They are nerves. These nerves tell us exactly what we feel, and then send that information to the brain.
Sensory (afferent) neurons
Sensory neurons are the type of neurons that have the ability to monitor the environment. They are specialized to detect stimuli from the external or internal environment and transmit this information to the brain for processing.

In the skin, neurons that detect stimuli are called mechanoreceptors for touch, nociceptors for pain, and thermoreceptors for temperature. In the eyes, neurons that detect light stimuli are called photoreceptors, specifically rods and cones located in the retina.
sensory neurons
Sensory receptors detect changes in the environment known as stimuli. These receptors are specialized cells that send signals to the brain or spinal cord in response to specific types of stimuli such as light, sound, pressure, or chemical signals.
Auditory sensory neurons are specialized to detect stimuli from the environment which triggers the neuron to transmit a message to the central nervous system. These stimuli are both voluntary and involuntary.
Somatic sensory neurons detect stimuli from the skin, muscles, and joints. Visceral sensory neurons detect stimuli from internal organs such as the heart, lungs, and intestines. Both types of neurons transmit sensory information to the central nervous system for processing.
The special cells of the sense organs that receive stimuli from the environment are called receptors. The receptors detect different changes in the surrounding envronment and stimulate the neurons to perform the proper tasks.
Sensory Neurons- they detect stimuli and transmit signals to the brain and the spinal cord, which are both made up of interneurons
Special sensory neurons in sense organs that receive stimuli from the external environment.
