Once the materials have been collected, then the stone worker proceeds to strike the object stone, in this case the vesicular basalt, repeatedly in one place with the hard quartzite hammer stone. Quickly, the repeated pecking starts to remove material, producing a small cup like indentation, the beginning of the bowl.
From Wikipedia, the free encyclopedia. A multipolar neuron (or multipolar neurone) is a type of neuron that possesses a single (usually long) axon and many dendrites, allowing for the integration of a great deal of information from other neurons.These dendritic branches can also emerge from the nerve cell body.rom Wikipedia, the free encyclopedia. A multipolar neuron (or multipolar neurone) is a type of neuron that possesses a single (usually long) axon and many dendrites, allowing for the integration of a great deal of information from other neurons.
At the axon hillock of a typical neuron, the resting potential is around â70 millivolts (mV) and the threshold potential is around â55 mV. Synaptic inputs to a neuron cause the membrane to depolarize or hyperpolarize; that is, they cause the membrane potential to rise or fall.he course of the action potential can be divided into five parts: the rising phase, the peak phase, the falling phase, the undershoot phase, and the refractory period. During the rising phase the membrane potential depolarizes (becomes more positive). The point at which depolarization stops is called the peak phase.
