What functions as a neurotransmitter?
When impulses reach a synapse they trigger the release of chemicals called neurotransmitters. Molecules of the neurotransmitter cross the synapse and stimulate the receiving neuron to fire an impulse of its own as wave like movements of ions. They may also actively inhibit a receiving neuron from firing.
Light sensitive worker needed to receive visual images and transmit impules to the brain?
the image passes from neuron to neuron through neurotransmitters until it reaches the brain, where the neurotransmitters are read
What part of a neuron contains neurotransmitters?
Neurotransmitters are used to send messages from cell to cell, usually neuron to neuron. Neurotransmitters are released from the pre-synapse, which is at the axon terminus. These neurotransmitters are picked up by the post-synapse on the receiving cell. These post-synapses are located on structures called dendrites or on the cell body.
Why would a lack of neurotransmitters change the function of the brain?
signals travel from neuron to neuron through neurotranmitters
Where are neurotransmitters found in the body?
Neurotransmitters are found in the axonal terminals of a neuron in the peripheral nervous system (or PNS). An example of a neurotransmitter is neurepinephrin.
A neuron reaches its trigger point when?
Action potential is nerve impulse triggered when a neuron reaches its threshold, or trigger point for firing. Threshold trigger point for a neuron's firing about negative 50 millivolts.
What is the relationship between the action potential and the synapse?
A synapse and an action potential have a flip-flopping cause and effect relationship, in that an action potential in a presynaptic neuron initiates a release of neurotransmitters across a synapse, which can then subsequently potentially trigger an action potential in the axon of the postsynaptic neuron, which would then cause release of neurotransmitters across a following synapse.
Transmit neural messages from neuron to neuron?
Neurons send messages by way of chemical signalers called neurotransmitters. An activated neuron releases neurotransmitters and their collective action can stimulate another neuron. These individual firing sequences are called action potentials.
Certain mental problems are thought to be caused by not having enough neurotransmitters. Why would a lack of neurotransmitters cause problems?
Neurotransmitters send signals from neuron to neuron
Why would a lack of neurotransmitters cause problems?
neurotransmitters send signals from neuron to neuron
What effects do neurotransmitters from the neuron have on the next neuron?
The neurotransmitters from one neuron have direct effect on the next neuron. They are channels that are used to transmit messages in the nerves.
What functions as a neurotransmitter?

Molecules of the neurotransmitter cross the synapse and stimulate the receiving neuron to fire an impulse of its own as wave like movements of ions. They may also actively inhibit a receiving neuron from firing.
What happens when neurotransmitters communicate an excitatory message to the postsynaptic neuron?
When neurotransmitters communicate an inhibitory message to the postsynaptic neuron:
Neurotransmitters categorized as inhibitory are expected to?
Inhibitory neurotransmitters prevent the firing of neurons by binding with certain receptors, causing the influx of chloride ions to hyperpolarize the neuron. When this happens, it requires a much larger excitatory signal to override the inhibitory effects in order to allow the neuron to fire.
Neurotransmitters released by 1 nerve cell are received by?
Neurotransmitters released by 1 nerve cell are received by another neuron. The receptor of a postsynaptic neuron receives the neurotransmitters.
Are the part of the neuron where chemicals called neurotransmitters are released?
The synaptic cleft is the area of the neuron that secretes neurotransmitters.
What bridge the gap between a neuron sending a message and the neuron receiving it?
neurotransmitters
