  1. Thymus & Hypothalamus Joan Daly and Antony Sare HAP Period 5

  2. Overview of the Endocrine System • Instrumental in regulating: • Mood • Growth and development • Tissue function • Metabolism • Sexual function and reproduction • In charge of slow body processes, like cell growth

  3. Specific Glands Thymus Hypothalamus

  4. Location of Glands • Thymus  right next to the heart • Hypothalamus  above the brain stem

  5. Role & Function: Thymus • Controls immune mechanism • Promotes maturation of B-cells and T-cells • Becomes inactive later in life, leading to atrophy • Atrophy is why older people contract more diseases

  6. Role & Function: Hypothalamus • Maintains homeostasis • Contains specialized nuclei to maintain basic psychological functions • Body temperature • Blood pressure • Fluid and electrolyte balance • Digestion • Main cause of involuntary emotional choices

  7. Hormones • Hypothalamus secretes dopamine • Thymus secretes thymosin & thymopoietin thymosin thymopoietin dopamine

  8. Dopamine • Hormone produced in the hypothalamus, also considered to be a neurotransmitter • Affects diverse processes like muscle movement, thinking, emotion, motivation and pleasure • Fun fact: people with Parkinson’s disease have depleted levels of dopamine

  9. Thymosin • Hormone that plays an important role in regulating the immune system • Found in the thymus gland • Two types: • Alpha: play a role in dnatranscription • Beta: operate in the cellular cytoplasm and contribute to cell mobility • Together they function to detect the presence of autoimmune diseases and affect how T cells (germ-killing white blood cells) function

  10. Thymopoeitin • Also released by the thymus • Reside in cell nucleus and help out by maintaining the structural organization of the nuclear envelope • Also regulates the localization of chromosomes in the nuclear membrane • Mutations in thymopoietin result in cardiomyopathy

  11. Myasthenia Gravis • Atype of auto immune disorder (immune system mistakenly attacks healthy tissue) • Body produces antibodies that block the muscle cells from receiving messages (nerve impulses) • Associated with tumors of the thymus • Symptoms: difficult breathing, chewing, climbing stairs, talking… facial paralysis, fatigue, double vision

  12. Hypothalamic Disease • Caused by excessive dietary intake of iron, malnutrition, trauma, or tumors • Symptoms: headaches and vision problems, can increase hypothyroidism problems (affects the hormone production of pituitary and thyroid glands), altered body temperature, inability to control urination, excessive thirst, obesity and emotional disturbance • All depends on the severity of the disease

  15. Concept Check • 1. Describe the main function for the thymus and hypothalamus, and state where each is located. • 2. State the bodily processes dopamine regulates. • 3. Explain the difference between to the two types of thymosin, and what thymosin does. • 4. What is myasthenia gravis and how does it affect the body?
