What Receptor sites on the membrane of a neuron's dendrites receive?
Receptor sites on the membrane of a neuron's dendrites receive neurotransmitters, which are chemical messengers released by neighboring neurons. When these neurotransmitters bind to their specific receptors, they can initiate changes in the neuron's electrical state, leading to either excitatory or inhibitory signals. This process is essential for synaptic transmission and plays a crucial role in neural communication and processing information.
You could locate receptor sites involved in transmiting a nerve impulse by finding the?
Synapse? Dendrite? Dendritic spine? Or, "You could maybe a better answer to your question get if you re-stated it less confusingly as?" ie, perhaps, "Where are the receptor sites involved in transmitting a nerve impulse LOCATED?"
A synapse consist of?
A synapse is the connection between two neurons. It consists of the synaptic cleft (the physical gap between one neuron's axon and the other's dendrite). Neurotransmitters cross the gap from the axon to the dendrite and affect whether the next neuron fires.
What are viral receptor sites?
Viral receptor sites are specific locations on the surface of host cells where viruses attach to facilitate entry. These sites typically consist of proteins or glycoproteins that the virus recognizes and binds to, allowing it to penetrate the cell membrane. The interaction between viral proteins and these receptor sites is crucial for the viral infection process, determining the host range and tissue tropism of the virus. Understanding these receptor interactions can aid in the development of antiviral therapies and vaccines.
Do neurotransmitters pass directly from the axon to the dendrite?
No, neurotransmitters are released from the axon terminal into the synaptic cleft between the axon terminal and the dendrite. They then bind to receptor sites on the dendrite to transmit signals from one neuron to another.

What happens when a substance gets into a neuron?
When a substance enters a neuron, it can bind to receptor sites on the neuron's membrane, triggering a cascade of events within the neuron. This can lead to changes in the neuron's electrical activity, release of neurotransmitters, or alterations in gene expression, ultimately affecting the neuron's function.

No, neurotransmitters are released from the axon terminal into the synaptic cleft between the axon terminal and the dendrite. They then bind to receptor sites on the dendrite to transmit signals from one neuron to another.
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.
Neurotransmitters find their way to and subsequently trigger firing of that neuron?
Excitatory neurotransmitter
When neurotransmitters bind to or attach to receptor sites the probability of the postsynaptic neuron firing an action potential?
... Depends entirely on the post-synaptic neuron. If it is an inhibitory synapse (often located on the actual body of the dendrite or soma), then the probability of that post-synaptic neuron firing DECREASES. The reverse is true if it is excitatory; the synapse (more likely located on a dendritic spine) will more likely induce the post-synaptic neuron to fire an action potential.
What receptor sites does opiates lock into?
endorphins
What is an adrenergic receptor?
An adrenergic receptor is any of several sites in the surface membranes of cells innervated by adrenergic neurons.
How do you locate receptor sites when transmitting a nerve cell?
Synapse
Where are Receptor sites on a neuron primarily found?
dendrites only
Opiate drugs occupy the same receptor sites as?
endorphine
