Front 1

adip-

Back 1

fat: adipose tissue--tissue that stores fat

Front 2

chondr-

Back 2

cartilage: chondroyte--cartilage cell

Front 3

-cyt

Back 3

cell: osteocyte--bone cell

Front 4

epi-

Back 4

upon, after, in addition: epithelial tissue--tissue that covers all free body surfaces.

Front 5

-glia

Back 5

glue: neuroglia--cells that support neurons; of nervous tissue.

Front 6

hist-

Back 6

web, tissue: histology--study of composition and function of tissues.

Front 7

hyal-

Back 7

resemblance to glass: hyaline cartilage--flexible tissue containing chondrocytes.

Front 8

inter-

Back 8

among, between: intercalated disc--band between adjacent cardiac muscle cells.

Front 9

macr-

Back 9

large: marophage--large phagocytic cell.

Front 10

neur-

Back 10

nerve: neuron--nerve cell.

Front 11

os-

Back 11

bone: osseous tissue--bone tissue

Front 12

phag-

Back 12

to eat: phagocyte--cell that engulfs and destroys foreign particles.

Front 13

pseud-

Back 13

false: psudostratified epithelium--tissue with flattened or scalelike cells.

Front 14

strat-

Back 14

layer: stratified epithelium--tissue with cells in layers.

Front 15

stria-

Back 15

grove: striations-- alternating light and dark cross-markings in skeletal and cardiac muscle cells.

Front 16

What are tissues?

Back 16

Organized cell structure composed in layers or groups of similar cells with a common function.

Front 17

What are the different types of intercellular junctions?

Back 17

1. Tight junction - the membranes of adjacent cells converge and fuse. Join cells in sheet-like layers, such as those in the digestive tract. All found in the brain and linings of tiny blood vessels.

2. Desmosome - "rivets or "spot welds" skin cells, enabling them to form a structural unit.

3. Gap junctions - cell membranes of certain other cells, such as those in the heart and muscle of the digested tract are connected by these tubular channels. THESE CHANNELS LINK THE CYTOPLASM OF ADJACENT CELLS AND ALLOW ION, NUTRIENTS SUCH AS SUGARS, AMINO ACIDS, AND NUCLEOTIDES AND OTHER SMALL MOLECULES TO MOVE BETWEEN THEM.

Front 18

Histology

Back 18

The study of tissues.

Front 19

List the 4 types of tissues.

Back 19

1. epithelial 2. connective, 3. muscle, 4. nervous

These tissues associate, assemble, and interact to form organs that have specialized functions.

Front 20

List the general characteristics of epithelial tissue.

Back 20

Lack blood vessels, cells readily divide, cells are tightly packed. Function: protection, secretion, absorption, excretion. Location: cover body surface, cover and line internal organs, compose glands.

Front 21

Explain how epithelial tissues are classified.

Back 21

They are classified according to cell shape and the number of cell layers. This includes squamous, cuboidal, columnar. Epithelial tissue is composed of a single layer (simple) or two or more layers (stratified).
