cell to cell junctions

gap junction location

intracellular pathway between adjacent cells

gap junction function

facilitate movement of small molecules ions

mesothelium location

surface layer of serous membrane, lines pleura and pericardium, abdominal cavity, pelvis

mesothelium function

lubricates movement of organs and protection

endothelium function

simple squamous

endothelium location

lines vessels of lymphatic and cardiovascular system, alveoli of lungs, kidney tubules

adherens location

inferior to tight junction, connected to actin filaments

adherens function

helps maintain cell shape

desmosome function

link adjacent cells, durable interconnections

desmosome location

linked with intermediate filaments

tight junction function

selective barrier, no extracellular space

tight junction location

digestive tract, between adjacent plasma membranes
