The myelin sheath around nerve tracts insulate and protect the nerve from too much stimulation and it also makes the electrical current, that is used to feel and move, move faster through the body. People who lack the myelin sheath have serious and life threatening problems because their bodies do not move when it is supposed to, one common disorder of demyelination is multiple sclerosis.

What do amylase trypsin and lipase break down?
Amylase has a shap which allows it to wrap around and cut up starch. Lipase breaks down the fat to fatty acids and glycerol Amylase has a shap which allows it to wrap around and cut up starch. Lipase breaks down the fat to fatty acids and glycerol
What is the path of an electrical impulse as it moves through a neuron?
The electrical impulse travels into the dendrites, the "input" of the neuron, and into the soma or "body" where the signal gets processed. From there, the processed signal travels down the axon or "output" and into the dendrites of another neuron.
When you touch something hot a neuron in you finger senses the temperature which happens first?
an action forms
What is a message that travels through the neuron?
An Impulse
What is the difference between a hydrocarbon and a fatty acid?
The difference between a hydrocarbon and a fatty acid is that a fatty acid is a hydrocarbon chain with a carboxylic acid head.
Does a neuron have a coating?
Sometimes, depending on the type and function of the neuron, and when it does, it will be on the AXON of the neuron, not the whole neuron. The AXONS of grey matter in the brain do NOT have a coating, but white matter in the brain DOES, as do longer axons in the peripheral nervous system. The Myelin Sheath which coats white matter in the brain is made up of glial cells called oligodendrocytes, and the myelin sheath around peripheral nerve cells are called Schwann cells.
Fatty covering material of neuron fibers?
Yelin
Neurons which are wrapped in a fatty membrane are?
Neurons wrapped in a fatty membrane are called myelinated neurons. The fatty substance that wraps around the neuron is called myelin, and it helps to insulate and speed up the transmission of electrical impulses along the neuron's axon. Myelinated neurons are found in the central and peripheral nervous system.
What part of a neuron is often encased by a fatty myelin sheath?
It is located on the axon
This structure of the neuron plays a role similar to the rubber coating?
Myelin sheath, comprised of glial cells wrapped around an axon one after another (oligodendrocytes in the CNS, schwann cells in the PNS).
Why is there fat coating around the dendrites and axons?
The myelin sheath, which is the fatty coating surrounding dendrites and axons, helps to insulate and protect these structures. It speeds up the transmission of nerve impulses down the axon during neural communication, allowing for efficient signaling in the nervous system.
What is the coating that creates white matter?
The white matter in the brain is created by myelin, which is a fatty substance that forms a protective coating around nerve fibers. Myelin helps to insulate and speed up the transmission of electrical signals between neurons.
In a typical neuron sheaths of fatty tissue are called?
In a typical neuron, sheaths of fatty tissue are called the Myelin sheath. The myelin sheath surrounds parts of the axon of a nerve cell which speeds up neurotransmitters.
What is the fatty substance that speeds up transmission of impulses and surrounds the axon of a neuron?
The fatty substance that surrounds the axon of a neuron and speeds up the transmission of impulses is called myelin. Myelin acts as an insulating layer that helps to maintain the electrical signal within the neuron, allowing for faster and more efficient communication between cells.
What is the insulating material found around a neuron?
myelin, although it is really only around the AXON of the neuron, not the whole neuron.
What cell is insulated by a fatty layer?
Nerve cells, or neurons, are insulated by a fatty layer called myelin. This myelin sheath helps to insulate and protect the axon, which allows for faster transmission of electrical impulses along the neuron.
What does the cerebral cortex compose of?
The cerebral cortex is composed of neuron cell bodies which lack the fatty white myelin sheaths around the axons and so is sometimes referred to as gray matter.
