Axon terminals, also known as synaptic boutons or end bulbs, are the fine extensions at the end of an axon that transmit signals to other neurons or effector cells. These terminals contain neurotransmitters that are released into the synaptic cleft to communicate with the target cell.

Bundles of axons in the central nervous system are known as?

How is the nerve signal transmitted across the synaptic cleft?
When the nerve signal reaches the end of a neuron, it triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the neighboring neuron, initiating a new electrical signal and continuing the transmission across the synaptic cleft.
What is the structure that contains a network of axons from several anterior rami is known as?
A plexus is the structure that contains a network of axons from several anterior rami. Examples include the brachial plexus in the arm and the lumbosacral plexus in the lower back and pelvis.
What are nerve axon tracks made of?
Nerve axon tracks are made of bundles of axons, which are the long, slender projections of nerve cells that transmit electrical signals throughout the nervous system. These axon tracks are covered and insulated by a substance called myelin, which helps to speed up the transmission of nerve impulses. The axon tracks are organized in a way that allows for efficient communication between different parts of the nervous system.
What is a group of neurons with little to no myelin is known as?
A group of neurons with little to no myelin is known as unmyelinated neurons. These neurons transmit signals more slowly compared to myelinated neurons, which have a protective myelin sheath covering their axons.
Neurons are composed of a network of fine threads called?
Neurons are composed of a network of fine threads called dendrites, which receive signals from other neurons, and axons, which transmit signals to other neurons. These structures form the basic communication network within the brain and nervous system.

What is knowing as white matter that wrap themselves around some axons?
Schwann cells are known as white matter that wrap themselves around some axons.
What wraps themselves around some axons forming what is known as white matter?
Schwann Cells wrap themselves around some axons forming white matter.
How is the nerve signal transmitted across the synaptic cleft?
When the nerve signal reaches the end of a neuron, it triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the neighboring neuron, initiating a new electrical signal and continuing the transmission across the synaptic cleft.
The numerous small extensions from the soma are known as the?
dendrites
The bundles of axons in the body that travel together through the body are known as the?
Funiculi
How do you hide known file extensions?
Open any folder, click on Tools, click on the View tab and check the "Hide extensions for known file types" box.
What is the structure that contains a network of axons from several anterior rami is known as?
A plexus is the structure that contains a network of axons from several anterior rami. Examples include the brachial plexus in the arm and the lumbosacral plexus in the lower back and pelvis.
Does Jennifer Aniston shave?
She used to wear extensions, but not anymore. She said that the extensions damaged her hair, and in the past few years she's grown it out for real.
Why does windows display known file extensions?
You probably have the folder options settings chosen to to display the known files extensions. If you want to disable this option, then "Start" open up "My Computer". Now from the top nav-menu click on "Tools". A Folder Options box should appear. Click on the "View" tab. Now scroll down until you find an option that reads "Hide extensions for known file types" and put a check-mark in that box. Now "Apply" and "Ok", and now it should hide the known file extensions.
What is a series of repetitions known as?
A series of repetitions is known as a set.
