Question

Complate the table by using brainly brain ?

Answer 1

1. Shape:Nerve cells are usually shaped like trees. From the round, pyramidal or spindle-shaped cell body the dendrites (greek: dendrites = tree-like) branch out like the top of a tree and the single axon travels out like the trunk.     Size:They vary in size from 4 microns (.004 mm) to 100 microns (.1 mm) in diameter. Their length varies from a fraction of an inch to several feet     Nucleus:The neuron’s nucleus has the same function as all the other nuclei in all the other cells in the organism: expressing messenger RNA that is translated by ribosomes into proteins. No more. No less. The nucleus just expresses the mRNAs appropriate for a neuron, as opposed to the ones appropriate, e.g., for a muscle cell.     Structure and it's parts:The primary components of the neuron are the soma (cell body), the axon (a long slender projection that conducts electrical impulses away from the cell body), dendrites (tree-like structures that receive messages from other neurons), and synapses (specialized junctions between neurons).
