Types of Tissue

Question 0

squamous (epithelial)

Answer 0

flat and thin; attached to each other like tiles

allows for rapid passage of substances

Question 1

epithelial tissue

Answer 1

arranged in continuous sheets, in either single or multiple layers
functions: protection, filtration, lubrication, of digestive system, secretion, absorption, and excretion
four shapes: squamous, cuboidal, columnar, and transitional

Question 2

cuboidal (epithelial)

Answer 2

thick cube or hexagon shaped

used for secretion or absorption

Question 3

columnar (epithelial)

Answer 3

tall and cylindrical

used form secretion or absorption

Question 4

transitional (epithelial)

Answer 4

readily change shape from flat to cuboidal and back

Question 5

Psuedostratified

Answer 5

looks like multiple layers but all cells rest on basement membrane

Question 6

stratified

Answer 6

two or more layers of cells

Question 7

connective tissue

Answer 7

one of the most abundant and widely distributed types of tissues in body
two basic elements: extracellular matrix and cells

Question 8

fibroblasts (connective)

Answer 8

large, flat, with branching process

secrete molecules that form the matrix

Question 9

macrophages (connective)

Answer 9

develop from monocites, a type of white blood cells
either fixed or wandering
irregular shape with short branching projections
capable of engulfing bacteria and cellular debris

Question 10

fixed macrophages

Answer 10

remain in certain tissues and organs of the body

Question 11

wandering macrophages

Answer 11

leave the blood and migrate to infected tissue

Question 12

plasma cells (connective)

Answer 12

small and either round or irregular
develop from a type of white blood cell called a B lymphocyte
they secret antibodies
mostly residing in the gastrointestinal and the respiratory tracts

Question 13

mast cells (connective)

Answer 13

abundant alongside blood vessels

produces histamine

Question 14

muscle tissue

Answer 14

produces body movement - skeletal muscles allow us to walk, run, swim, etc
stabilizes body positions - skeletal muscles allow us to keep our head up stand, sit, etc
moves substances within the body

Question 15

skeletal muscle tissue

Answer 15

attaches primarily to bone and it is responsible for locomotion, movement, and support of the skeleton
contractions aid flow of lymph and blood return to heart

Question 16

smooth muscle tissue

Answer 16

found within the walls of internal organs of the digestive system , urinary system, and blood vessels
under a microscope this tissue looks smooth (lacks striations)
involuntary
propels urine through urinary system

Question 17

cardiac muscle tissue

Answer 17

only found in the heart
tissue is striated when examined under a microscope
involuntary
contractions pump blood throughout the entire body

Question 18

nervous tissue

Answer 18

also called neurons or nerves cells

Question 19

cell body (nervous)

Answer 19

houses the nucleus; essential for survival of neuron

Question 20

dendrites (nervous)

Answer 20

usually short processes or extensions which transmit impulses toward the cell body (input)

Question 21

axons (nervous)

Answer 21

usually long process that transmits impulses away from the cell body neuroms, muscle fibers, glands, or cells (output)
