Chapter 3 Flashcards
the microscopic study of the normal tissues of the body
histology
the microscopic study of tissues affected by disease
histopathology
the tissues are usually obtained during:
surgery, biopsy, or autopsy
the simplest, least invasive test and uses the smallest needle to simply remove cells from the area of abnormality
fine needle aspiration
removes not only cells, but also a small amount of the surrounding tissue
core needle biopsy
takes out even more surrounding tissue. it takes out some of the abnormality, but not all. the doctor will slice into the lesion and remove only a portion of it
incisional biopsy
generally removes the entire area in question
excisional biopsy
considered the primary technique for obtaining diagnostic full-thickness skin specimens. it requires basic general surgical and suture-trying skills and is easy to learn
punch biopsy
where small fragments of tissue are “shaved” from a surface (usually skin)
shave biopsy
where tissue is scooped or spooned to remove tissue or growths from body cavity such as endometrium or cervical canal
curettings
proteins and cells are digested and broken down by their own enzymes, independent of a bacterial action
autolysis
