The axon of a neuron transmits electrical impulses away from the cell body to other neurons, muscles, or glands. It is responsible for carrying information over long distances within the nervous system.

What are two properties determine the conduction velocity in a mammalian neuron?

In mammalian neurons, two key properties that determine conduction velocity are the diameter of the axon and the presence or absence of myelin sheath insulation. Larger axon diameter results in faster conduction due to decreased resistance, while myelination allows for saltatory conduction, where the action potential jumps between nodes of Ranvier, increasing speed.


How is saltatory conduction different from continuous conduction?

Saltatory conduction occurs in myelinated neurons where the action potential jumps from one node of Ranvier to the next, speeding up the transmission of signals. In comparison, continuous conduction occurs in unmyelinated neurons where the action potential moves along the entire length of the axon, which is slower than saltatory conduction.


Where are nuerotransmitters stored?

Neurotransmitters are stored in tiny sacs called synaptic vesicles within the axon terminals of neurons. When an action potential travels down the neuron, these vesicles release neurotransmitters into the synapse, where they can then bind to receptors on the adjacent neuron.


What is the message that travels through the neuron?

An Impulse


How does saltatory conduction work?

Saltatory conduction is a process where nerve impulses in myelinated neurons jump between nodes of Ranvier, rather than traveling continuously along the entire length of the axon. This increases the speed of signal transmission by allowing the action potential to propagate quickly between these gaps in the myelin sheath. This efficient method of conduction conserves energy and enables rapid communication between neurons.

Does a relay neuron have a axon?

Yes, a relay neuron has an axon. Relay neurons, also known as interneurons, typically have a short axon that facilitates communication between other neurons, often within the central nervous system. Their primary function is to process and transmit information between sensory and motor neurons, contributing to reflexes and complex neural circuits.

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 a neuron have a axon?

Most neurons contain one axon. There have never been more than one found. However, some neurons contain no axon at all.


What is the function of the dentrites?

Dendrites are attaches to the axon terminals of other neurons. The nerve impulse travel from other neurons into the corresponding neuron via dendrites.


What is the function of the axon endings?

it helps to speed up the process of transmitting messages between neurons.


What factors determine the amplitude of axon potential in neurons?

The factors that determine the amplitude of axon potential in neurons include the strength of the stimulus, the size of the axon, and the presence of myelin sheath.


Neurons are classified on the basis of their structure as?

Neurons are classified into different types based on their structure as follows: multipolar neurons with many dendrites and a single axon, bipolar neurons with one dendrite and one axon, and unipolar neurons with a single process extending from the cell body that branches into dendrites and an axon.


What is the single extension of a neuron that carries signals to other neurons?

The single extension of a neuron that carries signals to other neurons is called an axon. The axon is responsible for transmitting electrical impulses away from the cell body to other neurons, muscles, or glands.

What are the two neurotransmitters that axon terminals of autonomic neurons release?

The two main neurotransmitters released by the axon terminals of autonomic neurons are acetylcholine and norepinephrine. Acetylcholine is predominantly released by parasympathetic neurons, while norepinephrine is released by sympathetic neurons.
