Bodies come from bequests, not condemned criminals or unclaimed bodies

Question 2

what is informed consent?

Answer 2

people while alive made the free choice to donate their bodies

what are prosections?

Answer 3

dipped in silicon so that nothing bad happens when we touch them - lasts for a long time

Question 3

what is the human tissue act?

Answer 3

• voluntary donation of bodies
• requires dual signed consent by the donor and an immediate family member
• most bodies are held for 18 months, however can be kept for longer period for teaching and research

• nervous tissue

Question 5

what does an atom combine to form?

Answer 5

molecules

Question 6

what do molecules interact to form?

Answer 6

cells

Question 7

Cells that secrete and regulate are called -

Answer 7

extracellular material (stuff outside of cell)

Question 8

the cell and extracellular material form to combine -

Answer 8

tissues

Question 9

why does tissue have different physical properties and different structures of what they look like?

Answer 9

because the cell and extracellular material are different then we can classify things based on what is similar and different

Question 10

what is epithelial tissue

Answer 10

made up of sheets of cells that are tightly held together - not a lot of space between them

Question 11

why do they provide excellent physical protection?

Answer 11

because there is not a lot of space between them

Question 12

how does epithelial tissue control permeability?

Answer 12

epithelium and skin help with permeability

Question 13

what tissue secretes things?

Answer 13

epithelial tissue

Question 14

what are epithelial glands?

Answer 14

is folding that tissue to fit more cells into a small area so there can be concentrated secretions

• exocrine glands
• endocrine glands

Question 16

what does apical mean in terms of epithelial tissue?

Answer 16

the outer surface (microvilli)

Question 17

what does basolateral mean in terms of epithelial tissue?

Answer 17

the bottom surface

Question 18

what are the four functions of epithelial tissue?

Answer 18

• provides physical protection
• controls permeability
• provide sensation
• produce specialized secetions

Question 25

what are the 6 functions of connective tissue?

Answer 25

- a structural framework for the body - transport fluid and dissolved material protect delicate organs - support, surround, and interconnect other types of tissue - store energy in the form of triglycerides - defend the body from invading microorganisms

Question 26

what are the two important fibers?

Answer 26

collagen fiber: thicker and stronger elastic fiber: stretchy

Question 27

fluid connective tissue contains?

Answer 27

immune cells to protect us

Question 28

what is connective tissue proper?

Answer 28

- sheets and bands of tissue that are very strong and stretchy depending on the need - fill in space in the body - wrap around the body to protect organs - in the form of adipose storing energy as well
