Is a oligodendrocye a neuroglial cell is a phagocyte?
Oligodendrocytes - specialized neuroglial cells that assist in production of the myelin sheath.
What does myelin sheath wrap around?
The myelin sheath wraps around the around the axon of a neuron. The gaps of the myelin sheath are not insulated and are therefore capable of generating electrical activity.
Neurons can conduct messages faster if they have?
A myelin sheath.
What would happen if the neuron did not have a myelin sheath?
if neurons didn't have myelin sheath then the transmission of nerve impulses is slowed or stopped
State the structure of neurons which reduces leakage of impulses?
Myelin sheath, which is only found on long axons (white matter), not on short cortical neurons (grey matter).
What is the fatty substance that speeds up transmission of impulses and surrounds the axon of a neuron?
The fatty tissue surrounding the axon of a neuron is called myelin.
Imagine two neurons one is wrapped with a myelin sheath and has a large diameter the second neuron has no myelin sheath and a narrow diameter which of these neurons conducts a nerve impulse more rap?
Neurons send their impulses up and down the spinal cord. The myelin sheath is the coating around the spinal cord that protects it, and works to better conduct the signals along the cord. A neuron that has no myelin sheath will have a harder time conducting signals than one that is covered by the sheath.
The layer of lipid around an axon is called?
Myelin sheath
What is the medical term meaning hardening and degeneration of the myelin sheath?
Muscular sclerosis is hardening and degeneration of the myelin sheath. Muscular sclerosis Multiple sclerosis is a disorder marked by destruction of the myelin sheath on neurons in the CNS and replacement with hard scar tissue.
What cell main function is to provide insulation and structure for neurons?
myelin sheath
What is the sheath of a schwann cell called?
myelin sheath
What structure insulates neurons?
Myelin Sheath is the structure that insulates most part of neuron
