What else can I help you with?
Neurotransmitters find their way to and subsequently trigger firing of that neuron?
Excitatory neurotransmitter
Receptor sites are found where?
Receptor sites are primarily found on the surface of cells, embedded in their membranes. These sites interact with specific molecules, such as hormones, neurotransmitters, or drugs, allowing the cell to receive and respond to various signals. Additionally, receptor sites can also be present in intracellular compartments, where they play roles in signaling pathways within the cell.
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.
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.
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?"
What part of the neuron was called the post-synoptic part of the neuron in humans?
The post-synaptic part of a neuron in humans is typically referring to the dendrites and cell body (soma). These structures receive signals from other neurons via neurotransmitters released at synapses.
What forms receptor sites on the post synaptic cell membrane?
Protein molecules on the post-synaptic cell membrane form receptor sites that bind with neurotransmitters released from the pre-synaptic neuron. This binding triggers downstream signaling pathways within the post-synaptic cell, leading to various cellular responses.
In the lock and key analogy for neurotransmitters the lock refers to the?
In the lock and key analogy for neurotransmitters, the lock refers to the receptor sites on the postsynaptic neuron. Just like a key fits into a specific lock, neurotransmitters bind to their corresponding receptors, triggering a response in the receiving neuron. This analogy illustrates the specificity of neurotransmitter-receptor interactions, which are crucial for effective communication between neurons.
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.
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 receptor sites does opiates lock into?
endorphins
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.
