Why does destruction of myelin sheath affect motor control

Why does destruction of the myelin sheath affect motor control action potentials travel faster along myelinated fibers than along unmyelinated fibers destruction of the myelin sheath slows the time it takes for motor neurons to communicate with their effector muscles. Destruction of the myelin sheath is known as demyelination although the myelin sheath may be able to repair and regenerate itself in some cases, severe damage to it may cause the enclosed nerve to die since regeneration of nerve fibers in the brain and spinal cord is rarely possible, the nerve damage is usually permanent.

why does destruction of myelin sheath affect motor control Anatomy- multiple sclerosis/myelin sheath question in multiple sclerosis, there is progressive and intermittent damage to the myelin sheath of peripheral nerves this results in poor motor control of the affected area.

Multiple sclerosis (ms) – demyelinating nerve disease posted by dr chris what is multiple sclerosis | destruction of the myelin sheath is known as demyelination although the myelin sheath may be able to repair and regenerate itself in some cases, severe damage to it may cause the enclosed nerve to die some disorders may affect. If the myelin sheath is damaged, or destroyed, then it leaves the nervous system vulnerable to a variety of problems one of the most notable signs, particularly for suffers of multiple sclerosis, is the degradation of motor control.

The myelin sheath helps conduct nerve signals along the neuron degeneration of the myelin sheath can lead to disruption in signal conduction this disruption can lead to symptoms like arm and leg pain, visual changes, impairment in muscle function and difficulty with fine motor control.

The destruction on the myelin sheath affects motor control and other essential functions this as a result of the axons being damaged which are integral to the nerve fiber. When myelin is destroyed -- called demyelination -- nerve signals are slowed or stopped in the central nervous system -- the brain and spinal cord -- myelin cannot repair itself after it is damaged however, in the peripheral nervous system -- the nerves that travel to the arms and legs -- myelin can often regrow. Helpful, trusted answers from doctors: dr sieb on myelin sheath damage symptoms: the classic neurological diseases that involve myelin are multiple sclerosis, and neuromyelitis optica both alzheimer's and parkinson's involve nerve cell dysfnctn, and resultant neurotransmitter deficiencies some peripheral nerve disorders attack the central axon, and are termed axonal neuropathies.

The myelin sheath allows signals to be transmitted rapidly from the nervous system to the rest of the body when myelin is destroyed -- called demyelination -- nerve signals are slowed or stopped in the central nervous system -- the brain and spinal cord -- myelin cannot repair itself after it is damaged.

Myelin (definition) myelin is a fatty tissue that surrounds nerve cells, in particular the nerve cell axon this tissue is formed by other kinds of cells that support nerve cells called glial cells ( schwann cells in the peripheral nervous system and glial cells in the brain and spinal cord.

Destruction of the myelin sheath slows the time it takes for motor neurons to communicate with their effector muscles this delay in response results in varying degrees of uncoordinated muscle activity.
