Anatomy Of A Neuron

A cell body and nerve processes. A neuron also known as a neurone old british spelling or nerve cell is an electrically excitable cell that communicates with other cells via specialized connections called synapses.

Chapter 7 Nervous System

Neurons are cells within the nervous system that transmit information to other nerve cells muscle or gland cells.

Anatomy of a neuron. A neuron consists of two major parts. Neurons contain the same cellular components as other body cells. All animals except sponges and placozoans have neurons but other multicellular organisms such as plants do not.

Myelin sheaths cover the axon and work like insulation to help keep the electrical signal inside the cell which makes it move more quickly. It is the main component of nervous tissue. Neurons basic nerve structure.

Axon nerve fibre. Soma cell body the soma or cell body is the central part of the neuron and contains. Next the signal leaves the soma and travels down the axon to the synapse.

A typical neuron has a cell body containing a nucleus and two or more long fibres. Neurons are composed of three main parts. Dendrites a cell body and an axon.

So the axon will look something like this. The central cell body is the largest part of a neuron and contains the neurons nucleus associated cytoplasm organelles and other cell structures. From there the signal travels to the main cell body known as the soma.

The neurons dendrites are effectively branching extensions of the cell body. Neurons or nerve cells are specialized cells that transmit and receive electrical signals in the body. Neuron also called nerve cell basic cell of the nervous system in vertebrates and most invertebrates from the level of the cnidarians eg corals jellyfish upward.

And at the end it ends at the axon terminal where it can connect to other dendrites or maybe to other types of tissue or muscle if the point of this neuron is to tell a muscle to do something. The neuron is the basic working unit of the brain a specialized cell designed to transmit information to other nerve cells muscle or gland cells. So at the end of the axon you have the axon terminal right there.

The basic structure of a nerve is that of a cell body soma.
