Hypothalamus+Researcher+2

Put your name here:Ilyssa Weiner

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: · A picture(s) of the gland showing its shape and location in the human body. (It is located in the brain) __ [] __
 * Task:**

· The hormone(s) produced by your endocrine gland. **Thyrotropin-releasing hormone (TRH)** **Gonadotropin-releasing hormone (GnRH)** **Growth hormone-releasing hormone (GHRH)** **Corticotropin-releasing hormone (CRH)** **Somatostatin** **Dopamine** __ [] __
 * These hormones are released into the capillaries of the blood and travel immediately (in portal veins) to second capillary bed in anterior lobe of of pituitary. **
 * [] **

· The stimulus that tells your gland to produce hormones. __**[]**__ __**Hypothalamic Disorder**__
 * When there are fewer glucocorticoids secreted by the adrenal cortex, this causes the hypothalamus to produce CRH. CRH then travels to the pituitary gland and stimulates it to make more adrenocorticotropic hormones, increasing adrenal secretion. The Hypothalamus sends signals to the pituitary gland to tell it to produce hormones that regulate body functions.**

 * Function of hypothalamus: Produces hormones for stimulating adrenal glands/ Maintaining homeostasis/ Functioning the brain (Processing center in human body)/ Regulates thirst, hunger, body temperature, water balance, and blood pressure/ Links nervous system to endocrines system/ Controls emotions and behavior (including sexual behavior ;) )**
 * []#**
 * []**
 * Causes: Malnutrition, Trauma, Anorexia, Tumors**
 * Symptoms: Headaches and vision problems, hypothyroidism problems (**Those symptoms are Constipation, Fatigue, Weight Gain, Body hair loss, Hoarse voice, Impotence, and Disturbances in menstrual cycle**), Adrenal Dysfuncation, and Altered Body Temperature**
 * []**

· The control mechanism that tells your gland to stop producing hormones.
 * The Hypothalamus sends signals to the rest of the glands (including the pituitary gland) to stop producing hormones.**

· The function(s) of the hormone(s) produced by your gland. 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.** **TRH function:** **Stimulates the secretion of thyroid-stimulating hormones from the pituitary glans** **Subserves other central nervous system activities** **(Possibly) Controls body temperature**

**GnRH function:**
 * Stimulates the synthesis and release of the two pituitary gonadotropins: luteinizing hormone (LH) and follicle-stimulating hormone (FSH) **
 * GHRH function: **
 * Stimulates growth **

**Stimulates secretion of corticotropin in the pituitary** **Stimulates synthesis of corticotropin in corticotropin-producing cells (corticotrophs) of the anterior lobe of the pituitary gland.** **Directs body's response to all forms of stress** **Keeps T-cells from mounting immune attack against fetus ([])**
 * CRH function: **

**Somotostatin function:** **Blocks secretion of GH, insulin, glucagon, and other hormones** **Inhibits release of [|prolactin] (PRL) from anterior lobe of the pituitary.** **[]** __ **Boundaries of Hypothalamus** __ **Superior-Hypothalamic sulcus** **Inferior- Optic chiasma, tuber cirumium, mammillary bodies and median eminance ** **Anterior-Lamina terminalis**
 * Inhibits many functions of Gastrointestinal tract (includes secretion of stomach acid, the secretion of pancreatic enzymes, and process of intestinal absorption.) **
 * [] **
 * Dopamine function: **
 * Posterior – Midbrain tegmentum **
 * Medial – Third ventricle **
 * Lateral – Internal capsule **
