Where are receptor neurons found

Current topics in developmental biology, 2015.D 2 receptors are found not only on dopaminergic neurons (on the soma, dendrites and nerve terminals), where they function as inhibitory autoreceptors activated by locally released dopamine, but also on glutamatergic, gabaergic and cholinergic nerve terminals (see de mei et al., 2009).Where are gaba receptors found in the body?Neurotransmitter receptors are present on both postsynaptic neurons and presynaptic neurons with the former being used to receive neurotransmitters and the latter for the purpose of preventing further release of a given neurotransmitter.If a neurotransmitter bumps into its corresponding receptor, they will bind and can trigger other events to occur inside the cell.In flies the cells that detect the tastants are bona fide neurons rather than neuroepithelial cells found in mammalian taste buds.

The endogenous opioids are dynorphins, enkephalins, endorphins, endomorphins and nociceptin.the opioid receptors are ~40% identical to somatostatin receptors (sstrs).Sensory neurons can have either (a) free nerve endings or (b) encapsulated endings.They fire action potentials when odorant molecules cause movement of olfactory hair cells.
