for chemical signaling of target cells. Endocrine glands do not have a duct system and are called ductless glands. These glands release hormones directly into the blood or lymph. These glands include the pituitary gland‚ the pineal gland‚ the hypothalamus‚ the thyroid gland‚ the parathyroid glands‚ the thymus‚ the adrenal glands‚ the ovaries (in females) or testes (in males)‚ and the pancreas. Endocrine glands have a rich blood supply through which hormones travel to reach their target organs.

few functions to combat the outside elements. People cannot make themselves cold as readily as make themselves hot‚ however I will mention both homeostasis functions. When the external temperature decreases‚ a portion of the brain called the hypothalamus detects the drop by means of the blood. To compensate‚ the brain sends chemical and electrical impulses to the muscles. These impulses tell the muscles to begin to contract and relax at very high intervals. This is commonly known as shivering

cells and the interstitial fluid. The result is water leaving the cells to restore the balance. The disruption in the interstitial solution is recognized by neurons called osmoreceptors. These osmoreceptors are located in the region of the anterior hypothalamus. These osmoreceptors send a signal that causes us to drink more water‚ in order to restore the osmotic balance between the cells and surrounding fluid. In the case of pretzel eating‚ if we do not drink more water‚ eventually the excess

Written Assignment 1 1) Identify the organs of the endocrine system‚ including their locations and structures. Hypothalamus: Is located below the thalamus just above the brainstem. Pituitary: Is location within the sella turcica which is a dip in the sphenoid bone. Structures are tropic hormone and neurohypophysis. Thyroid: A) Location: anteriorly‚ above the thyroid glad. B) Structures are the isthmus connecting the two lobe and thyroid follices and network of capillaries Adrenal:

build ups in the production of hormones like adrenalin and cortisol that yields an alteration of heart rate and metabolism to make better performance (Peters‚ M. 2006). Stress reaction is triggered when there is an activation of stressor in the hypothalamus. In this essay the stressor identified is the patient waiting to be seen in a clinic feeling stressed. When patient perceive that they are in frightening or uneasy situation and that they do not have the capacity to deal successfully‚ the neurons
