The part of the nerve cell that helps to speed up conduction is the myelin sheath. This insulating layer surrounds the axon and allows electrical impulses to travel more quickly by facilitating saltatory conduction, where the impulse jumps between nodes of Ranvier. This increases the efficiency and speed of signal transmission along the nerve cell.
What else can I help you with?
What part of the spine will likely cause a nerve signal to travel faster?
The cervical region of the spine is likely to allow nerve signals to travel faster. This area contains the uppermost vertebrae and has shorter nerve pathways compared to the thoracic or lumbar regions. Additionally, the myelination of nerves, which is more prominent in this region, enhances signal conduction speed. Overall, the cervical spine's structure and myelination contribute to quicker nerve signal transmission.
Why does the myelin sheath have gaps in it?
Because the sheath is produced by several Schwann cells that arrange themselves end to end along the nerve fiber, each Schwann cell forms only one part of the tiny segment of the sheath.
What structure insulates neurons?
The myelin sheath is a structure that insulates neurons. It is made up of specialized cells called oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. The myelin sheath helps to increase the speed and efficiency of nerve impulse conduction along the axon.
Is the posterior interosseous nerve a cranial nerve or a spinal nerve?
what does ninth cranial nerve control? glossopharyngeal nerve is a mixed nerve, it has sensory and motor part. the sensory is at the poserior 1/3 of the tongue. It also is part of the pharyngeal plexus. (9,10,11) The motor part of the nerve ONLY supply the stylopharyngeus muscle!
Which part of the human ear contains the auditory nerve?
The cochlea is the part of the human that contains the auditory nerve
What part of a nerve cell carries impulses toward the cell body?
There is one way conduction of impulse into the neuron, from dendrites to nerve body to axon.

What does 'as useful as' mean?
as useful as " is conduction or what part of speech it is?
What does nerve?
A motor nerve is part of the nervous system that moves muscles.
Is an axon larger than a nerve?
No, an axon is a part of a nerve cell and is smaller than a nerve, which is a bundle of axons.
