Tissues Other (E1) Flashcards
what type of tissue is mostly cellular?
epithelial tissue
what type of tissue is mostly noncellular?
connective tissue
side of a tissue cell that faces the outside or a cavity
apical
side of a tissue that connects to the basement membrane
basal
tissue type with a narrow extracellular space
epithelial tissues
type of tissue which is avascular
epithelia
what type of fibers make up the basement membrane?
reticular fibers
what forms from invagination of epithelium?
glands
secretory portion of a gland
acinus
a
duct
b
secretory portion/ acinus
what type of gland has ducts?
exocrine glands
what type of gland has no ducts?
endocrine glands
gland surrounded by blood vessels
endocrine glands
glands which secrete hormones
endocrine glands
describe how synthesis is a function of epithelia
synthesis vitamin d in the epidermis to regulate calcium which creates collagenous rigidity
what are utilized to “glue” epithelia and connective tissue at the basement membrane?
heparin and glycoproteins
layer of basal membrane facing epithelia
basal lamina
layer of basal membrane with lots of proteoglycans
basal lamina
“intercellular cement” found at basement membrane
proteoglycans
layer of basement membrane connecting to connective tissue
reticular lamina
layer of basement membrane with more fibers
reticular lamina
form a continuous seal around the cell and prevent molecules from passing between cells
tight junctions
anchoring junctions that keep cells from tearing apart
desmosomes
communicating junctions that allow ions and small molecules to pass between cells
gap juntions
channels imbedded in gap junctions
connexons
junction that reinforces the tight junctions
adherens junctions
type of junction prominent in smooth muscle
gap junction
phases of cilia movement
power/propulsive stroke and recovery stroke
function of mucus
trap bacteria and pathogens and move them from the respiratory system to the digestive system where enzymes are present to better handle the infection
components of mucus
mucin and water
process via which goblet cells secrete
exocytosis
functional tissue of an organ
parenchyma
support structures of organs (or glands)
stroma
internal invaginations of the gland that serve as barriers to limit the spread of infection
septum
glands which produce watery seretions
serous glands
example of serous gland
parotid salivary gland
