tissues Flashcards
group of cells that usually have a common origin and function
tissue
medical term for tissue
histology
examines cells and tissues
pathologist
removal of a sample of living tissue fro microscopic examination
Biopsy
covers surfaces
epithelial tissue
support and protect
connective tissue
enabling movement
muscular tissue
transmit signal or nerve impulses
nervous tissues
connects cells and tissues
cell junctions
seals the space between cells
tight junction
weblike strands of transmembrane proteins
tight junctions
connects like a velcro
adherens junction
acts as a barrier to control the movement of material
tight junctions
cell junctions that contains cadherins and plaque
adherens and desmosomes
attaches both to membrane proteins and to microfilaments of the cytoskeleton
adherens junctions
it is a transmembrane glycoprotein crucial to cell to cell adhesion
cadherins
enables to withstand mechanical stress and could maintain their structure
adherens junction
a cell junction that provides structural support
adherens
a cell junction that provides strength
desmosomes
does not connect to the microfilament instead it attaches to intermediate filaments
desmosomes
what are the intermediate filaments consists of
keratin
it prevents epidermal cells from separating under tension
desmosomes
it anchors the cells to the base
hemidesmosomes
do not link any adjacent cells
hemidesmosomes
a cell junction that ensure the stability of the structure
hemidesmosomes
cell junction that has integrins transmembrane proteins
hemidesmosomes
allow communication to the cells
gap/communicating cell junctions
it covers surfaces and line cavities
surface epithelium
it forms glands
glandular epithelium
uppermost part of the epithelia
apical surface
on the side of the epithelia and contains junction except hemidesmosomes
lateral surface
