designated as simple if they are arranged in a single layer, or stratified if arranged in layers.
b. Connective (Figure 2-6). This tissue is widely distributed throughout the body. It binds other tissues together and supports them, forms the framework of the body, and repairs other tissues by replacing dead cells. Principal types of connective tissue are osseous (bony), cartilaginous, fibrous, elastic, and fatty. Areolar tissue, which lies under the skin and serves to fill many of the sharp corners and small spaces of the body, is a mixed type composed of fibrous, elastic, and fatty connective tissue.
c. Muscular (Figure 2-7). This tissue is of three kinds: voluntary (striated), involuntary (smooth), and cardiac.
d. Nervous (Figure 2-8). This tissue is made up of nerve cells (neurons) and supporting structure of nervous tissue (neuroglia).
