Study Notes
Histology and Histopathology
- Histology is the study of the body's normal tissues
- Histopathology is the microscopic study of diseased tissues
Tissue Sample Collection
- Tissue samples are obtained during surgery, biopsy, or autopsy
- Surgical procedures used to retrieve tissue samples include:
- Fine needle aspiration
- Core needle biopsy
- Incisional biopsy
- Excisional biopsy
- Punch biopsy
- Shave biopsy
- Curettings
Tissue Evaluation Techniques
- The type and quantity of tissue to be assessed determine the evaluation technique
- The structural and chemical makeup of the cells to be investigated also determine the technique
- Fresh tissues are examined when an examination is required right away
- Analyzing stained slices and smears is a superior and more efficient way to examine tissues
Tissue Preparation
- Tissue samples are stained to highlight particular structures
- Coverslips are used to mount the glass slides for permanent storage
