The powerpoint presentation on the endocrine System. It describes the endocrine system of the human body and hormones.

1. LECTURE TOPIC:
ENDOCRINE SYSTEM.

2. ENDOCRINE SYSTEM
 it is a system of INTERNAL SECRETING GLANDS.
 Their secretions are called HORMONES.
 Hormones are biologically active substances,
responsible for function of different organs

3. 1). CENTRAL GLANDS:
- Hypothalamus
- Pituitary G
- Pineal gland

4. 2) PERIPHERAL GLANDS:
-Thyroid
-Parathyroid
-Adrenal
-Gonads
-Pancreas
-Thymus.

5. HYPOTHALAMUS
Located in the brain just below the thalamus
Functions as part of both the nervous system and
the endocrine system

6. Hypothalamus
Pituitary
Gland
Pineal
gland

7. PITUITARY GLAND
Located in the brain at the end of the stalk from
the hypothalamus.

9. POSTERIOR PITUTARY
• The posterior pituitary gland secretes two hormones
that are produced in the hypothalamus.
Antidiuretic hormone (ADH)
Oxytocin

10. PINEAL GLAND
Located between the two lobes of the thalamus

11. THYROID GLAND
An irregularly shaped gland that has two lobes connected
by a thin bridge in between (the isthmus)
Located in the neck on either side of the trachea and
across its anterior surface

13. PARATHYROID GLANDS
 Four tiny glands
 Located on the posterior surface of the
thyroid gland, two on each lobe

14. THYMUS GLAND
A pink gland with two lobes located in the thoracic cavity
posterior to the sternum
Large during childhood and puberty but shrinks during
adulthood

15. PANCREAS
 Located posterior to the stomach
 In C – like duodenum

17. ADRENAL GLANDS
Paired, triangular glands over the superior end of each
kidney.
Each gland has an outer layer (cortex) and an inner layer
(medulla).
Each layer functions independently of the other and
secretes its own hormones.

19. OVARIES
Small, egg-shaped glands located in the pelvic cavity
Function as part of both the female reproductive
system and the endocrine system

20. TESTES
Male genital glands, located outside the body in
the scrotum
