Muscle tissue is both extensible and elastic. The cells are contractile and are highly organized into fiber bundles. Muscle is classified according to the appearance of the contractile cells, into three types: skeletal, cardiac and smooth. The first two types have a striated appearance due to the parallel orientation of the fiber bundles.

Epithelial tissue is a highly cellular tissue that overlies body surfaces, lines cavities, and forms glands. It is avascular but innervated. Epithelial cells exist in close apposition, forming a barrier between connective tissues and free surfaces. Their surfaces face basally, apically and laterally, with each having distinctive features. Specialized epithelial tissue also exists.
