it is usefull for biotech engineering students

•EPITHELIAL TISSUE
•CONNECTIVE TISSUE
•NERVOUS TISSUE
•MUSCULAR TISSUE

4. STRUCTURE OF EPITHELIAL TISSUE

5. EPITHELIAL TISSUE
•EPITHELIAL TISSUE FORMS A MULTITUDE OF
BIOLOGICAL BARRIER -
THE CENTRAL FUNCTION OF EPITHELIAL IS AN
ORGANISM.
•EPITHELIAL TISSUE
PRODUCE NITROGEN OXIDE (NO),WHICH LEADS TO
A REDUCTION IN THE SMOOTH MUSCLE TONE
SURROUNDING BLOOD VESSELS AND THUS TO
A INCREASE IN FLOW.
t

6. FUNCTION OF EPITHELIAL TISSUE
• EPITHELIAL TISSUE HAS A NUMBER OF FUNCTIONS
,WHICH INCLUDE
PROTECTION AGAINST ABRASION, RADIATION DAMAGE,
CHEMICAL
STRESS AND INVASION BY PATHOGENS.
•THE SKIN OF MOST MAMMALS CONTAINS LAYERS OF
THICK KERATINIZED DEAD EPITHELIAL CELLS
PROTECTING THEM AGAINST WATER LOSS AND OTHER

7. STRUCTURE OF CONNECTIVE TISSUE

8. CONNECTIVE TISSUE
• CONNECTIVE TISSUE OCCURS ALL OVER THE
HUMAN BODY AND IN MANY TYPES.
•CONNECTIVE
TISSUE CELLS INCLUDE LEUKOCYTES ,PLASMA
CELLS, MACROPHAGES AND MAST CELLS.
•THE INDIVIDUAL CONNECTIVE
TISSUE CELLS DEVELOP OUT OF MESENCHYMAL

9. FUNCTION OF CONNECTIVE TISSUE
•IT PROVIDES SURFACE COATINGS IN THE FORM OF
SUPERFICIAL
FASCIA WHICH STORES FAT AND CONSERVES BODY HEAT.
•CONNECTIVE TISSUE HELP IN THE REPAIR OF
INJURIES WHEREBY THE
FIBROBLAST LAY DOWN COLLAGEN FIBERS TO FORM THE
SCAR TISSUE.

10. STRUCTURE OF NERVOUS TISSUE

11. NERVOUS TISSUE
•IT CONSISTS OF NERVE CELLS(NEURONS)AND
NEUROGLIA(SPECIAL NEURAL CONNECTIVE TISSUE
CELLS)AND MAKES THE EXCHANGE OF
INFORMATION WITHIN AN ORGANISM
AND BETWEEN DIFFERENT TISSUES POSSIBLE.
•THE NERVE CELL BODY(SOMA)CONTAINS THE
NUCLEUS AND THE SYNTHESIS APPARATUS, WHICH
PRODUCES THE

12. FUNCTION OF NERVOUS TISSUE
• NERVOUS TISSUE MAKES UP THE NERVOUS SYSTEM.
THE CENTRAL NERVOUS SYSTEM (CNS) IS COMPOSED
OF THE BRAIN AND SPINAL CORD, WHICH COORDINATES
INFORMATION FROM ALL AREAS OF THE BODY AND
SENDS NERVE IMPULSES THAT CONTROL ALL BODILY
MOVEMENTS. THE PERIPHERAL NERVOUS SYSTEM(P N
S) CONSISTS OF PERIPHERAL NERVES THROUGHOUT
THE BODY.
• THE ENTIRE NERVOUS SYSTEM (E N S )CONTROL

13. STRUCTURE OF MUSCULAR TISSUE

14. MUSCULAR TISSUE
• THE CELLULAR ELEMENTS OF MUSCLE TISSUE CAUSE
AN
ACTIVE CONTRACTION.
•THE MAIN PARTS OF MUSCLE FIBER IS THE
MYOFIBRILS. THE
MYOFIBRILS CONTAIN SARCOMERES WHOSE BORDERS
DEFINED BY THEIR Z-DISKS, CONTAIN PARALLEL-
