Which cytokine released by macrophages acts on the hypothalamus to raise the body temperature during fever?
The cytokine released by macrophages that acts on the hypothalamus to raise body temperature during fever is interleukin-1 (IL-1). IL-1 stimulates the hypothalamus to produce prostaglandins, which then trigger an increase in body temperature. This response is part of the body's immune reaction to infection or inflammation.

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.
ADH is produced by cells within the?
ADH (antidiuretic hormone), also known as vasopressin, is produced by cells within the hypothalamus and released by the pituitary gland in response to changes in blood osmolality.
How does hypothalamus warm up your body?
Hypothalamus plays the main role in homeostasis. Homeostasis is the regulation of the activities and reactions that take place in the human body. Hence, it is true to say that hypothalamus is responsible for maintaining the temperature in the body. This is done by dilating the blood capillaries when the temperature in the body exceeds the optimum temperature. By dilating the capillaries, heat can be released out to the surroundings more easily. In A+LS False
What are chemicals released by injured tissue cells and bacteria causing resetting of the thermostat?
These chemicals are called pyrogens, which stimulate the hypothalamus in the brain to reset the body's temperature set point higher, resulting in fever. Pyrogens can be released by various sources like injured tissue cells, bacteria, or other pathogens, signaling the body to increase its temperature as a response to infection or injury.
How do releasing hormones of the hypothalamus connect the nervous and endocrine system?
Hypothalamus controls the posterior pituitary gland which is connected with axons. Thus the hypothalamus synthesizes oxytocin and anti-diuretic hormones which are then packaged in secretory vesicles and moved to axons. When axon terminals are triggered, the hormones are released in the capillaries of posterior pituitary.
What is the definition of the word cytokine?
A cytokine is a regulatory protein released by a cell in the immune system. Cytokines act as intercellular mediators when the body is generating an immune response.
DO Lymphokines attack macrophages?
Lymphokines do not attack macrophages. Lymphokines are molecules released by activated T cells to regulate the immune response, while macrophages are immune cells that engulf and digest pathogens. However, some lymphokines can stimulate macrophages to be more effective in phagocytosis and killing of pathogens.
What are released by to cells to protect other cells by interfering with the ability to the virus to reproduce as it moves from cell to cell?
Interferons (IFNs), which are a type of cytokine.
The circulating substances that affect the hypothalamus and initiate fever are?

These cytokines are released in response to pathogens or inflammation in the body.
A hormone that is released into the bloodstream in response to physical or mental stress?
a hormone known as KAP is released by hypothalamus when insane
Which hormone is secreted by the hypothalamus and stored in and released by the pituitary gland?
antidiuretic hormone (ADH)
What is the function of the infundibulum?
The infundibulum is a funnel-shaped structure in the brain that connects the pituitary gland to the hypothalamus. Its function is to allow hormones produced by the hypothalamus to be transported and released into the pituitary gland for further regulation of hormone production and secretion.
ADH is produced by cells within the?
ADH (antidiuretic hormone), also known as vasopressin, is produced by cells within the hypothalamus and released by the pituitary gland in response to changes in blood osmolality.

What is the site of regulation of water balance and body temperature?
Changes in body temp are recognised by the hypothalamus in the brain. An increase in body temp leads to vasodilation of blood vessels and thus more heat radiated from the skin. Also stimulates the production of sweat and thus heat loss by evaporation. A decrease in temp results in vasoconstiction of blood vessels and thus heat retention. Water balance is also recognised by the hypothamus but is controlled by the kidneys. ADH is released from the pituritary gland which increases water reabsorption in the kindeys whilst Aldolsterone is released from the adrenal cortex (gland located above kidney) which increases the absorption of Na+ ions which causes water to follow passively by osmosis.
