Ch 4 - Cells of Nervous System Flashcards
modifies secretory proteins
golgi body
these vesicles result from invagination of the cell membrane
endosomes
protein signal that helps with endocytosis
clathrin
largest cytoskeleton part made of protofilaments… dimerized (BLANK)
microtubules, coiled
negative end of microtubules are oriented in the blank of the cell
center
making a microtubule longer process
polymerization
three main parts of a cytoskeleton
neurofilaments, microfilaments, microtubules
bones of neuron that are smaller but don’t really ever change
neurofilaments
thinnest part of skeleton only made of two strands of actin
microfilaments
microfilaments shape can change and move and are usually on the blank of the cell
outside
neurons need blank transport in order to reach the far ends of the cells
active
retrograde means transporting blank the cell body
toward
anterograde means transport blank the cell body
away from
cytoskeleton proteins only need to be transported in the blank direction
anterograde
start and stop transport that occurs because of collisions with others on the road system that have to get back on
saltatory conduction
how kyosin transports anterograde
legs attach then alternate detach to road
map 1 protein transports blank and is slower than blank
retrograde, anterograde
golgi stain simply stains the neuron blank… not the blank
dark, golgi body
most golgi bodies are in the blank but can also be spread out all over
soma
make up myelin sheath in CNS
oligodendrocytes
make up myelin sheath in PNS
schwann cells
each blank of myelin is a single schwann cell
segment
shiver is tremors due to incomplete blank
myelination
these help with saltatory conduciton
nodes of ranvier
