Location- Thymus Gland  The thymus gland is located behind your sternum and in between your lungs.  After puberty the thymus starts to slowly shrink and replaced by fat.

Thymosin  Hormone in the thymus gland that stimulates the development of T Cells.  Throughout childhood, white blood cells called lymphocytes pass throughout the thymus.  Thymosin causes them to be transformed into T cells.  T cells migrate to the lymph nodes (groups of immune system cells) throughout the body.  They aid the immune system in fighting diseases.

Location- Hypothalamus Gland  The hypothalamus gland is located directly under the Thalamus.  It is a portion of the brain that maintains the body’s internal balance.  It is the link between the endocrine and nervous system

Hypothalamic-Releasing Hormone  Hormone that stops and starts the production of other hormones throughout the body.  It stimulates..  Heart rate and blood pressure  Body temperature  Appetite and body weight  Sleep cycles  Production of substances that influence the pituitary gland to release hormones  Glandular secretions of the stomach and intestines of-endocrine-system-by-the-hypothalamus

Diseases- Hypothalamic Disease  Hypothalamic disease is a disease primarily of the hypothalamus  A physical injury to the head that impacts the hypothalamus is one of the most common causes of hypothalamic disease  Hypothalamic diseases can include appetite and sleep disorders, but because the hypothalamus affects so many different parts of the endocrine system, it can be hard to pinpoint whether the root cause of the disorder is actually related to another gland. 

Diseases- DiGeorge Disease  DiGeorge syndrome occurs in children born without a thymus gland.  As a result, there is a lack of thymosin production. Thymosin is needed to stimulate the differentiation of T lymphocytes.  Symptoms:  Little or no immune response, inability to resist bacterial, viral or fungal infection, a lack of cancer cell surveillance, inability to reject foreign tissues, high and Broad nasal bridge and Downturned mouth

Fun Facts!  The thymus got its name because it resembles a thyme leaf.  The hypothalamus regulates hunger and thirst while playing a substantial role in the body's overall metabolic rates, therefore people have targeted it to help with long lasting weight loss.  Angelo M. DiGeorge was known for his studies on autosomal dominant immunodeficiency, DiGeorge Syndrome.  The thymus gland shrinks with age and becomes almost non-existent. It becomes almost the size of a pea.
