![]() This branching morphology and density of the dendrites is dependent upon the type of the dendrite and its function. Dendrite branching acquires different shapes, densities, and morphology. The process of dendritic branching involves multiple steps, wherein the dendrites branch to form synapses with the axons. According to this hypothesis, sensory signals/stimulus from presynaptic neurons to a postsynaptic cell affects the course of synapse formation at the axon and dendrite junction.ĭendrites emanating multiple branching is also referred to as Dendritic arborization or dendritic branching. Image Credit: A Level Biology Dendrite Developmentĭendritic morphogenesis i.e., the dendrite growth and differentiation is affected by several factors that include:Īlthough not much is known about dendrite development and differentiation, a Synaptotropic Hypothesis has been proposed that postulates the dendritic arbor development mechanism. According to the compartmental modeling of dendrites, dendritic spines are the subcellular dendritic compartments.įigure 1: Structure of a neuron and its dendrites. Dendritic spines help to increase the surface area of the neuron and thus increase the susceptibility and detectability of the dendrites. Spines are the dendritic protrusions (not more than 2 µm) and usually have a bulbous end attached through a narrow neck.
