Sensory endorgans compose the peripheral endings of all Dorsal Root Ganglial neurons and to some cranial nerve ganglion cells. Specialized dorsal ganglion root sensory neurons of cranial nerves end on receptor cells for taste, vestibular and auditory system. These receptor cells liberate synaptic transmitter onto the cranial nerve ending. Visual and olfactory systems are special considerations to be described later.

Receptors endings of sensory neurons fall into two classes: those for extrinsic environmental stimuli and those from intrinsic energy generated by the body. Each receptor organ is specialized for the sensory modality by connective tissue and supporting cell organizations that surround each receptor axon (teledendron).
Skeletal receptors for movement reflexes use stretch receptors and tendon organs of the DRG’s. Others are joint receptors and deep and supereficial pressure receptors.
Surface contact (touch), deep pressure, pain, and temperature receptors.
Visceral receptors: blood pressure, CO2, gut , bladder, etc
