Chapter 8 Flashcards
A tissue is
group of similar cells that perform a common
function
four principal types of tissues include
Muscle
Connective
Nervous
The most complex tissue in the body is:
nervous
tissues, the material between cells that is made up of water and a variety of proteins is referred to as:
extracellular matrix.
primary germ layers
endoderm
mesoderm
ectoderm
Which tissue lines body cavities and protects body surfaces?
epithelial
The biology of tissues is referred to as
histology
Proteins in the extracellular matrix include various types of structural protein fibers such as collagen and elastin.
True or False
True
During embryonic development, new kinds of cells can be formed from a special kind of undifferentiated cell called a stem cell.
True or false
True
the growth of new tissue (as opposed to scarring).
Regeneration
_______________________ is an unusually thick scar.
Keloid
Tissues usually repair themselves by allowing _______________________ cells to remove dead or injured cells.
Phagocytic
Epithelial and _______________________ tissues have the greatest capacity to regenerate.
Connective
Like muscle tissue, ____________________ tissue has a very limited capacity to regenerate.
Nerve
What are examples of epithelial membrane?
cutaneous membrane
serous membrane
mucous membrane
Pleurisy is a condition that affects which membrane?
serous membrane
Synovial membrane is an example of connective tissue membrane.
True or false
True
Benign tumors usually grow (slowly or quickly)
Slowly
Malignant tumors (are or are not) encapsulated.
Are not
An example of a benign tumor that arises from epithelial tissue is (papilloma or lipoma).
Papilloma
Malignant tumors that arise from connective tissues are generally called (melanoma or sarcoma).
Sarcoma
cancer specialist is an (osteologist or oncologist).
Oncolgist
Chemotherapy uses (cytotoxic or cachexic) compounds to destroy malignant cells.
Cytoxic
Directly exposed to outside environment
Skin
Thermoregulation
Cutaneous
Lubricates cavities not open to outside environment
Peritoneum
Serous
Lubricates cavities open to the outside environment
Digestive tract
Respiratory tract
Mucous
Dense fibrous connective tissue
Lines joint cavities
Synovial
Tissue cells are surrounded by or embedded in extracellular material called _____________.
Matrix
____________ tissue is often replaced, when damaged, with fibrous connective tissue instead of the original tissue.
Muscle
a glandular benign tumor..
Adenoma
is the name for “cancer genes.”
Oncogenes
Involves classifying a tumor based on the size and extent of the spread
staging
X-ray scanning
computed tomography
Substances produced by cancer cells
Tumor markers
Cytotoxic compound used to destroy malignant cell
Chemotherapy
Gamma radiation used to destroy cancer cells
Radiotherapy
Bolsters the body’s own defenses against cancer cell
Immunotherapy
Herceptin and Erbitux
monoclonal antibodies
Loss of appetite
cachexia
