  1. GENERAL ORGANIZATION SKINDr. Mah Jabeen MuneeraAssistant Professor Department of AnatomyKEMU TERMS, PLANES, POSITIONS

  2. ANATOMICAL POSITION • SIGNIFICANCE

  3. PLANES • MEDIAN • SAGITTAL • CORONAL/ FRONTAL • HORIZONTAL • OBLIQUE

  4. TERMS • ANTERIOR • POSTERIOR • VENTRAL • DORSAL

  5. MEDIAL • LATERAL • SUPERIOR • INFERIOR • CRANIAL • CAUDAL

  6. PROXIMAL • DISTAL • EXTERNAL • INTERNAL • SUPERFISCIAL • DEEP • COMBINED TERMS • IPSILATERAL • CONTRALATERAL

  7. FOR LIMBS • RADIAL • ULNAR • TIBIAL • FIBULAR • PALMAR • PLANTAR

  8. GENEARL ORGANIZATION • CELL- basic unit of structure and function • TISSUE

  9. BASIC TISSUES • Similar structural & functional characteristics • Epithelium • Connective Tissue • Nervous Tissue • Muscular Tissue

  10. ORGAN • SYSTEM • ORGANISM

  11. INTEGUMENTARY SYSTEM • Skin & derivatives • Hair • Nail • Muco-cutaneous junctions • Associated glands • Sweat glands • Sebaceous glands • Mammary glands

  12. Skin covers body surface • ext. auditary meatus • Lat. Surface of ear drum • vestibule of nose

  13. 8% of total body mass • Surface area 2.2m2 • Thickness varies, depending upon age and region

  14. STRUCTURE • Epidermis • Dermis

  15. LAYERS

  16. FUNCTIONS • Self renewing interface • Sensation • Protection • Temperature Regulation • Control of water output • Absorption • Secretion • Excretion • Synthesis of vitamin D • Storage • pH regulation • Repair after trauma • Elasticity; skin lines • Social Communication • Dermatoglyphics

  17. APPEARANCE • Skin lines • Complexion • Thickness • Reddish hue of vascularity • Melanin • Carotene

  18. Distribution of hair • Skin glands • Changes due to maturation, ageing • General state of health

  19. SKIN LINES • TENSION LINES (LANGER’s) • Incision lines • STRETCH MARKS • WRINKLES • DERMATOGLYPHICS • OCCUPATIONAL • FLEXURE LINES; JOINT LINES

  20. SUPERFICIAL FASCIA • Loose connective tissue • Adipose tissue • Distribution varies • Contours • insulation

  21. DEEP FASCIA • Thick connective tissue • Binds superfiscial fascia with underlying tissues • Invests structures; muscles, nerves, blood vessels • Sends partitions

  22. CLINICAL SIGNIFICANCE • Information tells clinician about HOW & WHERE the fluids e.g. pus will track • Lymphatics follow the plane of fascia, knowledge is important in malignancies
