Flashcards in C-words Deck (22):
1

cAMP

cyclic adenosine monophosphate, signaling molecule

2

capacitance vessels

alternate name for veins because of their large compliance

3

carotid sinus

widening of the internal carotid artery at its origin, containing many baroceptors

4

catecholamines

biogenic amines based on the catechol structure (aromatic six carbon ring with two OH-groups) dopamine, norepinephrine, epinephrine

5

cellulose

polysaccharide built up of glucose molecules forming straight chains

6

choroid plexus

plexus of cells that produces the cerebrospinal fluid in the ventricles of the brain

7

cis and trans position

on the same or opposite side (e.g. the two possibilities of the continuation of the lipid chain at the two ends of a double bond in an unsaturated fatty acid)

8

CoA, coenzyme-A

coenzyme built around the adenine nucleotide

9

collagen

protein and the main component of the collagen fibers

10

collateral processes

branches of an axon terminating in locations other than the major target location

11

colloid osmotic pressure

proteins, mostly albumins, in a blood vessel's plasma that tends to pull water in to the circulatory system

12

colocalization

when two transmitters, or a transmitter and a neuromodulator, are present in the same synaptic vesicle at the same time

13

compartmentalization

the formation of cellular compartments

14

compensatory pause

longer pause between two heart beats following an extra systole

15

competitive inhibition

the enzyme may bind to the inhibitor, the substrate, or neither, but it cannot bind both at the same time

16

complement system

protein molecules responsible for the elimination of the antigen-antibody complex

17

concentration gradient

change in the concentration of a substance depending on distance

18

conductance

reciprocal value of the resistance

19

conformational change

reversible change in the structure of a protein molecule

20

contractility

ability for shortening

21

convection

movement of substances caused by pressure differences

22

covalent bond

the strongest bond between two atoms that involves the sharing of electron pairs
