What are the molecules that are similar enough to a neurotransmitter to bind to its receptor sites on a dendrite and mimic that neurotransmitter's effects called?
Molecules that are similar enough to a neurotransmitter to bind to its receptor sites on a dendrite and mimic its effects are called agonists. These can be naturally occurring substances or synthetic drugs that activate receptor sites, leading to similar physiological responses as the original neurotransmitter. Examples include morphine, which mimics endorphins, and nicotine, which mimics acetylcholine.
What is the advantage of having multiple receptor subtypes for a neurotransmitter?
Multiple receptor subtypes allow for more "fine-tuned" neuromodulation of a given "signal" in a neural network. Each receptor subtype typically has a different binding affinity for the given neurotransmitter. Therefore, the neurotransmitter may bind more strongly or more weakly to one subtype over another. This is most likely an effect of genetic variation, as the genes coding for the protein(s) present in the receptor slightly vary from subtype to subtype, yet still allow for binding by the neurotransmitter ligand.
What determines whether a neurotransmitter will have an inhibitory excitatory effect?
How a neurotransmitter interacts with the receptors determines its effects. They activate receptors to perform specific functions in the body.the type of receptor
What is the relationship between receptor and a neurotransmitter?
The relationship between a receptor and a neurotransmitter is fundamental to neural communication. Neurotransmitters are chemical messengers released by neurons that bind to specific receptors on the surface of target cells, such as other neurons or muscle cells. This binding triggers a response in the target cell, which can lead to various effects, such as excitation or inhibition of neuronal activity. The specificity of this interaction is crucial for proper signal transmission and modulation within the nervous system.
What does the neurotransmitter bind to after it moves across the synaptic cleft?
The neurotransmitter binds to specific receptors on the postsynaptic neuron's membrane. This binding triggers a series of events that can either excite or inhibit the postsynaptic neuron, ultimately influencing its activity.
What adrenergic neurotransmitter receptor plays a role in heart activity?
beta neuron
Which structure is like a locked door that only certain neurotransmitter key can unlock?
Since only 1 neurotransmitter fits in the receptor sites, you can say that the receptor sites is the locked door waiting for the neurotransmitter "keys".
How do benzodiazepines interact with the GABA receptor to produce their therapeutic effects?
Benzodiazepines enhance the activity of the neurotransmitter GABA at its receptor in the brain, which leads to a calming and sedative effect. This interaction helps to reduce anxiety, promote relaxation, and improve sleep quality.
Which neurotransmitter inhibits pain transmission?
SEROTONIN is a neurotransmitter that inhibits pain by blocking pain causing chemicals out of their receptor sites

Examples include morphine, which mimics endorphins, and nicotine, which mimics acetylcholine.
What is a molecule such as a neurotransmitter or a hormone that binds to a receptor called?
A molecule such as a neurotransmitter or hormone that binds to a receptor is called a ligand. This binding triggers a biological response in the target cell, influencing its function.

What are holes in the surface of the dendrites or certain cells of the muscles and glands that are shaped to fit only certain neurotransmitters?
Neurotransmitter receptor sites on ligand-gated ion pores.
A good analogy for the way in which a neurotransmitter binds to receptor sites is?
a key fitting in the lock of a door
