2. Anatomical structure of the pancreas
The pancreas is a member of an extended there after the first part of the small intestine, and is composed of lobes of soft texture.
Consists of the exocrine glands and internal secretion glands, or the so-called islands of Langerhans

4. Location
The pancreas is a gland located deep in the abdomen between the stomach and the spine (backbone). The liver, intestine, and other organs surround the pancreas.

5. The islands of Langer Hans
A clusters of adjacent cells are distributed randomly and lying between the cells of internal secretion of the pancreas, and the number of islands nearly a million in humans.  
All the islands of Langer Hans consists of a cluster of polygonal cells in small groups around the capillaries which are a dense network surrounding each island.
In addition, the related ends of nerve fibers and Asambthawayp Albarracmbthawayp.

7. Islands of Langerhans
There are three types of cells   1-cell-loving base and are called beta cells Beta Cells    Produce the hormone insulin, which are the bulk of the islets of Langer Hans about 60%
2-Cells love to dye and acid called Alpha Cells     Secrete the hormone glucagon, represent about 25% of the islets of Langer Hans.
3-Delta cells     Produce the hormone somatostatin, which represents about 10% of the islets of Langer Hans.

9. Hormone insulin
Secreted when increasing the level of blood sugar (Hyper glycemia(
Facilitate the absorption of the cells to glucose
Hormone builders
)fats, proteins, nucleic acids(

10. Synthesis of the hormone insulin
DNA
RNA
mRNA
Preprohormone
Prohormone
Insulin

11. Imbalance resulting from the secretion of insulin
Increase the secretion of insulin Disease heap of sugar
Lack of insulin secretion Diabetes

12. first type Secondary type
Non-insulin dependent Diabetes late
Insulin-dependent Diabetes early
Shortage in the number of insulin receptors in target cells
Reduced amount of insulin as a result of the crash of beta cells to either viral infection or otherwise
Occurs with age
Occurs in children
Not eating sugars / snacking
Insulin injections / snacking at intervals

13. Hormone glucagon
Secreted when the level of lack of blood sugar (Hypo glycemia(
Runs counter to the hormone insulin (Antagonism(
Hormone HDMI  - Analysis of glycogen Glycogenolysis
- Composition of glucose from sources other than carbohydrate Gluconeogesis - Increase the formation of urea  - Inhibition of fatty acid

14. Molecular structure of the hormone glucagon
- Consists of 29 amino acid.
The molecular weight of 3450.
- Spiral shape.

15. Balance blood sugar
Hyper glycemia
Hypo glycemia

16. Hormones affect glucose levels
Hormones Insulin
Hormones Glucagon
Hormones Epinepherine
Hormones Cortisol
Growth hormone
Thyroid hormone

17. Third: The hormone adrenaline
- Creates in the adrenal gland, spinal cord   - Secreted when the pressure and Sports - Works on the composition of glucose from sources other than carbohydrate   - Reduces the secretion of insulin / glucagon secretion increases - Increases lipolysis

18. IV: cortisol
Secreted by the adrenal cortex Increases the proportion of blood glucose by:  - Composition of glucose from sources other than carbohydrate.  - Analysis of glycogen and fat and protein.  - Absorption of glucose in the tissues except the brain.

19. V : Growth Hormone Secreted by the anterior lobe of the pituitary.
Its functions: 1-Secretion of IGF 2- Building protein 3- Lipolysis in adipose tissue 4-Absorption of glucose in the muscles

20. The organization of the secretion of growth hormone
a hormone secreted from GHRH.
Hypothalamus Increasing the amino acids. Lack of fatty acids. lack of blood sugar. hormone somatostatin.

21. VI: thyroid hormones
Secrete thyroid hormones T3 / T4 by the hormone TSH
Increase the secretion of growth hormone
As well as glucagon is excreted by the hormone TRH
