What else can I help you with?
How do the conduction velocities of unmyelinated axons compare to myelinated axons?
Unmyelinated axons have slower conduction velocities compared to myelinated axons. Myelinated axons are able to conduct nerve impulses faster due to the insulation provided by the myelin sheath.
Do axons send or receive signals?
Axons send signals.
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 which forms a blind spot on the retina
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.
What moves across axons in the nervous system?
Electrical impulses move across axons in the nervous system.
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.
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.
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.
