What else can I help you with?
Does dendrites support the axon from within?
Dendrites receive signals from other neurons and pass them to the cell body, which then transmits the signal to the axon. The axon is supported by structures called neurofilaments and microtubules that help maintain its structure and facilitate the transport of materials within the axon.
The channels that transport sodium and potassium within the axon are called?
The channels that transport sodium and potassium within the axon are called voltage-gated sodium channels and voltage-gated potassium channels. These channels play a crucial role in generating and propagating action potentials along the axon.
Can a nerve fiber survive without its cell or its axon?
No, a nerve fiber cannot survive without its cell body or axon. The cell body provides nutrients and support to the axon, while the axon is responsible for transmitting signals. Without either of these components, the nerve fiber would no longer function.
The Schwann cell forms a myelin sheath around the?
axons of neurons in the peripheral nervous system. The myelin sheath helps to insulate the axon and improve the speed of electrical signal conduction along the neuron. Schwann cells are also involved in nerve regeneration and support neuron function within the peripheral nervous system.
What is the correct route a message takes within a neuron?
Well, isn't that just a happy little question! When a message travels within a neuron, it starts at the dendrites, moves through the cell body, and then down the axon. Finally, it reaches the axon terminals where it can pass on to the next neuron. Just like painting a beautiful landscape, each step is important in creating a masterpiece of communication in our brains.

Dendrites receive signals from other neurons and pass them to the cell body, which then transmits the signal to the axon. The axon is supported by structures called neurofilaments and microtubules that help maintain its structure and facilitate the transport of materials within the axon.
As a general rule communication within a neuron progresses from?
the dendrites to the axon to the axon terminals and then to the cell body.

Action potentials are generated within the axon according to the?
All-or-none principle
Which connective tissue layer directly surrounds each axon in a nerve?
A nerve is an enclosed, cable-like bundle of axons in the peripheral nervous system. Within a nerve, each axon is surrounded by a layer of connective tissue called the endoneurium.
The Schwann cell forms a myelin sheath around the?
axons of neurons in the peripheral nervous system. The myelin sheath helps to insulate the axon and improve the speed of electrical signal conduction along the neuron. Schwann cells are also involved in nerve regeneration and support neuron function within the peripheral nervous system.

Bundles of axon within a nerve?
Bundles of axons within a nerve are called fascicles. Fascicles are surrounded by a layer of connective tissue called perineurium, which provides support and protection to the axon bundles. These fascicles work together to transmit electrical signals throughout the body.
How many axons does each neuron have?
Most neurons have one axon, which can branch into multiple axon terminals to communicate with other neurons. However, there are some exceptions where neurons have more than one axon, such as in certain neurons within the peripheral nervous system.
Does ionic current exist in chemical synapse?
not within the synaptic CLEFT (gap) itself, across which neurotransmitters diffuse, but yes, in the axon & axon terminal leading up to the synapse, and in the dendrite coming from the synapse.
Along a neuron the correct pathway for impulse conduction is?
Impulses are conducted along a neuron in one direction, from the dendrites to the cell body, then through the axon and to the axon terminals. This pathway ensures that signals are transmitted efficiently and effectively from one neuron to another or to an effector cell.
