Answer 1

Answer:

Imagine your forearm, hand, and fingers as a giant model of a neuron. based on this model, fingers are to dendrites as hand is to cell body.  

Explanation:

Neurons have three basic parts: the dendrites, the axon and the cell body. If we use the forearm, hand and fingers to represent this structure, we can say that the fingers would be the dendrites, the hand is the body of the cell and the forearm the axon.

Dendrites are extensions of the neuron that guarantee the reception of stimuli, leading the nerve impulse towards the cell body. The vast majority of neurons have a large amount of dendrites.

The axon is the extension that ensures the conduction of the nerve impulse. Each neuron has only one axon, which is generally longer than the dendrites.

The cell body is the site of the neuron where the nucleus is present, most of the cell organelles, and where the extensions of that cell depart.
