Why does loss of the myelin sheath around axons impair the ability to conduct electrical signals as seen in victims of multiple sclerosis?
The myelin sheath acts as an insulating layer around axons, facilitating the rapid transmission of electrical signals through a process called saltatory conduction. When the myelin sheath is damaged or lost, as in multiple sclerosis, electrical signals slow down or become disrupted, leading to impaired communication between neurons. This can result in a range of neurological symptoms, including muscle weakness, coordination issues, and sensory disturbances. Ultimately, the loss of myelin affects the efficiency and speed of nerve signal propagation.

Which condition is characterized by scattered patches of demyelination of nerve fibers of the brain?
Multiple sclerosis is a condition characterized by scattered patches of demyelination of nerve fibers in the brain and spinal cord. This demyelination disrupts the ability of nerve fibers to conduct electrical impulses, leading to various neurological symptoms.
What is the ability to transmit electrical currents called?
The ability to transmit electrical currents is called conductivity. Materials that conduct electricity well are known as conductors, while those that do not conduct electricity are known as insulators.
What is the ability to conduct electric current?

What has the ability inability to conduct an electrical current is called?
A material's ability to conduct electricity is determined by its conductivity. Materials with high conductivity can easily conduct electrical currents, while those with low conductivity have difficulty allowing the flow of electricity.
What is the nerve conduction velocity test?
It measures the ability of the nerve to conduct electrical signals
What are the two types of conductivity?
The two types of conductivity are electrical conductivity, which refers to the ability of a material to conduct electricity, and thermal conductivity, which refers to the ability of a material to conduct heat.
Ability of material to conduct heat or electritcity?
The ability of a material to conduct heat is known as thermal conductivity, while the ability to conduct electricity is known as electrical conductivity. Both properties depend on the material's atomic and molecular structure, with metals typically having high electrical conductivity and a range of materials having varying thermal conductivity.
How is ability to conduct electricity of plutonium?
Electrical resistivity of plutonium at 0C: 146.10-8 ohm.meter.
What does thermal and electrical conductivity mean?
Thermal conductivity refers to a material's ability to conduct heat, with higher conductivity indicating faster heat transfer. Electrical conductivity, on the other hand, refers to a material's ability to conduct electricity, with higher conductivity allowing better flow of electrical current. Both properties are important in various applications, such as in designing efficient cooling systems or conducting electricity in electronic devices.
What is a material's ability to conduct electricity?
A material's ability to conduct electricity is determined by its conductivity, which is a measure of how easily electrons can flow through it. Metals typically have high electrical conductivity, while insulators have low conductivity. Semiconductors fall in between and can be controlled to conduct electricity under certain conditions.
What is indium ability to conduct electricity?
Indium is a good conductor of electricity. It is often used in electronics and certain types of electrical components due to its high electrical conductivity.
What is conduct electricity means?
The ability of a material to conduct an electric current is termed as ELECTRICAL CONDUCTIVITY. Generally, ELECTRICAL CONDUCTIVITY is the ratio between ELECTRICAL FIELD STRENGTH and the CURRENT DENSITY of the conductor. The unit is Sm-1. It is also known as SPECIFIC CONDUCTANCE. ELECTRICAL CONDUCIVITY = (ELECTRICAL RESISTIVITY)-1 The unit of ELECTRICAL CONDUCIVITY is ohm- meter.
