Thyroid

  1. 1. ENDOCRINE SYSTEMTITLE : THYROID
  2. 2. WHAT IS …. THYROIDTHYROID ?THYROID!!!
  3. 3. THYROID•Control metabolism .•One of the largest endocrine system in our body.•Located : Front of the neck the trachea.•Shape : Small butterfly shaped gland with two lobes.•It’s contain of 3 type of hormones.i. T3 ( Triiodothyronine )ii. T4 ( Thyroxin )iii. Calcitonin.
  4. 4. m
  5. 5. IMPORTANT• They would be lacking the supply of energy you would eventually DIE (if <NO> thyroid and hormone replacement)• Thyroidectomy (removal of the thyroid gland), there are hormone replacement therapies.
  6. 6. FUNCTION• Control metabolism. Metabolism is the rate at which all the chemistry of the body works.• Control growth in early life.• Controls how quickly the body uses energy, makes proteins,• Controls how sensitive the body should be to other hormones.
  7. 7. HORMONE (CONT’)• The thyroid gland is controlled by thyroid-stimulating hormone (TSH)• Thyrotropin-releasing hormone (TRH) produced by the hypothalamus• The T3 and T4 are also known as THYROID HORMONES.>T3 - Triiodothyronine>T4 – Thyroxin
  8. 8. HORMONE ( CONT’)• Calcitonin - Produced by para follicular " C" cells a role in calcium homeostasis.• Calcitonin – controlling blood calcium levels to prevent the the hypercalcemia (too much calcium in the blood).• The hormones controlled by anterior pituitary by the elaboration of thyrotropin.
  9. 9. HORMONE ( CONT’)T3 and T4 affect most cells of the body by:• Increasing the basal metabolic rate and heat production.• Regulating metabolism of carbohydrates, proteins and fats• T3 and T4 are synthesized utilizing both iodine and tyrosine.
  10. 10. DEFINITIONHyperthyroidism (overactive thyroid) is a condition in which your thyroidgland produces too much of the hormone thyroxine. Hyperthyroidismcan significantly accelerate your bodys metabolism, causing suddenweight loss, a rapid or irregular heartbeat, sweating, and nervousness orirritability.DEFINITIONHypothyroidism (underactive thyroid) is a condition in which your thyroidgland doesnt produce enough of certain important hormones.It seldom causes symptoms in the early stages, but, over time, untreatedhypothyroidism can cause a number of health problems, such as obesity,joint pain, infertility and heart disease.
  11. 11. CONCLUSION•Located : Front of the neck the trachea.•Shape : Small butterfly shaped gland with two lobes.•Supply of energy required.•It’s contain of 3 type of hormones.i. T3 ( Triiodothyronine )ii. T4 ( Thyroxin )iii. Calcitonin.•The hormones secreted by thyroid gland are controlled by anteriorpituitary by the elaboration of thyrotropin.
  12. 12. we QUESTION, you ANSWER1)Where is the location for the thyroid ? !•Found in the neck, inferior to the thyroid cartilage(ADAM’s apple )2)Will we die if we are without thyroid ? Why ?•YES ! Because thyroid is one of the important system in our body.Its controls the metabolism of our entire body and every cell.3)T3 & T4 are knowns as thyroid hormones.What’s the affect of T3 & T4 for our body.•Increasing the basal metabolic rate and heat production.•Regulate metabolism of carbohydrates, proteins and fats.
  13. 13. THE END… Wahahaha…
  14. 14. Thank You ♥Terima Kasih 谢谢 …どうもありがとう … 감사합니다 ♥
