- somatic senses (touch, pressure, temp, pain) |
Somatic Senses
. Sensory Nerve Fibers - epithelial tissue, pain and pressure
2. Meissner's corpuscles - hairless areas of skin (lips, fingertips)
3. Pacinian corpuscles - deep pressure (tendons, joints)
Temperature Senses (warm and cold receptors)
Sense of Pain - pain receptors do not adapt, prompts a person to take action to avoid stimulus

Temperature Senses (warm and cold receptors)
Sense of Pain - pain receptors do not adapt, prompts a person to take action to avoid stimulus
Visceral Pain - occurs in visceral tissues such as heart, lungs, intestine
Referred pain - feels as though it is coming from a different part (heart pain may be felt as pain in arm or shoulder)
Acute Pain - originates from skin, usually stops when stimulus stops (needle prick)
Chronic Pain - dull aching sensation
Regulation of Pain impulses
Inhibitors of Pain (natural brain chemicals can be mimicked by drugs such as morphine)
Enkephalins / Serotonin / Endorphins
