| Histology | Study of Tissues |
| Apical Surface | Exposed Surface |
| Basal Lamina | Attached surface is bound to the basement membrane or BL |
| Name 4 general types of tissues | Epithelial, Connective, Muscle, Neural |
| Primary Function of Epithelial Tissue | Protection, others include absorption and secretion |
| 2 Classifications of Epithelial Tissue | 1. Number of Cell layers (simple,stratified epithelium) 2. Shape of Cells (squamous, cuboidal,columnar) |
| Simple Squamous Epithelium | Single layer of broad, flat cells, body's most delicate epithelium, located where absorbtion or diffustion takes place, (smooth) lining of the heart, blood vessels, and ventral body cavities |
| Stratified Squamous Epithelium | located where mechanical stress is severe, top layer of skin & lining esophagus and mouth, protect against abrasion, pathogens and chemical attacks |
| Simple Cuboidal Epithelium | Located in kidney tubules. Provide limited protection, secretion and absorption |
| Stratified Cuboidal Epithelium | RAREst of all epithelium, lines some sweat gland ducts, Provides protection, secretion and absorption |
| Transitional Epithelium | Multiple layers of cells tha permit expansion and recoil after stretching. Located in bladder. |
| Simple Columnar Epithelium | Nuclei elongated, have microvilli, line stomach, intestines and tubes. Protection, secretion,absorption |
| Pseudostratified Ciliated Columnar Epithelium | Appears layered, but all attached to basal lamina, shapes of nuclei vary, have cillia at top, located in resporatory track, trachea, bronchi, parts of male reproductive tract |
| stratified Columnar Epithelium | rare, Only the superficial layer appears illongated, located in the urethra, salivary glands, pharynx, epiglottis |
