Do oligodendrocytes have cytoplasmic extensions?
Yes, oligodendrocytes have cytoplasmic extensions. These extensions, known as processes, allow oligodendrocytes to wrap around axons in the central nervous system, forming the myelin sheath that insulates and facilitates the efficient transmission of electrical signals. Each oligodendrocyte can extend its processes to multiple axons, contributing to the myelination of several neurons simultaneously. This structural feature is crucial for the proper functioning of neural circuits.
Bundles of axons in the central nervous system are known as?
Tracts...
How is the nerve signal transmitted across the synaptic cleft?
Nerve impulses are collected from neighbouring neurons through branched extensions or 'dendrites'. They enter the neuronal cell body for processing and are then propagated along... travel at definite rates along axons which split or 'bifurcate' into thousands of branches which terminate as 'axon terminals' also known as 'synaptic knobs' and 'synaptic buttons'. Axon terminals connect with dendrites of neigbouring neurons at specialized points of contact known as 'neural junctions', 'synaptic junctions' or 'synapses'.

What are the stringy things on a nerve cell?
The stringy things on a nerve cell are known as dendrites and axons. Dendrites are the branching extensions that receive signals from other neurons, while the axon is a long, thin projection that transmits electrical impulses away from the cell body to other neurons or muscles. Together, these structures facilitate communication within the nervous system.
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.
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 wraps themselves around some axons forming what is known as white matter?
Schwann Cells wrap themselves around some axons forming white matter.
The bundles of axons in the body that travel together through the body are known as the?
Funiculi
The numerous small extensions from the soma are known as the?
dendrites
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.
Why are myelinated axons faster than unmyelinated axons?
Myelinated axons are faster than unmyelinated axons because the myelin sheath acts as an insulator, allowing for faster transmission of electrical signals along the axon. This insulation helps to prevent signal loss and allows the electrical impulse to "jump" from one node of Ranvier to the next, a process known as saltatory conduction, which speeds up the transmission of the signal.
