Anatomy and physiology

(TUTORIAL 5)

ANSWER;

a)Hair b)Epidermis c)Dermis d)Hair follicle e)Subcutaneous Tissue f)Sweat Gland g)Arteriole

  1. 4 Types of epidermis layer is: -Keratinocytes -Melanocytes -Langerhans -Merkel Keratinocytes -Produce a water repellent sealant ~Decreases water entry and loss

~Inhibit entry of foreign materials Melanocytes -8% of epidermis ~Produces the pigment melanin [Contributes to skin color] [Absorb damage UV light] [Increases with expocure to sunlight] Langerhan Cell [Invades and destroy microbes Merkel cell -They detact the touch sensation 3)5 layer of epidermis -Stratum corneum -stratum lucidum -stratum granulosum -stratum spinosum -stratum basale

  1. Yellow- Jaundice Orange-Excessive intake of carotene Pale/White-Inability of melanocytes to produce melanin(Albino) Bluish/Purplish- Cyanosis/Melanocytes in the germinative layer secretes melanin -Jaundice -Carotene
  1. 5 function of human skin: -Protection -Cutaneous sensation -Excretion (removal of waste product) -Regulation of temperature -Effect of vasadilatition and vasoconstriction.
