A columnist is someone who writes for publication in a series, creating an article that usually offers commentary and opinions. Columns appear in newspapers, magazines and other publications, including blogs. They take the form of a short essay by a specific writer who offers a personal point of view.
This positive spike constitutes the action potential: the electrical signal that typically moves from the cell body dlown the axon to the axon terminals. The electrical signal moves down the axon like a wave; at each 84 Ch apter 3 Biopsycholo gy point, some of the sodium ions that enter the cell diffuse to the neJ1.'t section of the axon, raising the charge past the threshold of excitation and triggering a new influx of sodium ions.
â¢ Receives signals from other cells and sends them toward the axon. â¢ Sum up, or integrate, the incoming signals. â¢. Axon. The transmitting or conductive region of the neuron. â¢. The axon generates an action potential, an outgoing signal also called a nerve impulse, and conducts it to the next cell.â¢ Label the parts of this neuron: â¢ Neurons receive and integrate signals at one location and transmit an action potential at another location.Page 6. In most neurons, the cell body, or soma, is located centrally. â¢ Multiple similar processes, called dendrites, extend from the soma, forming a structure resembling the branches of a tree. â¢ A thin single process, called the axon, also extends from the soma.
