- Students will be able to identify the location and function of muscle tissue.
- Students will be able to identify the location and function of nervous tissue.
You have learned about the different levels of organization in living things. You may recall that In multicelular organisms, groups of similar cells that work together to perform a particular function are called tissues. Animals are multicellular organisms. In animals, groups of similar cells work together to perform a particular function. Most animals have tissues that are very specialized.
There are four basic categories of tissues; epithelial tissue, muscle tissue, connective tissue, and nervous tissue. There are many specific types of tissues within each category. For example, we will observe five types of epithelium. Tissues in each category do share some general functions.
The following video introduces tissues.
