    1. Anatomy and Physiology Histology Unit

    2. HISTOLOGY Histology - study of tissues Tissues - the collection of specialized cells that perform a specific function.

    3. 4 TYPES OF TISSUES A. Epithelia covers exposed surfaces lines internal passageways and chambers B. Connective fills internal spaces provides structural support stores energy

    4. C. Muscle contracts to provide active movement D. Neural conducts electrical impulses and carries information

    5. Epithelial Tissue No blood vessels (avascular) functions: 1. Provide physical protection. 2. Control permeability 3. Provide sensations 4. Produce specialized secretions. Gland cells Exocrine - leave body Endocrine - released internally by gland cells ( ex. Hormones)

    6. Simple Squamous

    7. Simple Cuboidal

    8. Simple Columnar

    9. Stratified Squamous

    10. Stratified Cuboidal

    11. Stratified Columnar

    12. Transitional Epithelia

    13. Pseudostratified Columnar
