What else can I help you with?
The layer of lipid around an axon is called?
The layer of lipid around an axon is called myelin sheath. It acts as an insulator, allowing for faster transmission of nerve impulses along the axon.
The speed of impulse conduction along an axon may be increased by?
By myelin sheath.
The speed at which a neural impulse travels is increased when the axon is encased by an?
insulating layer called myelin sheath. This myelin sheath helps to speed up the conduction of electrical impulses along the axon by allowing the impulse to jump between nodes of Ranvier, known as saltatory conduction.
What is the name for the cleft between the internodes of the myelin sheath?
The cleft between the internodes of the myelin sheath is called the node of Ranvier. This region is important for the propagation of action potentials along the axon.
Where are the nodes of a neuron located?
Between myelin segments surrounding the axon The axon of a neuron is the single long fibre which caries impulses away from the cell body. It is surrounded by a fatty layer, the myelin sheath, produced by Schwann cells arranged along the length of the axon. The gaps between the myelin sheath cells are called nodes of Ranvier. See http://en.wikipedia.org/wiki/Axon for more information and a diagram. easy answer between the myelin segments surrounding the axon b. between myelin segments surrounding the axon
The material surrounding the axon that increases the speed of the nerve impulse is?
The material surrounding the axon that increases the speed of the nerve impulse is the myelin sheath. It is made of fatty substances and acts as an insulator, allowing for faster conduction of the electrical signal along the axon. Nodes of Ranvier are the gaps in the myelin sheath where the signal jumps between to speed up transmission.
What is the purpose of myelin sheath?
This is a process that occurs in the CNS and PNS with axons. In the CNS oligodendrocytes surround the axons and in PNS schwann cells surround the axons. the myelin sheath will increase the speed of nervous conduction along the axon.
What is the definition of myelin sheath?
A myelin sheath is a layer of myelin (a dielectric, or electric insulator) around the axon of a neuron.
What does the sheath do around the axon?
Protects the axon. The "Myelin Sheath" serves as an insulator to protect nerves.
The tightly wound cell membrane around the axon forms the myelin sheath and as acts as what?
The myelin sheath acts as an insulator, allowing for faster transmission of electrical impulses along the axon. It also helps maintain the integrity and protection of the axon.
Where is the axon not insulated with myelin?
The axon is not insulated with myelin at the nodes of Ranvier. These are small gaps along the axon where the myelin sheath is absent and allow for faster propagation of action potentials by saltatory conduction.
What are specialized coverings of the axon?
Specialized coverings of the axon include the myelin sheath, which is formed by oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. The myelin sheath acts as an insulating layer that speeds up the conduction of nerve impulses along the axon. Nodes of Ranvier are gaps in the myelin sheath where action potentials are regenerated, allowing for saltatory conduction.
