Larger axons are typically wrapped with a fatty substance called myelin, which is produced by Schwann cells in the peripheral nervous system and oligodendrocytes in the central nervous system. Myelin serves as an insulating layer that helps to increase the speed and efficiency of nerve impulse conduction along the axon.
What else can I help you with?
What is the name of covering of axon?
Because this is tissue from the brain (CNS), it is an oligodendrocyte which wraps around axons of neurons in the CNS to form a fatty myelin sheath. If it were PNS axons in say spinal or cranial nerves, the answer would be be Schwann cells.
Neurilemma is wrapped around most exons in the nervous system excpect for the?
Neurilemma, or Schwann cell membrane, wraps around most axons in the peripheral nervous system, providing insulation and support. This covering is absent in the central nervous system, where axons are myelinated by oligodendrocytes instead.
What contains myelinated axons?
Myelinated axons are found in the central nervous system (CNS) within areas such as the brain and spinal cord, as well as in the peripheral nervous system (PNS) within nerves outside the CNS. Myelin, a fatty substance produced by glial cells like oligodendrocytes in the CNS and Schwann cells in the PNS, wraps around these axons to insulate and speed up the transmission of nerve impulses.
The most rapid action potentials are conducted on?
The most rapid action potentials are conducted on myelinated axons, specifically those with a larger diameter. Myelination and a larger diameter help to increase the speed of conduction by decreasing capacitance and resistance.
Which type of axon will velocity of action potential conduction be the fastest?
Myelinated axons with a larger diameter will conduct action potentials the fastest due to saltatory conduction, where the action potential jumps from one node of Ranvier to the next, skipping the myelin-covered regions. Smaller-diameter and unmyelinated axons will conduct action potentials more slowly.
What is fat and white and wraps around the fastest axons?
The Myelin sheath is fat and white and wraps around the fastest axons.
What wraps themselves around some axons forming what is known as white matter?
Schwann Cells wrap themselves around some axons forming white matter.
What is the name of covering of axon?
Because this is tissue from the brain (CNS), it is an oligodendrocyte which wraps around axons of neurons in the CNS to form a fatty myelin sheath. If it were PNS axons in say spinal or cranial nerves, the answer would be be Schwann cells.

Neurilemma, or Schwann cell membrane, wraps around most axons in the peripheral nervous system, providing insulation and support. This covering is absent in the central nervous system, where axons are myelinated by oligodendrocytes instead.
Why does increasing the axon diameter also increase the speed of impulse conduction?
Larger diameter axons conduct impulses more rapidly than axons with a smaller diameter. Larger axons tend to be myelinated and conduct impulses rapidly. Myelin is a substance rich in lipid that forms an electrical insulation layer around the axon. This insulating myelin sheath allows impulses to be transmitted more rapidly then small diameter axons that are nonmyelinated.
What contains myelinated axons?
Myelinated axons are found in the central nervous system (CNS) within areas such as the brain and spinal cord, as well as in the peripheral nervous system (PNS) within nerves outside the CNS. Myelin, a fatty substance produced by glial cells like oligodendrocytes in the CNS and Schwann cells in the PNS, wraps around these axons to insulate and speed up the transmission of nerve impulses.
What does myelin sheath wrap around?
The myelin sheath wraps around the axons of neurons in the nervous system. This fatty layer helps to insulate and protect the axon, allowing for faster transmission of electrical signals along the neuron.
What cells in the peripheral nervous system that form a covering around axons?
Schwann cells wrap around the AXONS of peripheral neurons.
What cells are responsible for the myelination of neurons in the cns?
In the central nervous system (CNS), oligodendrocytes are responsible for myelinating neurons. These specialized cells form the myelin sheath around axons, which helps in the transmission of nerve signals.
What is knowing as white matter that wrap themselves around some axons?
Schwann cells are known as white matter that wrap themselves around some axons.
The most rapid action potentials are conducted on?
The most rapid action potentials are conducted on myelinated axons, specifically those with a larger diameter. Myelination and a larger diameter help to increase the speed of conduction by decreasing capacitance and resistance.
Neurons can conduct messages faster if they have?
myelinated axons. Myelin is a fatty substance that wraps around the axon, acting as an insulator to increase the speed of electrical impulses traveling along the neuron. This allows for faster and more efficient communication within the nervous system.
