The axon is surrounded by the myelin sheath, which is a fatty insulating layer that speeds up the transmission of electrical signals. Outside the myelin sheath, there are Schwann cells or oligodendrocytes (depending on the type of neuron) that help form and maintain the myelin sheath.

Which connective tissue layer directly surrounds each axon in a nerve?
The endoneurium is the connective tissue layer that directly surrounds each axon in a nerve. It provides support and protection to individual nerve fibers.
In a typical neuron sheaths of fatty tissue are called?
In a typical neuron, the sheaths of fatty tissue that surround and insulate the axon are called myelin sheaths. These sheaths help to speed up the transmission of electrical impulses along the axon.
What is the fatty substance that speeds up transmission of impulses and surrounds the axon of a neuron?
The fatty substance that surrounds the axon of a neuron and speeds up the transmission of impulses is called myelin. Myelin acts as an insulating layer that helps to maintain the electrical signal within the neuron, allowing for faster and more efficient communication between cells.
What does not belong axon terminal synaptic knob bouton axon collateral?
Bouton does not belong as it refers to a swollen region along an axon where synapses are found, while axon terminal, synaptic knob, and axon collateral are all parts of the structure of a neuron.
The long process of a neuron is called the?
Axon.
Which connective tissue layer directly surrounds each axon in a nerve?
The endoneurium is the connective tissue layer that directly surrounds each axon in a nerve. It provides support and protection to individual nerve fibers.
What surrounds a single long axon that leaves many gaps?
The single long axon is surrounded by myelin sheath, which is a fatty substance produced by Schwann cells in the peripheral nervous system. The gaps along the axon are called nodes of Ranvier, where the axon is exposed and allows for faster nerve impulse transmission known as saltatory conduction.
What speeds up the passage of electrical messages by acting as a insulator of the neuronal signal?
Myelin is a fatty substance that wraps around the axon of a neuron, acting as an insulator that speeds up the transmission of electrical signals. By insulating the axon, myelin helps the signals propagate more efficiently and quickly along the neuron.
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.
In a typical neuron sheaths of fatty tissue are called?
In a typical neuron, the sheaths of fatty tissue that surround and insulate the axon are called myelin sheaths. These sheaths help to speed up the transmission of electrical impulses along the axon.
What is the fatty substance that speeds up transmission of impulses and surrounds the axon of a neuron?
The fatty substance that surrounds the axon of a neuron and speeds up the transmission of impulses is called myelin. Myelin acts as an insulating layer that helps to maintain the electrical signal within the neuron, allowing for faster and more efficient communication between cells.
Is and axon bulb and an axon hillock the same thing?
axon hillock = where cell body meets the axon axon bulb = end of the axon...lies very close to the dendrites of another neuron so impulses can pass over the synapse. AP Biology student *
Parts of a neuron include?
dendrites -Apex
The axon is made up of?
what is the axon made of
The axon is connected to the soma by the?
axon hillock
What is a axon hillock?
An axon hillock is a special cell body that connects an axon to a neuron. It is the last place where propagated membrane potentials are transmitted to the axon.
What does not belong axon terminal synaptic knob bouton axon collateral?
Bouton does not belong as it refers to a swollen region along an axon where synapses are found, while axon terminal, synaptic knob, and axon collateral are all parts of the structure of a neuron.
