During the fight-or-flight response, the hypothalamus sends nerve impulses to the sympathetic division of the autonomic nervous system, which quickly mobilizes the body's resources for immediate physical activity. This is the short and quick reaction to a stressor. The second stage is called resistance reaction wherein the hypothalamus releases hormones which are longer lasting. These hormones are are corticotrophin-releasing hormone (CRH), growth hormone-releasing hormone (GHRH), and thyrotropin-releasing hormone (TRH).

∙ 7y agoThe hypothalamus controls the autonomic functions of the peripheral nervous system (PNS). It helps maintain homeostatic functions. It would (and should) increase sweating to cool the skin and lower the fever.Directionally, the hypothalamus is inferior to the thalamus. It is posterior to the optic chiasm and bordered on the sides by the temporal lobes and optic tracts.

How is the brain directly in control of changing body temperature?
The Hypothalamus, its like your body's own thermostat, located at the brain. It makes sure your body is 98.6 degrees Fahrenheit or 37 degrees Celsius. So, when you have fever that's when you know your body temperature is not normal.
What part of the brain maybe responsible for the intermittent fever?
A fever is the elevation of the bodyÕs temperature usually it is indicative of an illness in the body. The part of the brain that regulates the temperature is in the hypothalamus.
What is the role of the hypothalamus in obesity?
The hypothalamus is a small portion of the brain that is responsible to metabolic processes; it controls hunger and thirst along with body temperature etc. If the hypothalamus were to become disrupted or damaged, signals from your stomach may become misinterpreted, making one think they are hungry when they are not. The hypothalamus also responds to stress. In order for one to cope with large amounts of stress, the hypothalamus make you feel hungry. There is a fairly large paper written by G. C. Kennedy about this topic going into great detail. Refer to the URL in the link below.
The region of the brain that recognizes hunger is the?
hypothalamus. It plays a key role in regulating appetite and satiety by responding to signals from the body, such as hormone levels and nutrient availability. Activation of certain areas within the hypothalamus can stimulate hunger or signal feelings of fullness.
What is the storehouse for the hormones produced by the hypothalamus of the brain?
The Posterior Lobe of Pituitary and the HypothalamusThe posterior lobe, so far as is known, does not make any of its own hormones, but serves as a storehouse for two hormones manufactured by the hypothalamus . The hypothalamus, apart from having a role in controlling the body's autonomic nervous system, also functions as an endocrine gland, secreting its own hormones, and as a connecting link between the brain's cerebral cortex and the pituitary gland. The posterior lobe of the pituitary releases the two hormones it receives from the hypothalamus, called vasopressin and oxytocin , into the bloodstream. Vasopressin plays a role in the fluid balance of the body; oxytocin is thought to pace the onset and progress of labor during childbirth.
What role does the hypothalamus play in a fever?
Among the many functions of the hypothalamus is temperature regulation of the body. So, if a person has a fever, then the hypothalamus will try to bring the body temperature back to normal.
The thermoregulatory control center or thermostat that regulates the body's response to changes in temperature such as during a fever is located in the?
hypothalamus
How fever can caused increased intracranial pressure?
because fever effect hypothalamus that control fever in the brain
What are The circulating substances that affect the hypothalamus and initiate fever?
Pyrogens
Where is one of the pleasure centers found in the brain?
Hypothalamus

Can brain tumors cause low grade fever?
With the hypothalamus governing as our body thermometer, yes it can cause fever if it's tumorous or of there's another growth pressing against it.
The circulating substances that affect the hypothalamus and initiate fever are?
Cytokines such as interleukin-1, interleukin-6, and tumor necrosis factor-alpha are the main circulating substances that affect the hypothalamus and initiate fever by increasing the hypothalamic set point for body temperature. These cytokines are released in response to pathogens or inflammation in the body.
How is fever generated?
Leukocytes and macrophages exposed to foreign substances secrete pyrogens such as interleukin-1, leading to the increased production of prostaglandins in the hypothalamus. These prostaglandins inhibit warm temperature-sensing neurons within the hypothalamus. The firing of cold temperature-sensing neurons hence increases to increase the body temperature resulting in fever.
What structure in the brain plays a role in drives associated with survival of the individual and the species?
The Hypothalamus
Does the hypothalmus regulate body temperature?
The hypothalamus does play a role in regulating body temperature
