CHAPTER 4 Flashcards
a group cells that common origin
tissue
science that deals with the study of tissue
histology
physician specialized in laboratory studies of cells and tissue for diagnosis
pathologist
type of tissue that covers the body surfaces and lines hollow organs, body cavities, ducts and forms gland
epithelial tissue
type of tissue protects supports and binds organs; stores energy as fat and provides immunity
connective tissue
type of tissue that generates the physical force needed to make body structures move and generate body heat
muscular tissue
type of tissue that detects changes in body and responds by generating nerve impulses
nervous tissue
epithelial tissues developed from
ectoderm, endoderm and mesoderm
all connective tissue and most muscle tissue was derived from
mesoderm
nervous tissue developed from
ectoderm
points of contact between plasma membranes of tissue cells
cell junctions
type of cell junction that has web-like strands of transmembrane proteins
tight junctions
type of cell junction that resist separation of the cells during contractile activities.
adherens junctions
dense layer of proteins in cell junctions
plaque
type of cell junctions that has plaque and cadherins that extends into intercullular space to attach adjacent cells together
desmosomes
type of cell junction that do not link the adjacent cells but they anchor cells to the basement membrane so they don’t break apart
hemidesmosomes
type of cell junction that connects neighboring cells via tiny fluid filled tunnel
gap junction
tiny fluid filled tunnel in gap junction is called
connexons
membrane protein in connexons
connexins
thin double extracellular layer that serves as the point of attachment and support for epithelial tissue
basement membrane
