PPT-Synaptic Transmission Functional anatomy:

As many as 10000 to 200000 minute synaptic knobs called presynaptic terminals lie on the surfaces of the dendrites and soma of the motor neuron with about 80 to 95 percent of them on the dendrites and only 5 to 20 percent on the soma. •Introduction into synaptic transmission ConventionalSynapse RibbonSynapse Action potentialsdrivephasicall ornone Transmission isgovernedbygradedpotentialsand Principles of synaptic transmissio Does it refer to 10% of brain tissue or 10% of a more abstract “functional capacity”?.
