The transmission between neurons depends on the number of neurotransmitters that are present. If there aren't enough transmitters, the impulse is not passed into the second neuron, meaning it's cut down. If there are enough, it leads to an action potential (nerve impulse) in the second neuron. The nerve system is a rather confusing, and very technical, system in the body.
What else can I help you with?
What is the difference between synaptic and nerve impulse transmission?
Synaptic transmission is chemical, while nerve impulse or axonal transmission is electrical.
What is the difference in transmission between myelinated and unmyelinated fibers?
Impulse transmission on an unmyelinated nerve fiber is much slower than the impulse transmission on a myelinated nerve fiber.
What is the difference between impulse conduction and transmission?
Impulse conduction refers to passage of impulse within the same cell. Where as transmission as the name implies, is concerned about passage of impulses either chemical or electrical from one cell to another.
What is impulse transmission?
An action potention.
What is nerve impulse transmission?
An action potention.
What is a chemical impulse?
A chemical impulse refers to the rapid transmission of signals in the nervous system, primarily involving the release of neurotransmitters at synapses between neurons. When a nerve impulse reaches the end of a neuron, it triggers the release of these chemicals, which cross the synaptic gap and bind to receptors on the adjacent neuron, facilitating communication. This process is essential for various functions, including muscle contraction, reflex actions, and the overall functioning of the brain.
Is the impulse transmission for the spinal nerve sensory or motor?
No
Which structure of a neuron increases the speed of impulse transmission?
The structure of a neuron that increases the speed of impulse transmission is the myelin sheath. This fatty insulating layer surrounds the axon and allows electrical impulses to jump between the nodes of Ranvier, which are gaps in the myelin. This process, known as saltatory conduction, significantly enhances the speed of signal transmission along the axon.
When the nerve impulse encounters a myelin-covered section of neuron?
When the nerve impulse encounters a myelin-covered section of a neuron, it jumps between the nodes of Ranvier, allowing for faster transmission speed due to saltatory conduction. Myelin acts as an insulator, preventing the impulse from dissipating and increasing the efficiency of signal transmission along the neuron.
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 increases the speed of impulse transmission?
Myelin Sheath Myelin Sheath
Increases the speed of impulse transmission?
