Found in the muscles, tendons, ligaments, and connective tissue coverings of the muscles and bones. Helps the brain know the location of the body parts
Chemoreceptors
Responds to chemicals in solution *Taste, smell and blood chemicals
Nociceptors
Pain receptors *responds to potentially damaging stimuli
Thermoreceptors
Responds to changes in temperature
Mechanoreceptors
Detects touch, pressure, vibrations and stretch
Photoreceptors
Responds to light energy *Mainly found in eyes
