Document Summary
Page 13 of 43: in the inflammatory response, clotting proteins form a clot. What does d represent: nucleus of neuron, dendrite, cell body of neuron, axon, neuroglia cells, this is a diagram of a multipolar neuron. What does e represent: nucleus of neuron, dendrite, cell body of neuron, axon, neuroglia cells, this is a picture of a skin wound. What does e represent: dermis, subcutaneous fat, epidermis, blood vessel. Vanputte - chapter 04 #33: a tissue has the following characteristics: free surface, single layer of cells, cells are narrow and tall, microvilli, many mitochondria, goblet cells. Vanputte - chapter 04 #47: a gland produces a watery secretion that contains solutes. The secretion also contains a substantial amount of phospholipid. They are found in: neurons, tendons, muscles, intervertebral discs, bones. Vanputte - chapter 04 #75: which of the following molecules consists of numerous polysaccharides attached to a protein core, collagen.
