Chapter 4 The Tissue Level Of Organization Flashcards
Connective tissue is made up of what two things?
Cells and extracellular matrix
A cell junction that allows substances to pass through easily from cell to cell for communication and ion exchange- what type?
Gap
What type of tissue found in blood vessels that need to pass substances through very easily?
Simple squamous epithelium
Glands that release their substances (hormones) into the blood are?
Endocrine glands
What fiber in extracellular matrix of connective tissue is most abundant and provides strength and flexibility?
Collagen
What are the three types of muscle tissue ?
Smooth, skeletal, cardiac
Cells in connective tissue could be blast cells, what do they do to tissue?
Build tissue
The body requires what main thing in order for tissue to repair properly?
Blood supply
The contact pt. Between plasma membrane and adjacent tissue cells is a?
Cell junction
What are the 5 types of cell junctions?
Tight junctions, adherens, desosomes, hemisomes, gap junctions
Which type of epithelial tissue is kerantized when surface cells are dead and become hardened?
Stratified squamous epithelium
Which type of epithelial tissue allows rapid diffusion of gasses and nutrients?
Simple squamous epithelium
Which type of epithelial tissue lines the urinary bladder and karts of the urters and urethra where it permits distension of the organs?
Transitional epithelium
Glands that secrete their products into ducts that empty onto the surface of a covering and lining epithelium such as the surface of the skin
Exocrine
Connective tissue is avascular, T OR F?
False- vascular
Epithelial tissue is vascular T OR F?
False-avascular
The extrcellular matrix of connective tissue consists of two major components, what are they?
Ground substance, fibers
What are the 3 types of fibers in the extracellular matrix of connective tissue?
Collagen, elastic, reticular
Fine bundles, supporting framework, forms the stroma of many soft organs-which type of fiber?
Reticular
Thinner and elastic, located usually in the blood vessels, lungs and skin- which type of fibers?
Elastic fibers
Strong and flexible fibers, most abundant in the body
Collagen
Muscular tissue consists of cells called muscle fibers or _________, that are specialized for contraction.
Myocytes
Cardiac muscle tissue, which forms most of the heart wall is STRIATED and INVOLUNTARY T OR F?
True
Skeletal muscle tissue is attached to the bones and is striated and voluntary T OR F?
True
Smooth muscle tissue which is found in the walls of many internal structures (eg. blood vessels) is striated and voluntary T OR F?
False
What lines a body cavity that opens directly to the exterior, such as digestive, respiratory, and reproductive tracts, as well as much of the urinary tract?
Mucous membranes
The principal epithelial membranes of the body are? (3)
Mucous membrane, serous membrane, cutaneous membrane
Cartilage is one type of mature CT- because it is avascular it is relatively inactive tissue that grows slowly and regeneration proceeds how?
Slowly
Does epithelial regenerate easily and well?
Yes
