The function of the myelin sheath is to insulate the axon of the neuron. When there are gaps in the sheath, known as nodes of Ranvier, the nerve impulse can jump from gap to gap, thus increasing greatly the speed of conduction of the nerve impulse. This is known as saltatory conduction.
What else can I help you with?
What is important in building myelin sheaths and cell membranes?
Building myelin sheaths and cell membranes requires an adequate supply of essential nutrients, particularly fatty acids like omega-3 and omega-6. Phospholipids are also crucial for membrane structure and function. Additionally, the presence of certain proteins, such as myelin basic protein, is necessary for the formation and maintenance of myelin sheaths.
Where are myelin sheaths located?
Myelin sheaths are located around the nerve cells. In central as well as peripheral nervous system.
Is it becaue they are large with thick myelin sheaths?
Your question is not complete. There is not enough information. What are you referring to as "they". Some nerve fibers have thick myelin sheaths and some don't.
What cell main function is to provide insulation and structure for neurons?
The main function of glial cells, specifically oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system, is to provide insulation to neurons through the formation of myelin sheaths. These myelin sheaths wrap around the axons of neurons, which helps to increase the speed and efficiency of electrical signal conduction along the neuron.
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.
The speed of impulse conduction along an axon may be increased by?
By myelin sheath.
Which neuroglial cell is responsible for the production of myelin sheaths around axons in the central nervous system?
Oligodendrocyte; processes of the oligodendrocytes form the myelin sheaths around the CNS nerve fibers
What features of nerves improve impulse conduction velocity?
myelin sheaths
Does oligodendrocytes serve the same purpose in the central nervous and periphial nervous system?
No, they form myelin sheaths on axons in the CNS while schwann cells form myelin sheaths in the PNS. Hope this answers your question.
Does myelin sheaths slow down nerve impluses?
No, myelin sheaths actually speed up nerve impulses by increasing the speed of signal transmission along the nerve fibers. This is due to the insulation effect of myelin, which helps to prevent signal loss or leakage.
What are progressive destruction of myelin sheaths in the central nervous system is called?
MS
Does a nervous breakdown affect the myelin sheaths?
No. It does not. It can not. It neither affect the neurons also.
