Document Summary

*somatosenstaion enables our body to feel, to ache, to sense temperature, and know what the parts of the body are doing. Temperature of the limbs and the brain itself. *when stimuli because so intense that something may be damaging somatosenstaion is responsible of feeling pain. Differences of somatosenstaion to other sensory systems: receptors are distributed throughout the body rather than a specific area, responds to many kinds of stimuli rather than use a specific one: touch, temperature, pain and body positions. *in general the somatosenstaion includes all type of receptions exluding: vision, audition, taste, olfactory, and the vestibular sense of balance. *picture illustrates the two types of skin (hairy and glabrous) and the two skin layers (epidermis and dermis) and the different receptors. *mechanoreceptors are sensitive to physical distortion (like stretching). Pressure in the heart and blood vessels. Stretching of the digestive organs and urinary bladder.
