In the nucleus of each cell, DNA is packaged into thread-like structures called chromosomes. Each chromosome consists of DNA tightly coiled around proteins called histones that support its structure. Chromosomes play a vital role in heredity, mutation, variation, and evolutionary development of species.

This describes the nucleus and it's internal structure.

A neuron is a nerve cell that processes and transmits information through electrical and chemical signals in the nervous system. Neurons consist of a cell body, dendrites (which receive signals), and an axon (which sends signals). Synaptic connections allow communication between neurons, facilitating the relay of information throughout the body.
