SC121 Unit 4 Assignment PART 2 Question #1 Name of tissue: Muscular Tissue Two characteristics used for identification: 1. Contracts & extends to make body parts move 2. Generates heat. Question #2 Name of epithelium: Stratified cuboidal epithelium Discuss the classifications of epithelial tissue based on: Cell layers The cells arranged in single or multiple layers depending on their function. 1. Simple – single layer that functions in diffusion, osmosis, filtration, secretion or absorption. 2. Pseudostratified – appears to be multiple layers because the cell nuclei lie at different levels and not all cells reach the apical surface. It is a single epithelium because all cells rest on the basement membrane. 3. Stratified – consists of two or more layers of cells that protect underlying tissues in locations where there is considerable wear and tear.
