It connects to the cell body via a specialized junction known as the axon hillock.The axon is a tube-like arrangement that transports electrical impulses from the cell body to axon terminals, which then transmit the impulse to the next neuron.Neurons typically have a single major axon. all these components of Neuron Anatomy are discussed below. Dendrites, cell bodies, and axons are the three distinct components of all neurons. The form and size of a neuron structure vary based on its function and location. They are classified based on where they originate, where they project to, and which neurotransmitters they employ. Neurons of various sorts exist in both the brain and the spinal cord. Neurogenesis is a process of the formation of new neurons/ nerve cells in the brain. The myelin sheath is a fatty substance that coats, insulates, and protects brain and spinal cord nerves. The cell body, which consists of the nucleus, a large branching fiber that is the axon, and multiple smaller branching fibers that are dendrites comprise each nerve cell. The nerve cell /neuron cell is the primary unit of communication in the neurological / Nervous system. Examine the Neuron Diagram below to learn about the cell body, axon, dendrites, and overall structure of the Neuron. Almost all neurons, however, have three basic components: a cell body, an axon, and dendrites.
The size, design, and structure of neurons vary based on their function and location. The soma, or tree trunk, contains the nucleus, the neuron’s genetic material, and the proteins that are delivered across the axon and dendrites. The axon, or tree roots, is the neuron’s outflow structure when one neuron wishes to communicate with another, it sends an electrical signal called an action potential across the entire axon. Dendrites, like tree branches, branch as they grow toward their tips, and they even have leaf-like projections called spines on them. A neuron gets input from neighboring cells via a dendrite or tree branch. Neuron dendrites and axons can be compared to the branches, roots, and trunk of a mature tree, respectively. What is a Neuron?Ĭonsider a neuron structure to be a Banyan tree. Read the entire article to learn about Neuron Structure, 3 Types of Neurons and Functions, and more. A neuron is made up of three major components: dendrites, an axon, and a cell body or soma. Neurons, or nerve cells, are responsible for absorbing sensory input from the outside world, transmitting motor instructions to our muscles, and converting and relaying electrical impulses at every step in the process. Neurons receive and transfer impulses to many sections of the body in both physical and electrical ways.
Neuron: Neurons, also known as nerve cells, are the basic building blocks of the neurological system.
