1. SKIN & FASCIA

2. INTRODUCTION

3. 3

4. Types of Skin Thick skin Thin skin

5. Mucocutaneous junction It is the place where the skin continues with the mucous membrane e.g : Lips & eyelids

6. Functions of skin Protection Acts as a Barrier Temperature regulation Sensory Excretory Synthesize of Vitamin D

7. STRUCTURE OF SKIN

8. Epidermal Cells and Layers Figure 5.3 11

9. Epidermis

10. Dermis

11. Layers of dermis Papillary layer Reticular layer Cleavage line/ langer’s line Wrinkle’s in the skin

12. Dermatome The area of skin supplied by a single spinal segment called as Dermatome.

13. Hypodermis It is the deepest layer and it contains adipose tissues and large vessels that supply and drain the dermis.

14. Appendages of skin

15. Hair

16. Arrector Pilli Muscle

17. Pilosebaceous unit

28. Fascia DEFINITION It is a fibrous tissue network in the form of sheet or flat band.

29. Location Below the surface of the skin, covering and separating the muscles, organs and other tissues.

30. Function of fascia Sliding and gliding surface for muscles to reduce friction. Suspends the organs in anatomical position. Transmits the movement in to the bones to which they are attached.

31. Types of fascia Superficial fascia Deep fascia Subserous fascia

32. Superficial fascia Location Composition Contents Panniculus adiposus Panniculus carnosus Regional difference - Distinct - Very thin -Very thick -Stratification -Superficial fascia without fat

33. Superficial layer in abdomen

34. Deep fascia Distribution Best defined Ill defined

35. Palmar aponeurosis

36. FASCIA LATA

37. Modification of deep fascia Intermuscular septa Coverings for muscles Coverings for nerves Coverings for glands Sheath around large arteries Aponeurosis Retinacula

38. Modification of deep fascia in different regions Neck Back Upper limb Lower limb
