General sense organs
Sense organs mainly for sensations such as pain, temperature, touch, and pressure
Mechanoreceptors
Cells that are activated by mechanical stimuli
Chemoreceptors
Cells that are activated by chemical stimuli
Unencapsulated
A "Naked receptor"
Proprioreceptor
Recptor in the muscles
Photoreceptors
Cells activated by light stimuli
General sense organs
Are distributed throughout the body and detect stimuli such as touch, pressure, temperature, position, and pain.

Proprioceptors
Specialized receptors found near the point of junction between tendons and muscles and others found deep within skeletal muscle tissue.
Encapsulated receptors
Nerve endings that have a type of connective tissue capsule surrounding their terminal or dendritic end.
Receptors
Receptors produce an electrical signal or nerve impulse. This impulse is conducted by a sensory nerve to the appropriate area of the brain, where the sensation is perceived and interpreted.
Ruffini's corpuscles
Sense touch and pressure
Meissner's corpusles
Sense of touch and low frequency vibration
Krause's end-bulbs
Sense of touch and possibly cold
Crude touch
Free nerve endings
Free nerve endings
Sense temperature
