What else can I help you with?
Which structure if the neuron transmits an impulse through the myelin sheath?
Neural impulses (action potentials) are transmitted through axons which are covered in a myelin sheath for insulation.
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
What are components of a nerve fiber?
A nerve fiber consists of the axon, which transmits nerve impulses, along with protective covering called myelin sheath, Schwann cells that produce myelin, and the endoneurium which surrounds individual nerve fibers.
Neural impulses speed increases when the axon is encased by what?
Myelin Sheath
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.
Impulses are conducted rapidly if is present?
Myelin sheath. It is a fatty layer that surrounds the axon of a neuron and helps to speed up the transmission of electrical impulses along the neuron.
State the structure of neurons which reduces leakage of impulses?
Neurons are covered by a myelin sheath, which consists of layers of fatty tissue that insulates the axon and reduces leakage of impulses. The myelin sheath is formed by specialized cells called oligodendrocytes in the central nervous system, and Schwann cells in the peripheral nervous system. This insulation allows for faster and more efficient transmission of electrical impulses along the axon.
What is the fatty tissue that covers axons and speeds up impulses as they travel from cell to cell?
The fatty tissue that covers axons and speeds up impulses is called myelin. Myelin acts as an insulating layer, which helps to increase the speed and efficiency of nerve impulse transmission along the axon.
How is the structure of the myelin sheath related to its function?
Myelin sheath is the "cover" if you like of nerves. It's structure is important in helping pass the nerve impulses along it's axon, from the body, to the terminal buttons. Long story short, a degeneration of the Myelin sheath leads to interrupted, or non existent impulses, and causes a very well known disease, called MS (multiple sclerosis)
How does the myelin sheath and synapse affect nerve impulses speed up or slow down?
The myelin sheath acts as an insulating layer that helps speed up nerve impulses by allowing them to "jump" between gaps in the sheath called nodes of Ranvier. This process, known as saltatory conduction, accelerates the transmission of nerve impulses along the axon. At the synapse, neurotransmitters are released to transmit signals between neurons. The efficiency of this process can also affect the speed of nerve impulse transmission.
The speed at which a neural impulse travels is increased when the axon is encased by an?
insulating layer called myelin sheath. This myelin sheath helps to speed up the conduction of electrical impulses along the axon by allowing the impulse to jump between nodes of Ranvier, known as saltatory conduction.
The greater the amount of coating the axon the faster the nerve impulse will be transmitted to the synapse.?
myelin
