What else can I help you with?
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.
What are the long arms of neurons called?
axons
What are the parts of neuron and its function?
The three main parts of a neuron are the soma (cell body), the axons, the long trailing output of a neuron and the dendrite or dendritic tree. Almost all neurons have axons, but not all axons have a dendritic tree.

What binds axons and blood vessels together?
The long and connected part.
What is the association of axons with nerves?
Axons are long projections of nerve cells that make up nerves. Nerves are bundles of axons transmitting information between the brain, spinal cord, and other parts of the body. Axons are responsible for carrying electrical impulses from one nerve cell to another, allowing for the communication necessary for proper functioning of the nervous system.
How long can an axon mesuare?
Axons can vary significantly in length depending on the type of neuron. In humans, some axons, like those of motor neurons that extend from the spinal cord to the toes, can measure over a meter long. In contrast, other axons can be just a fraction of a millimeter. Overall, the length of an axon is adapted to the specific functions and distances required by the neuron it serves.
What does Axons transmit?
Axons are nerve fibers which extend as long, slender projections from nerve cells. They transmit electrical and electrochemical signals across the gap at a junction(synapse) between them and the other cell.
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.
Is short preganglionic axons parasympathetic or sympathetic?
Short preganglionic axons are characteristic of the sympathetic nervous system. In the sympathetic division, these axons originate in the spinal cord and project to nearby ganglia, which are typically located close to the spinal cord. In contrast, the parasympathetic nervous system features long preganglionic axons that extend from the brainstem or sacral spinal cord to ganglia located near or within target organs.
What axons do nerves contain?
Nerves are like trees. The have branches call axons.
