They are found in many tissues in the body, mainly in the skin. They are responsible for pain reception and are sometimes referred to as nociceptors.
The simplest type of sensory receptor is the free nerve ending, which is a bare dendrite ending of a sensory neuron that is sensitive to various stimuli like temperature and pain. These receptors are found throughout the body and respond quickly to changes in the environment.

Free nerve endings functions as cutaneous receptors ( is a sensory receptor present on dermis or epidermis ). Present in vertebrates for sense of pain. they are frequently found on skin. *Muscle spindles

tactile (Merkel) discs
The optic nerve.
Modified free-nerve endings in the deeper levels of the epidermis are found associated with tactile (Merkel) cells. These receptors are sensitive to light touch and pressure stimuli, providing information about tactile sensations to the brain.
The other name for the sensory nerve is sensory neuron. These are nerve cells that transmit sight, sound, and feelings.
