| Question |
Answer |
| 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 |
