Solution

All of the characteristics listed are present as a result of nervous tissue possessing electrical properties along the membrane. These include:

  1. The ability to have a refractory period in which the cell is insensitive to stimulation: After an action potential, there is a period of time during which the neuron cannot fire another action potential. This is known as the refractory period.

  2. The ability to generate action potentials: Action potentials are the electrical signals that neurons use to communicate with each other. They are generated when the membrane potential of a neuron reaches a certain threshold.

  3. The ability to create a relatively stable resting membrane voltage: The resting membrane potential is the voltage across the cell membrane when the neuron is at rest. It is maintained by the balance of ions inside and outside the cell.

  4. The ability to propagate multiple signals of varying strength and magnitude along the axon: The axon is the long, thin part of the neuron that carries electrical signals away from the cell body. These signals can vary in strength and magnitude.

  5. The ability to generate graded potentials: Graded potentials are changes in membrane potential that vary in size, as opposed to being all-or-nothing. They can either add to or subtract from the resting membrane potential.
