Hypothalamus+Researcher+1

Put your name here:Lamaria Edwards

You and your group will be responsible for putting together a defensive presentation of an endocrine gland. You and your group will be giving this presentation during class. Your presentation must include:
 * Task:**

· A picture(s) of the gland showing its shape and location in the human body. · The hormone(s) produced by your endocrine gland. The hypothalamus is located in the [|limbic system] of the brain, an area of the brain that controls emotions and behavior. So it makes sense that the hypothalamus gland controls our emotions and behaviors, including sexual behavior. Another key activity of the hypothalamus is secreting hormones that support the normal function of the [|pituitary gland]. Other fundamental tasks, performed by the hypothalamus, include regulating body temperature, appetite, digestion, circulation and sleep. Additionally, the hypothalamus gland controls critical metabolic activities, helping us maintain healthy fluid levels and properly metabolize fats and sugars. The major hormones secreted by the hypothalamus are corticotrophin releasing hormone (CRH), thyroid stimulating hormone releasing hormone (TRH), follicle stimulating hormone releasing hormone (FSHRH), luteinizing hormone releasing hormone (LRH), and growth hormone releasing hormone (GHRH). CRH targets the adrenal glands. It triggers the adrenals to release adrenocorticotropic hormone (ACTH). ACTH functions to synthesize and release corticosteroids. TRH targets the thyroid where it functions to synthesize and release the thyroid hormones T3 and T4. FSH targets the ovaries and the testes where it enables the maturation of the ovum and of spermatozoa. LRH also targets the ovaries and the testes, and its receptors are in cells which promote ovulation and increase progesterone synthesis and release. GHRH targets the anterior pituitary to release **[|growth hormones]** to most body tissues, increase protein synthesis, and increase blood glucose.

What are the target organs/cells and how does the message carried by the hormone help maintain homeostasis. **This is probably the most important part of your presentation.** > In response to stimuli such as stress, pain and emotions, the hypothalamus can exert effects on the anterior and posterior pituitary gland in order to respond rapidly to environmental change as well as to feedback from internal systems.
 * It controls the autonomic nervous system, acts with the limbic system to regulate emotional and behavioural patterns, regulates eating and drinking, controls body temperature and regulates diurnal rhythms. It also controls pituitary gland secretions.
 * The hypothalamus receives input from the external and internal environment as well as having its own receptors. It receives stimuli from the somatic and visceral sense organs. These inputs travel via the medulla oblongata and reach the hypothalamus through innervation by fibres producing dopamine, adrenaline, noradrenaline, serotonin and acetylcholine as well as fibres releasing neuropeptides such as enkephalins, NPY, neurotensin, dynorphins and endorphins.
 * The release of hormones from the pituitary is therefore subject to many different stimuli from 'higher centres' acting on the hypothalamus.
