    4. Characteristics of papillary layer Top part of dermis Projections called dermal papillae Pain receptors Touch receptors Blood vessels

    5. Complications of 3rd degree burn Associated dangers - Dehydration - Electrolyte imbalance - Circulatory shock

    6. Function of sebum Oil made by sebaceous glands - Lubricant for skin - Kills bacteria Most with ducts that empty into hair follicles

    28. Mucous membrane location Body cavities that open to the outside

    29. Where are the three kinds of dermal receptors found? Free nerve endings In dermal papillae Meissner’s corpuscles In dermal papillae. Pacinian corpuscles In reticular layer

    30. Which kind of membrane is all connective tissue
