Document Summary
Golgi stain such as cell body vs axon and dendrites. Branching from axon are generally @ right angles. -inside surface of membrane facing synapse has particularly dense covering of proteins. Wallerian degeneration: interruptedmovement down axon = . Kinesin moves material from soma to terminal ( anterograde transport) Unusual changes in spines have correlation to individuals w cognitive impairments. Dendritic cytoplasm like axon cyto but contain local protein synth in some neurons. Stellate (star like) ; presence/absence of spine: . Extent of change correlated to degree of disability. Do not extend beyond vicinity of cell body. Regulating chemical content in the extracellular space (regulates nt reuptake; Influences whether a neurite can grow or retract concentration of k ions in extracellular fluid) Only in cns; myelin to several axons development. - ribosomes absent in axon-- proteins in axon terminal are provided by soma via axoplasmic transport.
