A growth cone is a large actin-supported extension of a developing or regenerating neurite seeking its synaptic target. It is the growth cone that drives axon growth. Their existence was originally proposed by Spanish histologist Santiago Ramón y Cajal based upon stationary images he observed under … See more The morphology of the growth cone can be easily described by using the hand as an analogy. The fine extensions of the growth cone are pointed filopodia known as microspikes. The filopodia are like the "fingers" of the … See more Movement of the axons is controlled by an integration of its sensory and motor function (described above) which is established through second messengers such as calcium and cyclic nucleotides. The sensory function of axons is dependent on cues … See more The highly dynamic nature of growth cones allows them to respond to the surrounding environment by rapidly changing direction and branching in response to various … See more WebGrowth cone collapse is an easy and efficient test for detecting and characterizing axon guidance activities secreted or expressed by cells.
