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.
Is it correct that synaptic clefts prevents an impulse from being transmitted directly from one neuron to another?
Yes, that is correct. The synaptic cleft is a small gap between neurons, and it prevents direct transmission of impulses. When an impulse reaches the end of a neuron, it triggers the release of chemical messengers called neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the adjacent neuron, allowing the impulse to be transmitted indirectly.
Which neuron function is most likely affected by diisopropyl flurophosphate?
Synaptic Transmission...concerns impulse condution
Functional connection between two neurons is a?
functional connection between two neurons is the transmission of electrical signals from one neuron to another through a synapse. When an electrical impulse reaches the axon terminal of the pre-synaptic neuron, it triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the post-synaptic neuron, allowing the electrical signal to be transmitted and continue the communication between neurons.
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.
When a nerve impulse reaches the end of the axon the tiny sacs that store the neurotransmitters move to the surface and release the neurotranmistters These tiny sacs that store the neurotransmitters?
are called synaptic vesicles. They contain specific neurotransmitters that are released into the synaptic cleft when the nerve impulse reaches the end of the axon. The neurotransmitters then bind to receptors on the neighboring neuron, continuing the signal transmission.
When a presynaptic neuron is stimulated in a patients body by an electrical current neurotransmitters are released from the?
The synapse between pre synaptic and post synaptic neuron. Here the acetylcholine is released. It is destroyed by the enzyme acetylcholinesterase in milliseconds, once the impulse is passed to the post synaptic neuron
Neurotransmitters are released from what end of an axon?
synaptic vesicles
How is the message caried from one neuron to another it there is a space between them?
The synaptic gap is the space between the dendrites of one neuron and the axon of the next. The impulse is carried across this space by chemicals called neurotransmitters which conduct the electrical impulse.
How long does it take for a nerve impulse to be transmitted across the synaptic cleft resulting in a downstream muscle contraction?
The transmission of a nerve impulse across the synaptic cleft typically takes around 1 to 2 milliseconds. When the nerve impulse reaches the axon terminal, neurotransmitters are released into the synaptic cleft, binding to receptors on the muscle cell membrane. This process triggers a cascade of events that lead to muscle contraction, usually occurring within a few milliseconds after neurotransmitter binding. Overall, the entire process from nerve impulse to muscle contraction can occur in less than 10 milliseconds.
How do you tell the difference between a rat impulse paintball markers?
the Rat Impulse LTD has: a regulator, The regular Rat Impulse does not.
What is the normal sequence of events that occur during synaptic transmission at a motor end plate?
1. Nerve impulse reaches synaptic terminal. 2. Synaptic vesicles move to and merge with the presynaptic cell membrane of the motor neuron. 3. Acetylcholine is released into and diffuses across the synaptic cleft. 4. Acetylcholine binds to receptors on the postsynaptic cell membrane of the muscle fiber.
