20
Q

indirect intercellular connections

A

uses chemical signals to communicate

21
Q

paracrine

A

from most cells to other nearby cells by diffusion through the fluid between cells

22
Q

autocrine

A

“self-message,” sends signal to cell to be sent back later

23
Q

neurotransmitter

A

from neurons to adjoining cell by fluid between the synapse connection

24
Q

endocrine

A

from glands and neurons to distant cells through the bloodstream

25
Q

genome

A

identical DNA present in every cell

26
Q

proteome

A

overall complement of proteins in cells, not the same in every cell

27
Q

lipidome

A

the different lipids present in cells, vary based on the cells job

28
Q

epithelial cells

A

set the boundary out/in

29
Q

muscle cells

A

create mechanical movement

30
Q

neurons

A

electrical communication

31
Q

connective tissue

A

provide support

32
Q

tissues

A

contains the same cell type (muscle, connective etc.)

33
Q

organs

A

combination of tissues of different types

34
Q

functional unit

A

smallest part of an organ that still completes the organs function

35
Q

redundancy

A

can be perfectly healthy while not all functional units are working

36
Q

expansion

A

can expand the organ while other units function

37
Q

organ/body systems

A

collection of organs that work together to do a similar job

38
Q

fibroblasts

A

part of connective tissue, creates fibrous proteins

39
Q

collagen

A

“rope-like” structures that allow for slight movement

40
Q

elastin

A

elastic-properties that can bounce back

41
Q

fibronectin

A

long, thin connectors that make connections

42
Q

viscosity

A

thickness of a liquid

43
Q

what is the purpose of the ECM?

A

provides structures around our cells, “bioglue” of the body

44
Q

how does the ECM influence cells?

A

helps cells survive, grow, and differentiate

45
Q

intracellular fluid

A

water within our cells, known as cytosol, most abundant

46
Q

interstitial fluid

A

fluid between our cells

47
Q

plasma

A

the water portion of the blood

48
Q

covalent bonds

A

strong bonds, sharing of electrons, and sometimes unequal sharing
