Adrenergic receptors
what are the characteristics of action potentials
Excitatory neurotransmitter
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.
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.
They connect to the transverse tubules of the the sarcolemma at triad junctions.
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.
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".

SEROTONIN is a neurotransmitter that inhibits pain by blocking pain causing chemicals out of their receptor sites
Dopamine receptor agonists are a class of drugs with similar actions to dopamine, a neurotransmitter that occurs naturally in the brain.
what are the characteristics of action potentials
beta neuron
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.
