1. ENDOCRINE SYSTEM CHEMICAL CO-ORDINATION SYSTEM
INTEGRATE NUMEROUS PHYSIOLOGICAL ACTIVITIES
IT CONSISTS OF A NUMBER OF GLANDS CALLED ENDOCRINE GLANDS

3. HORMONES
THE SECRETIONS OF ENDOCRINE GLANDS(DUCTLESS GLANDS) COLLECTIVELY KNOWN AS HORMONES.

4. ENDOCRINE GLANDS FOUND IN HUMAN BODY
THYROID
PARATHYROID
THYMUS PINEAL BODY, PANCREAS,ADRENALS,PITUITARY AND GONADS.

6. THYROID THIS GLAND LIES AT THE JUNCTION OF THE LARYNX AND TRACHEA.
HORMONES SECRETED BY THIS GLAND IS THYROXINE(AN IODINATED AMINOACID) AND CALCITONIN.
OVER SECRETION OR HYPERTHYROIDISM CAUSES THE DISEASE EXOPHTHALMIC GOITRE.
DEFICENCY OF IODINE IN THE DIET CAUSES ENLARGEMENT OF THE THYROID.THIS CONDITION IS CALLED SIMPLE GOITRE.
HYPROTHYROIDISM DURING INFANCY RESULTS AN IDIOCY AND DWARFISM. THIS DISORDER IS CALLED CRETINISM.
HYPOTHYROIDISM IN ADULT CAUSE MYXOEDEMA.

7. Goiter
SIMPLE GOITRE
EXOPHTHALMIC GOITRE

8. CRETINISM
MYXOEDEMA

9. PARATHYROID THESE ARE FOUR SMALL GLANDS ASSOCIATED WITH THE THYROID.
HORMONE-PARATHORMONE, WHICH IS INVOLVED IN THE REGULATION OF CALCIUM,MAGESIUM AND PHOSPHORUS CONTENTS OF THE BLOOD.
DEFICIENCY-TETANY(THE CALCIUM CONTENT OF BLOOD FALLS BELOW NORMAL)

10. THYMUS IT LIES ABOUT THE HEART UNDER THE BREAST BONE.
HORMONE-THYMOSIN.
INVOLVED IN THE PRODUCTION OF ANTIBODIES LEADING TO IMMUNITY.

12. PINEAL BODY
IT IS A SMALL GLAND LYING ON THE UPPER SURFACE OF THE BRAIN.
HORMONE-MELATONINE
IT CONTROLS REPRODUCTION AND DELAYS SEXUAL MATURITY.

14. PANCREAS THIS GLAND IS BOTH ENDOCRINE AND EXOCRINE.
ENDOCRINE PORTION-GROUP OF CELLS CALLED ISLETS OF LANGERHANS.
TWO TYPES OF CELLS-ALPHA AND BETA.
HORMONE BY ALPHA CELLS-GLUCAGONE.
HORMONE BY BETA CELLS-INSULIN.
THESE HORMONES MAINTAIN CONSTANT BLOOD GLUCOSE LEVELS.

16. HORMONES
INSULIN
WHEN THERE IS A RISE IN BLOOD GLUCOSE LEVEL, THIS HORMONE PROMOT CONVERTION OF GLUCOSE INTO GLYCOGEN.
DEFICIENCY-DIABETES MELLITUS.
GLUCAGONE
WHEN THERE IS A RISE IN BLOOD SUGAR, GLUCAGONE HELPS THE CONVERSTION OF GLYCOGEN TO GLUCOSE WHICH INCREASES THE BLOOD SUGAR LEVEL.

18. ADRENAL LOCATED ON TOP OF EACH KIDNEY.
EACH GLAND IS COMPOSED OF AN OUTER CORTEX AND AN INNER MEDULLA.
THEY ARE TREATED AS SEPARATE ENDOCRINE GLANDS.

20. HORMONES ADRENAL CORTEX CORTISOL CORTISONE ALDOSTERONE
SEX HORMONES LIKE OESTROGEN,PROGESTERONE,ANDROGEN
(VERY SMALL AMOUNT)
ADRENAL MEDULLA
ADRENALIN(EMERGENCY HORMONE)
NORADRENALIN

22. PITUITARY THIS IS THE SMALL GLAND LYING AT THE BASE OF THE BRAIN.
THIS GLAND CONSISTS OF AN ANTERIOR LOBE AND A POSTERIOR LOBE.
THESE LOBES ARE DIFFERENT ENDOCRINE GLANDS.
ANTERIOR LOBE SECRETE A NUMBER OF HORMONES.

24. GROWTH HORMONE (SOMATO TROPHIC HORMONE)
ANTERIOR LOBE
DEFICIENCY IN CHILDHOOD RESULTS IN DWARFISM.
OVER SECRETION OF THE HORMONE DURING CHILDHOOD-GIGANTISM.
IN ADULTHOOD-ACROMEGALY.
OTHER HORMONES ARE TSH.
ACTH
GTH
POSTEIOR LOBE
ASSOCIATED WITH THIS LOBE THERE ARE TWO HORMONE.
OXYTOCIN & VASOPRESSIN (ADH)
DEFICIENCY OF ADH-DIABETES INCIPIDUS.

26. HYPOTHALAMUS
IT IS THE PART OF THE BRAIN IMMEDIATELY ABOVE THE PITUITARY GLAND.
THIS GLAND CONTROL OVER PITUITARY,HAS A CENTRAL ROLE IN HORMONAL ACTIVITIES.
HORMONES- RELEASING HORMONE, OXYTOSIN & VASOPRESSIN ( ADH )
DEFICIENCY IN ADH- DIABETES INSIPIDUS .
OXYTOSIN HELPS TO CONTRACT UTEROUS A CHILD’S BIRTH.

29. GONADS GONADS ARE PRIMARLY CONCERNED WITH THE PRODUCTION OF GAMETES.
THEY ALSO PRODUCE HORMONES CALLED SEX HORMONES.
THEY INFLUENCE THE DEVOLEPEMENT OF APPEARANCE OF SECONDRY SEXUAL CHARACTERS.
FEMALE SEX HORMONES-OESTROGEN & PROGESTERONE.
MALE SEX HORMONES-ANDROGENS
TESTOSTERONE AND ANDROSTERONS ARE THE TWO ANDROGENS SECRETED BY THE TESTES.
