WebThe spiny protrusions on dendrites called dendritic spines form the postsynaptic component of most excitatory synapses. The dendritic spines, however, are not required for … WebOct 2, 2014 · Dendritic spines are heterogeneous in size and shape but, mostly mature ones, consist of a bulbous head and a thinner neck that connects the spine to the dendritic shaft (Wilson et al., 1983; Svoboda et al., 1996 ). This morphological configuration is particularly important for synaptic efficacy.
