogen levels cause the body to become more sensitive to a chemical called neurokinin B (NKB). NKB is in thehypothalamus, or the temperature regulation center. This chemical causes vasomotor symptoms, or hot flashes and night sweats. Veozah blocks the chemical NKB,...
It's the "single biggest obstacle to long-term weight loss," Schwartz said. Related: Invisible nerve-cell superhighway allows fat cells to 'talk' to the brain — and it may promote obesity The hypothalamus is a key brain structure involved in controling appetite. It sits above the pituitary...
