What is the strongest type of cell junction found in the body? List the four basic tissue types found in the body, briefly describing their function. Give an example of where you would find these epithelia in the body: 1) simple columnar; 2) stratified squamous; 3) transitional; 4) pseudostratified columnar. Which type of muscle tissue contains cells that can divide? What do we call the cells in nervous tissue that conduct electrical impulses? Provide THREE (3) examples of connective tissue and where they can be found in the body. How is cartilage different from all other connective tissues?
