Bodily senses Flashcards
There are at least six distinct bodily or somatic senses:
touch
temperature
pain
position/motion
balance, and
interoception (perception of bodily sensations).
The top layers of skin have receptor cells that are sensitive to different tactile qualities—some to shape, some to grooves, some to vibrations and movements.

somatosensory cortex
A complex emotional and sensory experience associated with actual or potential tissue damage.
Pain
When people who have lost a limb feel pain in the missing arm or leg. Such cases dramatically show how pain is not just a direct result of tissue damage, but an experience in the brain as well.

send signals to the spinal cord and then to the brain, signaling that damage has occurred.
Nociceptors
A somewhat surprising finding is that some of the same brain regions and neurochemicals activated when we experience physical pain are also activated during emotional pain—especially when we are rejected by others or see others receive shocks
Even more fascinating, the same brain regions ———————— are activated whether we experience pain directly or observe someone else get hurt

When we are hurt, our bodies respond by releasing these substances

are very important survival-related senses, for they govern our choices about what we take into our bodies.
