Question

Neurons are classified by the amount of metabolic activity that takes place. number of dendrites that branch out. direction in which they carry impulses. number of impulses that they carry.

Answer 1

Answer:

number of dendrites that branch out

direction in which they carry impulse

Explanation:

Neurons are the specialized cells which send and receive information. Classification of neurons is done on the basis of its structure and its function. On the basis of the number of processes that extend out from the cell body or soma, neurons are classified into unipolar, bipolar and multipolar neurons. Functionally, neurons are classified as per the direction in which the signal travels, in relation to the central nervous system. Therefore, the correct answers to this question are:

• number of dendrites that branch out- based on the structure of a neuron.  
• direction in which they carry impulses – based on the function of a neuron.

Answer 2

C.) Neurons are classified by "Direction in which they carry impulses"
