What is a molecule such as a neurotransmitter or a hormone that binds to a receptor called?
what are the characteristics of action potentials
Neurotransmitters find their way to and subsequently trigger firing of that neuron?
Excitatory neurotransmitter
Neurotransmitters are released in a synapse and bind to?
a receptor structure in a ligand-gated sodium-ion pore. The receptor is like a cave which is an outer part of a protein structure which also has a tunnel which can be open or closed, and the presence of the neurotransmitter causes the tunnel (pore) to open.
What is the difference between endomysium and sarcolemma?
Sarcolemma is the equivalent of the plasma membrane of the muscle fiber (aka muscle cell). The endomysium is a connective tissue that bounds around the sarcolemma.
What connects the sarcolemma and the sarcoplasmic reticulum?
They connect to the transverse tubules of the the sarcolemma at triad junctions.
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.
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".
The same receptor can have different effects depending on the properties of the?
neurotransmitter
Which neurotransmitter inhibits pain transmission?
SEROTONIN is a neurotransmitter that inhibits pain by blocking pain causing chemicals out of their receptor sites
What are dopamine receptor agonists?
Dopamine receptor agonists are a class of drugs with similar actions to dopamine, a neurotransmitter that occurs naturally in the brain.
What is a molecule such as a neurotransmitter or a hormone that binds to a receptor called?
what are the characteristics of action potentials
What adrenergic neurotransmitter receptor plays a role in heart activity?
beta neuron
What mimic or enhance the effects of a neurotransmitter on the receptor sites of the next cell increasing or decreasing the activity of that cell?
agonists Chemical substances that mimic or enhance the effects of a neurotransmitter on the receptor sites of the next cell, increasing or decreasing the activity of that cell. Drug that enhances the effects of a particular neurotransmitter.
A good analogy for the way in which a neurotransmitter binds to receptor sites is?
a key fitting in the lock of a door
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.
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
Neurotransmitters find their way to and subsequently trigger firing of that neuron?
Excitatory neurotransmitter
