Dendrites, an axon, and a cell body are characteristics of cells found in (a) neural tissue. (b) muscle tissue. (c) connective tissue. (d) epithelial tissue.
(a) A nerve cell's long extensions enable it to conduct electrical impulses from one body part to another.
(b) The sheetlike organization of epithelial
cells enables them to protect underlying cells.
(c) The alignment of contractile proteins within
muscle cells enables them to contract, pulling
closer together the structures to which they attach.
Figure 3.1 Cells vary in shape and function.
(a) From which blood cells do microglial cells originate? (b) What are the functions of microglial cells?
