What happens to the neurotransmitter once it is released?
Neurotransmitter diffuses across the synaptic cleft to bind to the receptor on the muscle or next nerve.It is then broken down and absorbed back into the nerve.NovaNET answer: quickly destroyed..........Good Luck :)
Presynaptic neurons release neurotransmitters by?
An action potential travels down the neuron and reaches the presynaptic knob. This causes the Calcium ion channels to open and allow an influx of calcium into the knob. The increased concentration of calcium causes the secretory vesicles within the knob to bind to the outer membrane and release their neurotransmitter (e.g. ACh) into the synaptic cleft.
What happens with the many synaptic inputs on a cell body?
Ca ions bind to their binding sites that in turn allows Na ions to flood into the cell body and cause depolarization. this will continue down the cells axon until it bombardes the next cell with synaptic input
What is a sub-threshold change in membrane potential within the cell body that decays as it travels away from its point of origin?
A sub-threshold change in membrane potential in the cell body, such as an excitatory post-synaptic potential (EPSP), does not reach the threshold for action potential initiation. As it travels along the dendrites and cell body, it decays and dissipates, failing to trigger an action potential. This phenomenon is crucial in the integration of signals by neurons.
How are synapses adapted for diffusion?
Synapses are adapted for diffusion through the presence of neurotransmitter receptors on the postsynaptic membrane, which allow for the binding of neurotransmitters released from the presynaptic neuron. The synaptic cleft, a small gap between the pre- and postsynaptic neurons, ensures that neurotransmitters can diffuse across and bind to receptors efficiently. Additionally, the presence of enzymes in the synaptic cleft helps to degrade neurotransmitters after they have exerted their effects, allowing for precise control of neurotransmission.

In which direction does the message travel in the neuron?
it travels through the dendrite to the synaptic terminal to the axon
How a neuron sends internal messages?
Neurons send internal messages through the use of action potentials, which are generated through the summation of inputs from the dendrites on the other part of the neuron. These inputs are summed either temporally (over a period of time) or at the same time (instantaneous), and if they push the voltage in the zone of the axon hillock to above threshold, it results in the generation of an action potential. The action potential travels through the axon, and once it reaches the terminal bouton of the axon, it triggers calcium influx into the cell, which causes neurotransmitter release. Neurotransmitter release may either be excitatory or inhibitory depending on the neurotransmitter released; for example, in the CNS, glutamate is the major excitatory neurotransmitter, whereas GABA is the major inhibitory neurotransmitter. They bind to the post-synaptic cell, which triggers the post-synaptic cell response. Note that this is just a general overview for neural transmission; some neurons may have different mechanisms of action.
How do electrical impulses go across synapses?
An electrial nerve impulse travels across a synapse by diffusion. The neurotransmitter substance from the pre-synaptic cleft travels across the synapse via diffusion. This is then received by receptors in the post synaptic cleft
What kind of stimulus (electrical or chemical) travels from the motor neuron to skeletal muscle?
This is done through a neurotransmitter. So the answer is chemical.
What happens to matter when sound travels through it?
It vibrates.
In what order does a message travel through the neuron?
A message travels through a neuron in the following order: dendrites receive the signal, the signal is passed through the cell body (soma), travels down the axon, and finally reaches the synaptic terminals where it is transmitted to the next neuron.
What do you call the chemical released by the axon that travels across a synapse and binds on the dendrites of the other neurons or body cells?
The chemical released by the axon that travels across a synapse and binds to dendrites or cells is called a neurotransmitter. Neurotransmitters play a crucial role in transmitting signals between neurons and regulating various physiological processes in the body.
What happens each time a ball travels through a wicket?
it becomes bowled and its out
What happens to the temperature of water as it travels through the water cycle?
It changes and stuff.
What happens when light passes through vacuum?
it travels at c (speed of light in a vacuum)
What happens to speed of light when travel through plastic?
When light travels through anything that is not a vacuum, it will usually slow down.
