Name the four classes of tissues
1. Epithelial tissue: flat sheet of tightly interconnected cells. Covers and lines all body pats
2. Connective tissue: individual cells dispersed in a flexible matrix. Holds parts together, provides mechanical support and includes bone and cartilage.
3. Muscle tissue:all muscle cells contract. Comes in three types-skeletal,cardial and smooth
4. Nervous tissue:contains neurons and Glial cells
