  3. 3What is the outer layer of the skin called?
    1. Adermis
    2. Bepidermis
    3. Chyperdermis
  4. 4What is the stratum basale ?
    1. Amultiple rows of closely packed, many sided keratinocytes tightly linked by desmosomes
    2. Bmultiple rows of flattened keratinocytes containing darkly staining keratohyalin granules and lipid-rich lamellar bodies – on release these form an hydrophobic, impermeable barrier

  5. 5What is the stratum spinosum?
    1. Asingle layer of columnar keratinocytes resting on a basement membrane: site of production of new keratinocytes
    2. Bmultiple rows of closely packed, many sided keratinocytes tightly linked by desmosomes
    3. Cmultiple rows of clear, flat, dead, keratin-rich keratinocytes; present only in thick skin *ONLY IN THICK SKIN*
  6. 6stratum granulosum?
    1. Amultiple rows of clear, flat, dead, keratin-rich keratinocytes; present only in thick skin *ONLY IN THICK SKIN*

    3. Cmultiple rows of flattened keratinocytes containing darkly staining keratohyalin granules and lipid-rich lamellar bodies – on release these form an hydrophobic, impermeable barrier
