Special senses are found
on specific sensory organs
conscious or subconscious awareness of change in external or internal environment is

requirements for sensation
conscious awareness is
perception
decreased receptor response with prolonged stimulation is
adaptation
nociceptors, thermoceptors, tickle, itch, and light touch receptors are
free nerve endings
mechanoreceptors or deep touch and vibration are
encapsulated nerve endings
osmoreceptors, baroreceptors, chemoreceptors, proprioreceptors, photoreceptors are
special cells

Somatic Pain
Dull or aching pain that develops more slowly over time and travels over C pain fibers (chronic/slow)
Visceral Pain
regenerative cells for normal growth, development, and repair/healing
Basal cells
