What else can I help you with?
how does white matter get its name?
it contains myelin sheath which is a fatty white substance
What is the fatty tissue that covers axons and speeds up impulses as they travel from cell to cell?
The fatty tissue that covers axons and speeds up impulses is called myelin. Myelin acts as an insulating layer, which helps to increase the speed and efficiency of nerve impulse transmission along the axon.
What is axonal substance called?
Myelin is a fatty sheath around axons found in the peripheral nervous system.
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.
Where are nodes of ranvier found?
In the fatty myelin sheath there are gaps between the axons. The myelin sheath gaps are referred to as the nodes of Ranvier.
What kind of a coating do axons have?
Axons are coated in a fatty substance called myelin - a "myelin sheath". It insulates and protects the cell body of neurones. The myelin doesn't completely coat the axon: there are small gaps between the myelin, called the nodes of Ranvier.
What part of a neuron is often encased by a fatty myelin sheath?
It is located on the axon
What is the medical term meaning white protective covering over nerve cells?
The medical term is "myelin sheath." This is a fatty substance that surrounds and insulates nerve fibers, allowing for faster nerve impulse transmission. Damage to the myelin sheath can result in conditions such as multiple sclerosis.
what is the covering of a fatty material that speeds up the passage of a nerve impulse?
The covering of a fatty material that speeds up the passage of a nerve impulse is called the myelin sheath. It is made of lipids and proteins and acts as an insulating layer around the axon of a neuron, allowing for faster transmission of electrical signals.
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 are axons surrounded by?
Axons are surrounded by myelin sheath, a fatty material that insulates and protects the axon. Additionally, axons are also surrounded by Schwann cells in the peripheral nervous system and oligodendrocytes in the central nervous system, which help form the myelin sheath.
What best describes the myelin?
Myelin is a fatty substance that forms a protective sheath around nerve fibers. It acts as insulation, allowing for faster transmission of electrical signals along the nerve cells. Damage to myelin can result in neurological disorders such as multiple sclerosis.
