The myelin sheath is a protective covering that surrounds nerve fibers and helps in efficient transmission of nerve impulses. It acts as an insulator, speeding up the transmission of signals along the nerves. Damage to the myelin sheath can result in disruptions in nerve signal transmission and lead to conditions such as multiple sclerosis.

Do neurotransmitters form the myelin sheath?
No, neurotransmitters do not form the myelin sheath. Myelin is formed by specialized types of glial cells called oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. Neurotransmitters are chemicals that are released by neurons to transmit signals across synapses.
What happens if the myelin sheath is damaged?
If the myelin sheath is damaged, nerve signals may slow down or be disrupted, leading to problems with movement, sensation, and coordination. This can result in various neurological symptoms, such as weakness, numbness, and tingling. In severe cases, it can lead to conditions like multiple sclerosis.
What are the colors of your nervous system?
Nervous tissue does not have a specific color as it is made up of cells, fibers, and blood vessels. However, nerve tissue can appear white due to the myelin sheath that surrounds certain nerve fibers.
What is the gap called that separates the myelin sheaths?
The gap between myelin sheaths is called the node of Ranvier. These nodes are important for enhancing the speed of nerve impulse transmission along the axon by allowing action potentials to "jump" between them in a process known as saltatory conduction.
What is role expectations role performances?
Role expectations refer to the societal or cultural norms that dictate how individuals are expected to behave in a specific role. Role performance refers to how individuals actually behave and carry out their responsibilities in that role. In other words, role expectations set the standard, while role performance indicates how well individuals meet those expectations.

What is myelin sheath on nerve fibers?
The endoneurium surrounds and protects the myelin sheath.
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 creates myelin sheath?
Oligodendrocytes are specialized neurolgical cells that produce myelin sheath.
What is the patchy disappearance in multiple sclerosis?

What insulates nerve fibers?
Myelin insulation insulates nerve fibers by wrapping around them and forming a protective sheath. This myelin sheath helps to increase the speed of nerve impulse conduction along the nerve fibers.
What is the sheath of a schwann cell called?
myelin sheath
What creates the myelin sheath in the PNS?
Schwann cells make the myelin sheath in the PNS. Each of the Schwann cells myelinate their own segment of the axon, they work together to make the 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
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.
