What is the neural junction over which a message is transmitted?
The neural junction over which a message is transmitted is called a synapse. It is a small gap between two neurons where neurotransmitters are released to carry signals from one neuron to another. The transmission of signals across synapses is crucial for communication within the nervous system.
How is the message carried from one neuron to another if there is a space between them?
This gap is called a synaptic gap and a chemical called a neurotransmitter is used as a bridge over the gap.This message is carried via neurotransmitters. There are several types. Some speed up the transmission or slow it down or even stop it. They are like chemical bridges.
What does a Neuron turn an electrical impulses into?
A neuron turns electrical impulses into chemical signals called neurotransmitters. These neurotransmitters are released from one neuron and travel across a synapse to the next neuron, where they trigger a new electrical signal.
Where does an impulse move from on neuron to the other?
The impulse has to cross over a synapse to another neuron or an effector.
What is the difference between action potentials and synaptic potentials?
A synaptic potential exists at the INPUT of a neuron (dendrite), and an action potential occurs at the OUTPUT of a neuron (axon). (from OldGuy)(from Ilantoren:) A synaptic potential is the result of many excitatory post synaptic potentials (epsp) each one caused by the synaptic vesicles released by the pre-synaptic terminus. If there are enough of these epsp then the responses will summate and depolarize the post-synaptic membrane at the axon hillock enough to fire an action potential.
How does the signal at the synapse turn off?
The signal at the synapse is turned off primarily through the reuptake of neurotransmitters by the presynaptic neuron, where they are repackaged into vesicles or broken down by enzymes. Additionally, neurotransmitters can diffuse away from the synaptic cleft, reducing their concentration and effect. Some neurotransmitters are also inactivated by specific enzymes in the synapse, further ensuring that the signal ceases. This coordinated process allows for precise control over synaptic transmission and neural signaling.

What happens when the impulses reaches the axon terminal?
Neurotransmitters are released and go into the synaptic cleft.
What is property of synapse?
Here are some definitions of the word synapse: 1. The association of homologous chromosomes with chiasma formation that is characteristic of the first meiotic prophase and is held to be the mechanism for genetic crossing-over. 2. The definition of a synapse is the junction between two neurons or nerve cells where there is a small gap that neurotransmitters help nerve impulses to cross. 3. In popular culture, "synapse" is often used to describe a thought in a most artistic form, or even a "jerk reaction" to a certain stimuli. It would seem that the term means a place where two things (or ideas) come together or a union is formed. The synapse in the nervous system is a very tiny space when information is carried by neurotransmitters to allow the information to continue on.

How does the synapse adapt to diffusion?
The synapse adapts to diffusion by utilizing mechanisms that regulate neurotransmitter release and receptor sensitivity, ensuring effective communication between neurons. When neurotransmitters are released into the synaptic cleft, their concentration gradients drive diffusion across the synapse, allowing them to bind to receptors on the postsynaptic neuron. Over time, synaptic plasticity, such as long-term potentiation or depression, can enhance or reduce the effectiveness of this signaling based on activity levels, optimizing neural communication in response to changing conditions. Additionally, the presence of transporters and enzymes helps to clear neurotransmitters from the synaptic cleft, maintaining balance and preventing overstimulation.

What happens to left over toys at mcdonalds?
Sells them on eBay.
Why fatigue occurs in synapse?
Fatigue at synapses occurs due to the depletion of neurotransmitter stores and the reduced responsiveness of receptors during prolonged stimulation. As neurotransmitters are released repeatedly, their availability diminishes, leading to a decrease in synaptic transmission efficiency. Additionally, receptor desensitization may occur, where receptors become less responsive to neurotransmitters over time. This phenomenon helps prevent overstimulation of the postsynaptic neuron and maintains homeostasis in neural circuits.
How does the impulses get over the synapses?
Neurotransmitters. It's purely chemical.
Where does an impulse move from on neuron to the other?
The impulse has to cross over a synapse to another neuron or an effector.
What happens when Mallard eggs hatch and there are a couple left over that haven't?
they get eaten by other animals
