Sensations
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.
plasma membrane
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
This process is called transduction. It involves the conversion of physical stimuli from the environment into electrical signals that can be understood by the nervous system. This occurs through the activation of specific sensory receptors located throughout the body, such as in the eyes, ears, skin, and taste buds.
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.
both are plasma membrane receptors located at the cell surface's membrane. both are proteins that are hydrophilic and therefore cannot cross the lipid bilayer and requires second messengers to communicate with the nucleus of cells. activation of the receptors will activate other molecules in the activating cascades and the numbers of affected molecules will increase geometrically. however, activation of such receptors will cause desensitization/adaptation of the receptors themselves. the disability to desensitize can result to serious diseases such as cancer.

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.
