What else can I help you with?
Is a nerve message also called a synapse?
Nerve messages are called an impulse. Synapses are the space between two axons.
Where does a nerve impulse start?
A nerve impulse typically starts at the dendrites of a neuron, where it receives signals from other neurons or sensory receptors. These signals are then transmitted down the axon of the neuron to the axon terminals, where they can communicate with other neurons or target cells.
Which of the following types of nerve fiber possesses the fastest speed of impulse propagation?
Myelinated A fibers have the fastest speed of impulse propagation among nerve fibers.
The duration of a nerve impulse is approximately?
The duration of a nerve impulse is very short, typically around 1-2 milliseconds. This rapid transmission allows for quick communication between neurons and helps to coordinate various body functions.
what is the covering of a fatty material that speeds up the passage of a nerve impulse?
The covering of a fatty material that speeds up the passage of a nerve impulse is called the myelin sheath. It is made of lipids and proteins and acts as an insulating layer around the axon of a neuron, allowing for faster transmission of electrical signals.
What is the material surrounding the axon that increases the speed of the nerve impulse?
The material surrounding the axon that increases the speed of the nerve impulse is called myelin. Myelin is a fatty substance that acts as an insulating layer, allowing for faster transmission of electrical signals along the axon.
Which two characteristics of axons increases the speed of nerve impulse?
diameter and presence of myelination.....
What is quicker a nerve impulse or a hormone?
nerve impulse
Which travels quicker through the body a nerve impulse or a hormons?
a nerve impulse
What nerve initiates the SA node to initiate an impulse?
The sinoatrial (SA) node is innervated by the vagus nerve (parasympathetic) and sympathetic nerves. However, the sympathetic nerves play a more significant role in initiating an impulse in the SA node by releasing norepinephrine, which increases heart rate.
How does a nerve impulse follow all or nothing principle?
How does a nerve impulse follow the all-or-nothing principle???
What pathway does a nerve impulse follow after initiated into a receptor?
nerve my a$$ nerve
Is an action potential necessary for a nerve impulse to occur?
Yes, an action potential is needed for a nerve impulse to occur.
Is a action potential necessary for a nerve impulse to occur?
Yes, an action potential is needed for a nerve impulse to occur.
What is a nerve impule transmitted by axons?
It is called a nerve impulse.
The neurotransmitters of a neutron enable a nerve impulse to do what?
Neurotransmitters in a neuron allow a nerve impulse to be transmitted from one neuron to another by crossing the synapse and binding to receptors on the receiving neuron. This triggers an electrical or chemical signal to continue the nerve impulse along the neural pathway.
What nerve receive the impulse?
receptors.
