41. Unlike dendrites , an axon usually maintains the same diameter as it extends. 42. The dendrites of a single neuron can contain hundreds to thousands of spines. 43. Pyramidal dendrites typically range in diameter from half a micrometer to several micrometers. 44. CA3 projects Schaffer collaterals to apical dendrites in CA1. 45. The shorter proximal apical dendrites extend outward and below. 46. The basal dendrite however has approximately 3 fold fewer endings per primary dendrite. 47. The basal dendrite however has approximately 3 fold fewer endings per primary dendrite . 48. The closer to the body the dendrite , the higher the EPSP amplitude. 49. Conventional studies with electron microscopy or Golgi stains portrayed dendrites as stable structures. 50. ZBP1 was shown to regulate dendritogenesis ( dendrite formation ) in hippocampal neurons.
