  1. Nail
  2. Hair follicle
  3. Mucous membrane
  4. Dermis
  5. Papillary layer
  1. a the deep layer of the skin; composed of dense, irregular connective tissue
  2. b the upper dermal region. It is uneven and has peglike projections from its superior surface, called dermal papillae, which indent the epidermis above.
  3. c slightly slanted compound structures. The inner epidermal sheath is composed of epithelial tissue and forms the hair. The outer dermal sheath is actually dermal connective tissue. Dermal region supplies blood vessels to the epidermal portion/reinforces it.
  4. d membrane that forms the linings of body cavities open to the exterior (digestive, respiratory, urinary, and reproductive tracts)
  5. e a scale-like modification of the epidermis that corresponds to the hoof or claw of other animals. Has a free edge, a body(visible attached portion), and a root (embedded in the skin).

5 Multiple choice questions

  1. membrane that lines the fibrous capsule of a synovial joint.
  2. the skin and its accessory organs.
  3. the outermost layer, 20 to 30 cell layers thick and accounts for ¾ of the epidermal thickness. Shinglelike dead cell remnants, full of keratin. The layer provides a durable overcoat for the body. Protects deeper cells from hostile environment(air) and from water loss. Resists biological, chemical, and physical assaults. Layer is replaced by cells produced by the division of the deeper stratum basale cells. New epidermis every 25 to 45 days. (flakes off as dandruff)
  4. a clear secretion that is primarily water plus some salts (sodium chloride), vitamin C, traces of metabolic wastes (ammonia, urea, uric acid), and lactic acid(the chemical that accumulates during vigorous muscle activity) sweat is acidic pH from 4-6. Sweat reaches the surface through ducts that opens as a pore.
  5. Cells that produce melanin.

5 True/False questions

  1. Epithelial membranecomposed of epithelial tissue and an underlying layer of connective tissue. (also called covering and lining membranes, include the cutaneous membrane, the mucous membranes, and the serous membranes.


  2. Serous membranemembrane that lines a cavity without an opening to the outside of the body (except for joint cavities, which have a synovial membrane); serosa.


  3. Eccrine glandglands that have ducts through which their secretions are carried to a body surface (skin or mucosa)


  4. Keratinthe dark pigment synthesized by melanocytes responsible for skin color.


  5. Arrector pilithe membranous sac enveloping the heart.
