Quiz: Tissues, Chapter 4 Flashcards
What tissue type arises from all three embryonic germ layers?
Epithelial tissue
Inability to absorb digested nutrients and secrete mucus might indicate a disorder in which epithelial tissue?
Simple columnar
Glands, such as the thyroid, that secrete their products directly into the blood rather than through ducts are classified as…
Endocrine
Endothelium is…
An epithelia providing slick surface lining in all hollow cardiovascular organs
This epithelium appears to have two or three layers of cells, but the cells are in contact with the basement membrane…
Pseudostratified columnar
A many-layered epithelium with cuboidal basal cells and flat cells at its surface would be classified as…
Stratified squamous
Merocrine glands…
Are a classification of exocrine glands whose products are secreted by exocytosis (e.g. sweat and salivary)
Holocrine glands…
Are a classification of exocrine glands whose products are secreted by cell rupture and death (e.g. sebaceous)
Arteries, veins, and lymphatics keep clots from sticking as long as their ________ is intact and healthy.
Endothelium
Which cells are commonly found wedged between simple columnar epithelial cells?
Goblet cells
The fiber type that gives connective tissue great tensile strength is…
Collagen fibers
What tissue has lacunae, calcium salts, and blood vessels?
Osseous tissue
How is hyaline cartilage different from elastic or fibrocartilage?
Fibers are not normally visible
The blast cell for blood production is…
Hemocytoblast
Connective tissue matrix is composed of…
Fibers and ground substance
Only cell type found in cartilage…
Chondrocytes, which secrete cartiliginous matrix
Edema occurs when…
Areolar tissue soaks up excess fluid in an inflamed area
“Blast” cells are…
Undifferentiated, actively dividing cells
Mesenchymal cells are most commonly found in…
Embryonic connective tissue
Heart muscle cells would tend to separate without…
Intercalated discs
Membrane that lines external surfaces and helps body to communicate…
Mucous membranes
Function and Location:
Areolar Connective
Serves as soft packing around organs capable of inflation in case of injury: found in outer layers of skin and muscle, mucus membranes and organs
Function and Location:
Adipose Connectice
Insulation, storage of nutrients and energy; found in breasts, abdomen, subcutaneous tissue, around heart, kidneys and joints
Function and Location:
Reticular Connective
Delicate scaffolding that supports reticular and free blood cells; found around kidney, spleen, lymph nodes and in bone marrow
Function and Location:
Regular Dense
Retains great tensile stress, holding together bone and muscle to passively assist with movement; found in tendons and ligaments
Function and Location:
Irregular Dense
Withstands tensile strength, passively allowing for movement of the tubular organs, dermis of skin and glandular tissues it makes up
Function and Location:
Elastic Dense
Flexible tissue allows for stretch and contraction of organs without harm; found in lungs, trachea, bronchial tubes and thyroid ligaments
Function and Location:
Hyaline Cartilage
Provides smooth surfaces, allowing tissues to slide over each other easily and flexibly; found in joints, respiratory tract and embryonic skeleton
Function and Location:
Elastic Cartilage
Provides flexibility for specialized function; found in pinna of ear and epiglottis
Function and Location:
Fibrocartilage
Cartilage most like dense connective, structured to withstand significant tensile stress with some limited movement with added flexibility; found esp. in intervertebral discs of shoulder blades
