Axons and dendrites are both extensions of neurons responsible for transmitting electrical signals. However, axons transmit signals away from the cell body, while dendrites receive signals and transmit them toward the cell body. Both play crucial roles in the communication between neurons.

What are the two kinds of branches that extend from the cell body of a neuron?
The two kinds of branches that extend from the cell body of a neuron are dendrites and axons. Dendrites receive signals from other neurons and transmit them towards the cell body, while axons transmit signals away from the cell body to other neurons or target cells.
The axons of the retina culminate in what nerve?
The axons of the retina culminate in the optic nerve.
Are axons most located and protected within the CNS?
axons
Does the parasympathetic division have long preganglionic axons and a short ganglionic axon?
Yes, the parasympathetic division typically has long preganglionic axons and short ganglionic axons. The ganglia of the parasympathetic division are typically located near or within the target organ, leading to short postganglionic axons.
Are unmyelinated axons in the cerebral cortex?
Yes, unmyelinated axons are present in the cerebral cortex. While many neurons in the cerebral cortex have myelinated axons, some interneurons and shorter local circuit neurons have unmyelinated axons. These unmyelinated axons play a role in the local processing and communication within the cortex.
Can a neuron have more than two axons?
No, a neuron typically has only one axon which carries nerve impulses away from the cell body. However, certain types of neurons, such as those in invertebrates, can have multiple axon-like processes known as neurites that function in a similar way to axons.
Which elongated cell can conduct impulses?
A neuron is an elongated cell that can conduct impulses. Neurons have specialized structures called axons that transmit electrical signals over long distances within the body.
Why does action potential's move through axons in only one direction?
the axons and dentrites would get mixed up and the brain would be thinking in two ways and we would be confused to which one was which
What are the two kinds of branches that extend from the cell body of a neuron?
The two kinds of branches that extend from the cell body of a neuron are dendrites and axons. Dendrites receive signals from other neurons and transmit them towards the cell body, while axons transmit signals away from the cell body to other neurons or target cells.
What axons do nerves contain?
Nerves are like trees. The have branches call axons.
The axons of the retina culminate in what nerve?
The axons of the retina culminate in the optic nerve.
What is another name for Myelinated axons?
In preserved brains, the myelinated axons look white. Therefore, what we call "white matter" is typically made of axons.
Are axons most located and protected within the CNS?
axons
What is the bundle of axons called in the CNS?
Axons and dendrites that go to or from the same region of the body travel together in bundles, somewhat like telephone cables. A nerve is a bundle of axons and/or dendrites in the PNS. A bundle of axons and/or dendrites in the CNS is called a tract.for more info see link below
What iscomposed of lipid material and covers axons?
The myelin sheath is composed of lipid material and covers axons.
Axons and dendrites?
Axons are responsible for transmitting electrical signals away from the neuron cell body. Dendrites, on the other hand, receive incoming signals from axons of other neurons. Together, axons and dendrites play a crucial role in the communication between neurons in the nervous system.
Axons and dendrites is another word for?
Axons are the output element of a neuron, and dendrites are the input elements of a neuron.
