Cells are tightly packed with little intercellular substance. Protection, secretion, absorption. Cells are widely spaced with lots of intercellular matrix. Support, transport, nutrition. Muscular Elongated cells (fibers) capable of contraction. Movement of body parts. Nervous Neurons with long and short processes. Reception and transmission of impulses. Cells are tightly packed with little intercellular substance

Examine the slide under low and then high magnification. Note how closely the cells are packed.

Each tissue has a unique structure that corresponds strictly to its function. For example, the tight packing of epithelial cells provides a protective barrier, while the long processes of neurons allow for signal transmission across distances. General Write-up Tips
