The amygdala triggers hypothalamus to bring messages through sympathetic centers in the spinal cord which then get to the middle of the adrenal gland called adrenal medulla‚ and release hormone 2 called adrenalin (epinephrine) and norepinephrine (also known as noradrenaline) (Lightman‚ S. 2008). Adrenaline and noradrenalin are chemicals that released into the blood stream by nerve endings of the

Explain the mechanism of communication‚ control‚ and integration in the endocrine system. The Endocrine systems mechanism of communication is sending messages from the cells of the endocrine and nervous system to the cells in other systems by releasing hormones. The Endocrine systems control feature is part of negative feedback because it

The endocrine system works with the nervous system to maintain homeostasis. The endocrine system secretes hormones in the human body‚ which are produced in endocrine glands and are released into the bloodstream to travel to the its specific target cell‚ tissue‚ or organ. Exocrine glands produce chemicals that are discharged into the surroundings. Hormones can either produce short-lived responses or long-term responses. An example of a short-lived response is when adrenaline (epinephrine)causes the

Blood Water Homeostasis or Osmoregulation Osmoregulation is the process by which the body regulated the osmotic pressure of any organism’s fluids in order to keep the homeostasis of the organisms’ water level constant. Therefore osmoregulation is used to keep the bodily fluid from being too diluted or too concentrated. An osmotic pressure is used to measure the ability of water to move from one solution to another solution through osmosis. Osmotic pressure refers to tendency for a liquid solution
