introduction to tissues and cell division

Question 1

what is a tissue

Answer 1

a tissue is an organization of similar cells that act together to perform specific functions in the body

Question 2

why are cells reproduced

Answer 2

to repair injuries, replace old, for growth

Question 3

what is interphase

Answer 3

the replication of DNA and preparation for division

Answer 9

neoplasm

Question 10

what does benign mean

Answer 10

when it doesn’t spread

Question 11

what does malignant mean

Answer 11

when it spreads

Question 12

what is cancer caused by

Answer 12

a group of diseases all characterized by uncontrolled cell division

Question 13

what causes mutations

Answer 13

carcinogens from the environment or mistakes made when the cell replicates DNA

Question 14

what is meta stasis

Answer 14

when cancer leaves the original spot and spreads to another part of the body

Question 15

what is a tight junction

Answer 15

a leak proof seal between cells

Question 16

what are desmosomes

Answer 16

attaching cells together with strength

Question 17

what are gap junction

Answer 17

allowing substances to move between cells

Question 18

what are the four types of human tissue

Answer 18

epithelial, connective, muscle, nervous

Question 19

the tissue that is made up of sheets of cells that are very tightly packed

Answer 19

epithelial tissue

Question 20

simple epithelial tissue means

Answer 20

sheet one cell thick

Question 21

stratified epithelial tissue means

Answer 21

multiple layers of cells

Question 22

what are the three subtypes of epithelial tissue

Answer 22

squamous, cuboidal, columnar

Question 23

squamous epithelial tissue is formed:

Answer 23

very wide and flat

Question 24

cuboidal epithelial tissue is formed:

Answer 24

cube shaped

Question 25

columnar epithelial tissue is formed:

Answer 25

tall and narrow like a column

Question 26

the tissue that is made of different kinds of cells and has lots of extra cellular matrix

Answer 26

Connective tissue

Question 27

what are the three subtypes of connective tissue

Answer 27

areolar, dense, specialized

Question 28

what are the three body membranes

Answer 28

cutaneous (the skin),
mucous (lines body cavities exposed to exterior),
serous (lines the body cavities not exposed to exterior)

Question 29

what are the three types of muscle tissue

Answer 29

skeletal, cardiac, smooth

Question 30

what are the two types of cells that consist of nervous tissue

Answer 30

neurons, glial cells

Question 31

what is a similarity between serous and mucus membranes

Answer 31

they both are linings for the body, serous lines cavity’s not exposed to exterior and mucus lines cavities exposed to exterior

Question 32

what is a difference between serous and mucous membranes

Answer 32

mucous is a stratified squamous or simple columnar + areolar connective tissue and serous is a simple squamous epithelial + areolar connective tissues

Question 33

what is a similarity in function between serous and mucus membranes

Answer 33

they both produce fluids for the body

Question 34

what is a difference in function between serous and mucous membranes

Answer 34

mucous is used to protect the lungs against foreign particles + chemicals entering and serous is lubricant for the pleural surfaces

Question 35

what is the tissue responsible for producing movement in organs

Answer 35

smooth muscle tissue
