3. This is a picture of - a-bl-film- -- ------it is stained with – Leishman’s stain- ---cells with bilobed nuclei called--esinophils---------- and increase in number during – allergic conditions and parasitic infestation

4. a-this blood film shows 2 granular cells called neutrophils -- b- this type constitute -60-75 %of WBC, their nuclei are--multilobulated------ c- the film shows also large number of RBCs-------- - which has normal count about-5-5.5millions in males and 4.5—5 millions----- in females

5. 1-Enumerate layers of wall of blood vessles -- tunica intima, --tunica media –and –tunica adventitia 2-compare between ( Medium sized Artery and ( medium sized Vein

6. This is a section of –skeletal muscle it shows-multiple peripheral--- nuclei

7. This is section of – cardiac muscle cells it shows- single and - central —nuclei cells are—branched– and—connected by --- intercalated discs

8. This is a drawing of a-skeletal muscle cell it contains multiple and- peripheral- ------- nuclei, it’s cytoplasm is filled with myo-fibrils it’s functional unit is the-- sarcomere -which extends between ---two-- --z-lines--------------

9. Copyright © 2004 Pearson Education, Inc., publishing as Benjamin Cummings Name this structure –the neuron----------- it is formed of -cell-body,-axon---and - dendrites--the structure at the arrows is covered by-myelin sheath and –neurolemal sheath

10. Enumerate structural adaptation of small intestin to its functions ????  Increase surface area for absorption by → intestinal villi.  Minute holes → openings of intestinal crypts.  Circular permanent folds “plica circularis”.  columnar absorbing cells with  Extensive microvilli

11. Pancreas is an -- endocrine and exocrine gland mention main function of each part??? 99% of tissue 1-Islets of Langerhans secrete : A cells- glucagon B cells- insulin D cells- somatostatin F cells- pancreatic polypeptide 2-Pancreatic acini secrete: Digestive enzymes Responds to eating or fasting

12. Which of the following cells is not found in epithelium of the intestinal villi ?? a- columnar absorbing cells. b- chondrocytes. C- goblet cells. D- entero-endocrine cells. e- all of the above.

13. Regarding neuroglial cells, one of the following is wrong------- re part of the nervous system A- Are part of the nervous system B- Specifically demonstrated by silver stain C- show important supportive function D- are specific motor or sensory in function.

14. What is this organ --- the pancrease- --- Name the structure pointed by the arrow--- islets of langerhans- ---- its main secretory product is- ---- insulin

15. The liver has exocrine function as secretion of bile and endocrine function as senthesis of plasma proteins all it’s functions are done the same type of cells called– hepatocytes--

16. The functional unit of the kidney is the— nephron— --enumerate components of nephrons-renal Malpighian corpuscles, loop of Henle,PCTand DCTs. Mention components of juxta glomerular apparatus and its function—macula densa, juxta glomerular cells and lacis cells it’s function is control of blood pressure and secretion of erethropoitin

17. The liver has both –exocrine ---and –endocrine functions which are done by the ----hepatocytes-------- its main functions are: ------------------------------------------------- 1-Endocrine function : secretion of plasma proteins----- 2-Metabolism of carbohydrates, proteins and fats------ 3- Exocrine function :Secretion of bile salts------------------ 4- Detoxication of drugs and toxins

18. Figure 24.20a, b Name this organ- -the liver- ------------- its functional unit is the --- hepatocytes ----- Mention its main functions 1- 2- 3-

19. This is a drawing of ---skeletal----- muscle it is formed of –cylindrical,striated- cells with -multiple-- and—peripheral - nuclei,it’s functional unit is the-sarcomere- which extends between two --z-lines-------

20. This is a drawing of a-skeletal muscle cell it contains multiple and- peripheral- ------- nuclei, it’s cytoplasm is filled with myo-fibrils it’s functional unit is the-- sarcomere -which extends between ---two-- --z-lines--------------

21. Name four types of blood elements in this drawing-- RBCs - monocytes - lymphocytes -- bl-platelets what are types of the cells at the arrows -monocyte---- and --- lymphocyte -------------------

22. White blood cells are the only true cells in blood a- what is the normal leucocytic count – 4- 11000/mm b- in a table form compare between esinophils and basophils c- mention main functions of neutrophils
