in the cell membrane
depends on the receptor. A lot are in the cell membrane but some may be cytoplasmic or even nuclear depending on the solubility of the ligand and how it enters the cell.
Sensory receptors for cold are located in the dermis, the are formally called free nerve endings.
pain receptors
cochlea
Auditory receptors are located in internal ears. The vestibulocochlear nerve carries the signal from internal ear to brain.

where are receptors for non-steroid hormones located
In vertebrates the olfactory receptors are located in the cilia of the olfactory sensory neurons. In insects olfactory receptors are located on the antennae and other chemo sensory organs.
Sensory receptors for cold are located in the dermis, the are formally called free nerve endings.
Pain Receptors
pain receptors
General sensory receptors such as light touch and temperature receptors are located over the entire surface of the body. There are no specific areas where these receptors are located.
cochlea
The intracellular receptors differ from membrane receptors based on their location. Membrane receptors are usually on the plasma membrane but the intracellular receptors are found inside the cell.
Receptors for the various neurotransmitters are located on both the presynaptic and postsynaptic nerve terminals of the neuron.
5-HT receptors are the receptors for serotonin. They are located on the cell membrane of nerve cells and other cell types in animals.
