The Nucleus of a neuron is an oval shaped membrane-bound structure found in the soma or body of the neuron. It contains the nucleolus and chromosomes, necessary for the coded production of proteins within the cell. The nucleolus of the nucleus produces ribosomes. The genetic information of an organism is coded within the long strands of deoxyribonucleic acid (DNA) from which the chromosomes are made. DNA is composed of two long chains that are interconnected in a helical arrangement. The sub units of a chromosome (genes) when activated induce the production of messenger ribonucleic acid (mRNA). mRNA is a duplicate of the information contained in the gene. mRNA leaves the nucleus and attaches to a ribosome, where is serves as a template for the production of a protein molecule
Parts of a neuron
Neurons vary in size, shape, and structure depending on their role and location. However, nearly all neurons have three essential parts: a cell body, an axon, and dendrites.
1. Cell body
2. Axon
3. Dendrites
Myelinated neurons are typically found in the peripheral nerves (sensory and motor neurons), while non-myelinated neurons are found in the brain and spinal cord. Dendrites or nerve endings.
