Question

are used to send electrical signals only short distances in the nervous system. answers: a - e a graded potentials b signal potential c integration potentials d summation potentials e action potentials

Explanation:

Graded potentials are local changes in membrane potential that vary in magnitude. They are used for short - distance communication in the nervous system as they decay with distance. Action potentials, on the other hand, are used for long - distance communication. Options B (Signal potential is not a standard term in this context), C (Integration is a function of neurons involving summation of potentials, not a type of potential), and D (Summation is a process, not a type of potential) are incorrect.

Answer:

A. Graded potentials
