tissue
group o cells found together
epithelial tissue
sheet of cells that cover exterior srgace of body
connective tissue
bind cells and organs together
muscle tissue
respond to stimulation and contracting providing movement
nervous tissue
propagation of electrochemical signals in form of nerve impulses
totipotnet
capacity to divide, differentiate, develop into new organism
mesoderm
middle layer
ectoderm
outer layer
endoderm
inner layer
tissue membrane
thin layer or sheet of cells covering outside of body, internal passageways, moveable joint cavities
mucous membranes
digestive, respiratory, urinary, reproductive tracts
serous membrane
cavities close to exterior of body
cutaneous membranes
skin
synovial membranes
joint cavities, produce fluid within joint
connective tissue membranes
encapsulate organs, moveable joints
synovial membrane
connective tissue line cavity of freely moveable joint
fibroblast
inner layer of synovial membrane, release hyaluronan into joint cavity
epithelial membranes
attach to connective tissue (skin) - lamina propria(own layer) help support fragile epithelial layer - serous (mesodermally) - cutaneous ( stratified resting on top of connective tissue)
epithelium
large sheets of cells covering surfaces of the body exposed to the outer world
cell junction
adjoining cells - form specialized intercellular connection
apical
face surface of cell and basal surface
basal lamina
mixture of glycoproteins and collagen - attachment site for epithelium separates from underlying connective tissue
reticular lamina
basal attaches to - secretes underlying connective tissue forming basement membrane (holding it together)
epithelial cells
secrete, release mucous, specific chemical compounds on apical surface ( release digestive enzymes)
characterized by polarized distribution of organells
