interneurons

Question 6

other word for soma

Answer 6

cell body, perikaryons

Question 7

neurites

Answer 7

dendrites and axons

Question 8

nissl stain

Answer 8

labels rough er, soma, neurons and glia
its purple

Question 9

golgi stain

Answer 9

makes entire neuron visible
labels neurites
its black

Question 10

golgis theory/ reticular theory

Answer 10

that neurons are like a web- interconnected

Question 11

neuron doctrine

Answer 11

• made up of individual neurons that communicate via contact not continuity
  -energy is unidirectional goes from dendrite, soma, axon

myelin sheath

Answer 12

fatty insulation for the axons

Question 13

cytoplasm

Answer 13

stuff within the cell membrane

Question 14

cytosol

Answer 14

watery fluid inside the cell (liquidy part of the cytoplasm)

Question 15

organelles

Answer 15

membrane enclosed structures within the soma

Question 16

nucleus

Answer 16

hold dna which does not leave unless mitosis or death

Question 17

what happens in nucleus

Answer 17

gene expression
transcription
rna processing

Question 18

central dogma

Answer 18

dna (transcription)-> rna (translation)
->protein

Question 19

smooth er

Answer 19

synthesis of lipids
calcium storage
detoxifying

Question 20

golgi apparatus

Answer 20

sites for preparing/sorting proteins for delivery to different cell regions (ups)

Question 21

mitochondria

Answer 21

site of cellular respiration
provides energy for cell in form of atp

Question 22

cellular respiration

Answer 22

1. glycolysis
2. krebs cycle (citric acid cycle)
3. electron transport chain

Question 23

cytoskeleton

Answer 23

microtubules - tubulin
microfilaments -actin
neurofilaments

Question 24

phosphorylation

Answer 24

adding a phosphate to a protein

Question 25

kinase

Answer 25

adds a phosphate group to a protein

Question 26

phosphotase

Answer 26

removes the protein

Question 27

tau map

Answer 27

microtubular associated protein
organized microtubules and alignes them

Question 28

axon parts

Answer 28

axon hillock -beginning
axon proper -middle
axon terminal (bouton) -end

Question 29

difference between cytoplasm of axon terminal and axon

Answer 29

no microtubules in terminal
presence of synaptic vesicles
abundance of membrane protein
abundance of mitochondria

Question 30

no microtubules in terminal bc..

Answer 30

theres no space

Question 31

a lot of mitochondria in bouton bc..

Answer 31

it takes a lot of energy

Question 32

alternative splicing

Answer 32

removes introns exons or both to produce alternate gene products is good bc can increase fitness

Question 33

anterograde transport

Answer 33

soma to terminal-kinesin

Question 34

retrograde transport

Answer 34

terminal to soma-dynein

Question 35

vesicles (kinesin and dynein) carry..

Answer 35

proteins
pieces of organelles
lipids
neurotransmitters
ribosomes
hormones
carried back and forth which doesn’t have to do with the energy which is unidirectional
