Definition: Portion of a neuron that conveys the neural impulse away from the cell body to the terminal button.
What is an axon?
An axon is a long, thin fiber that conducts electrical signals away from the cell body of a neuron. The axon is typically covered in a myelin sheath, which is a fatty layer that helps to insulate the axon and speed up the transmission of electrical signals.
What is the axon and its function?
The axon is responsible for carrying electrical signals away from the cell body of a neuron to other neurons or to muscles. The axon is the longest part of a neuron, and its length can vary depending on the type of neuron. For example, the axons of some neurons in the brain can be up to a meter long.
What is the axon on a nerve?
The axons of many neurons are bundled together to form nerves. Nerves are responsible for carrying electrical signals from the brain and spinal cord to other parts of the body. The auditory nerve, for example, is responsible for carrying electrical signals from the inner ear to the brain.
What are axons and dendrites?
Axons and dendrites are both parts of a neuron. An axon is a long, thin fiber that conducts electrical signals away from the cell body of a neuron. A dendrite is a short, branched fiber that receives electrical signals from other neurons.
Axons can be myelinated or unmyelinated. Myelinated axons are covered in a fatty layer that helps to insulate the axon and speed up the transmission of electrical signals. Unmyelinated axons do not have a myelin sheath.
The number of axons in a neuron can vary depending on the type of neuron. For example, some neurons in the brain may have only a few axons, while other neurons may have thousands of axons.
The axon of a neuron can be damaged by injury or disease. If an axon is damaged, it may not be able to conduct electrical signals properly. This can lead to a variety of problems, depending on the location of the damaged axon.
What are dendrites?
Dendrites can be branched or unbranched. Branched dendrites have multiple branches that receive electrical signals from other neurons. Unbranched dendrites do not have any branches.
The number of dendrites in a neuron can vary depending on the type of neuron. For example, some neurons in the brain may have only a few dendrites, while other neurons may have thousands of dendrites.
The dendrites of a neuron can be damaged by injury or disease. If a dendrite is damaged, it may not be able to receive electrical signals properly. This can lead to a variety of problems, depending on the location of the damaged dendrite.
