Where are neurotransmitter receptors located?


Quick Answer

Neurotransmitter receptors are located on the cell surface of specific ligands, post-synaptic cells and sometimes pre-synaptic cells. While they are most commonly found in the nervous system, they are also present on some muscle and immune tissues.

Full Answer

Neurotransmitter receptors receive signals and excite or inhibit a cellular process in response. As each neuron connects with more than 15,000 other neurons, the majority of neurotransmitter receptors produce excitatory responses. After receiving a neurotransmitter, the receptor usually triggers an action potential, which then leads to a cellular process elsewhere. Most are G protein-coupled receptors, which span across the cell's surface more than once.
