What are the chemicals that are released at an axon terminal and can either excite or inhibit other neurons called?
Neurotransmitters are the chemicals released at an axon terminal that can either excite or inhibit other neurons. They help transmit signals across the synapses between neurons in the nervous system. Examples of neurotransmitters include dopamine, serotonin, and GABA.
How can neurotransmitters inhibit or excite a postsynaptic neurons?
Neurotransmitters can inhibit a postsynaptic neuron by binding to inhibitory receptors, which can open channels that allow negatively charged ions like chloride to enter the neuron, making it more negative and less likely to fire. On the other hand, neurotransmitters can excite a postsynaptic neuron by binding to excitatory receptors, leading to the opening of channels that allow positively charged ions like sodium to enter the neuron, depolarizing it and increasing the likelihood of firing an action potential.
Neurons communicate with other neurons and stimulate both?
Neurons communicate through electrochemical signals, known as action potentials, that allow them to relay information to other neurons. When a neuron stimulates another neuron, it triggers the release of neurotransmitters that can excite or inhibit the activity of the receiving neuron, influencing its firing potential. This communication is key in coordinating various functions in the brain and nervous system.
What is the most important function of endorphins?
Enable neurons to excite or inhibit each other
Where are the receptors for neurotransmitters located?
Neurotransmitter receptors are located on the postsynaptic membrane of neurons. When a neurotransmitter binds to its specific receptor, it can either excite or inhibit the postsynaptic neuron, thereby influencing the transmission of signals in the brain.

What happens after a neurotransmitter travels through the synaptic cleft?
After a neurotransmitter travels through the synaptic cleft, it binds to receptors on the receiving neuron, which can either excite or inhibit the receiving neuron's activity. This process helps transmit signals between neurons in the brain and nervous system.
What makes the cell body fire?
The cell body fires when it receives enough input signals, usually in the form of neurotransmitters from other neurons. These signals can excite or inhibit the cell body, changing its membrane potential until it reaches a threshold that triggers an action potential.
Neurotransmitters bind to specific proteins on the postsynaptic membrane called?
Neurotransmitters bind to specific proteins on the postsynaptic membrane called receptors. These receptors initiate a series of events that can either excite or inhibit the firing of the postsynaptic neuron.
Are neurotransmitters sometimes referred to as a key?
Yes, neurotransmitters are sometimes referred to as "keys" because they play a critical role in transmitting signals between nerve cells, or neurons. These molecules bind to specific receptors on the surface of neurons, which triggers a response in the receiving cell. Just like a key fits into a lock to open a door, neurotransmitters bind to receptors to either excite or inhibit activity in the brain and body.
Where are the receptors for neurotransmitters located?
Neurotransmitter receptors are located on the postsynaptic membrane of neurons. When a neurotransmitter binds to its specific receptor, it can either excite or inhibit the postsynaptic neuron, thereby influencing the transmission of signals in the brain.
Is it true that a post synaptic potential is a graded potential that is the result of a neurotransmitter released into the synapse between two neurons?
Yes, that is correct. A postsynaptic potential is a localized change in the membrane potential of a postsynaptic neuron in response to neurotransmitters binding to receptors on its membrane. This results in a graded potential that can either excite or inhibit the postsynaptic neuron's firing.
What happens at a synapses?
At a synapse, one neuron sends signals to another neuron through the release of chemicals called neurotransmitters. These neurotransmitters travel across the synapse and bind to receptors on the receiving neuron, which can either excite or inhibit the next neuron's activity. This communication between neurons plays a crucial role in transmitting information throughout the nervous system.
The effect of a neurotransmitter on the postsynaptic cell occurs when the neurotransmitter?
binds to specific receptors on the postsynaptic cell membrane, leading to changes in the cell's membrane potential. This can either excite or inhibit the postsynaptic neuron, influencing the likelihood of an action potential being generated. Ultimately, the effect of the neurotransmitter can influence the communication between neurons in the nervous system.
