module 2 Flashcards
at the beginning of an axon what ion gate is present more then anywhere in the neuron
sodium gated ion channel
does the soma and dendrite have the same material as the dendrite initial part ? yes or no
yes , hence unlike the axon beggining the begginning of a dendrite has similar features as the soma body with rer, golgi etc. overall this is called polarisation
what forms the cytoskeleton ?
fibers and asssociated proteins
what is the function of the cytoskeleton in a neuron ?
it provides internal framework, shape, distribution/localisation/anchoring of organelles and membrane protein scaffolding
what is the meaning of dynamic structure in a neuron cytoskeleton context ?
its a dynamic structure eg microtubules and actin change during growth and development and plasticity.
what is the neuronal cytoskeleton made of ?
microtubule, neurofilament and microfilaments
give an example of a microtubule
tubulin filaments
give an example of neurofilaments
intermediate filament
give an example of microfilament
f-actin filamentous and g actin - monomeric.
