What does it mean axon?

What does it mean axon?

nerve fibre
Axon, also called nerve fibre, portion of a nerve cell (neuron) that carries nerve impulses away from the cell body. A neuron typically has one axon that connects it with other neurons or with muscle or gland cells.

What is axon in zoology?

Definition. noun, plural: axons. A long slender fibre of a neuron and is responsible for conducting nerve impulses away from the cell soma to a synapse.

What is axon process?

Each neuron in your brain has one long cable that snakes away from the main part of the cell. This cable, several times thinner than a human hair, is called an axon, and it is where electrical impulses from the neuron travel away to be received by other neurons.

What is an axon What is its function?

Specialized projections called axons allow neurons to transmit electrical and chemical signals to other cells. Neurons can also receive these signals via rootlike extensions known as dendrites.

What is a bundle of axons called?

Key Points. In the peripheral nervous system a bundle of axons is called a nerve. In the central nervous system a bundle of axons is called a tract. Each axon is surrounded by a delicate endoneurium layer. The course connective tissue layer called perineurium, binds the fibers into bundles called fascicles.

What is inside axon terminals?

At the end of an axon, there is a so-called axon terminal that is button-like and is responsible for providing synapse between neurons. The axon terminal contains specialized chemicals called neurotransmitters that are initially contained inside the synaptic vesicles.

What is an example of a axon?

An axon, or nerve fiber, is a long slender projection of a nerve cell, or neuron, that conducts electrical impulses away from the neuron’s cell body or soma. The longest axons in the human body, for example, are those of the sciatic nerve, which run from the base of the spine to the big toe of each foot.

What is another name for a bundle of nerve fibers?

Each bundle of nerve fibers is called a fasciculus and is surrounded by a layer of connective tissue called the perineurium. Within the fasciculus, each individual nerve fiber, with its myelin and neurilemma, is surrounded by connective tissue called the endoneurium.

Where are axons found?

[1] Axons are the elongated portion of the neuron located in the center of the cell between the soma and axon terminals. In size, the axon may represent over 95% of the total volume of the neuron.

What is the main function of axon terminal?

The axon terminal is important in cell to cell communication through the neurotransmitters it releases into the synaptic cleft. The neurotransmitters that exit the neuron relay signals to the next target cell.

What is called synapse?

Synapse, also called neuronal junction, the site of transmission of electric nerve impulses between two nerve cells (neurons) or between a neuron and a gland or muscle cell (effector). A synaptic connection between a neuron and a muscle cell is called a neuromuscular junction.

What is the purpose of the axon?

Regardless of how complex a neuron is, the function of an axon is usually required for the neuron to serve its purpose. Another important function of an axon is to enhance signal transmission through the use of myelin, which forms a protective sheath that surrounds it.

What is an example of an axon?

Axon, also called nerve fibre, portion of a nerve cell ( neuron) that carries nerve impulses away from the cell body. A neuron typically has one axon that connects it with other neurons or with muscle or gland cells. Some axons may be quite long, reaching, for example, from the spinal cord down to a toe.

What does an axon do in a neuron?

An axon (from Greek ἄξων áxōn, axis), or nerve fiber, is a long, slender projection of a nerve cell, or neuron, in vertebrates, that typically conducts electrical impulses known as action potentials away from the nerve cell body. The function of the axon is to transmit information to different neurons, muscles, and glands.

What is an axon in psychology?

An axon or nerve fiber, is a long, slender projection of a nerve cell, or neuron, that conducts electrical impulse s away from the neuron’s cell body or soma. Contents [psychology.wikia.com/wiki/Axons]
