general body senses (touch, temperature and pain), associated with most parts of the body.
Associated with specialized organs in the body; sight hearing/equilibrium, taste, touch, smell
diminished sensitivity as a consequence of constant stimulation
respond to chemicals
sense damage or the potential for damage
respond to changes in temperature
respond to touch, pressure, vibration, stretch, and itch
The light-sensitive cells in the retina- the rods and cones.
Functions of all receptors
1) to detect something
2) to start an impulse on a sensory neuron
Free nerve endings
found in the dermis and internal organs
sense light touch and texture, only found in the dermis
found in the dermis and internal organs, sense pressure and vibration
pain felt in an area other than the one being damaged
feeling pain in a body part the one does not have anymore, because pain is sensed in the brain.
the ability to sense the position and location and orientation and movement of the body and its parts; uses stretch receptors
Stretch receptors on the muscles, help to make fine adjustments while walking
Golgi tendon organs
Stretch receptors in tendons, help make fine adjustments while walking
