1temperature receptors include two group of free endings:
heat and cold receptors
2temperatures near __ stimulate pain receptors
45 degree Celsius
3temperatures below __ also stimulate pain receptors and produce a freezing sensation
10 degree Celsius
4pain receptors consist of __ that are stimulated when tissues are damaged, and adapt little, if at all
free nerve endings
5many stimuli affect pain receptors such as _ and _ deprivation
chemicals and oxygen
6are the only receptors in the viscera that produce sensations
visceral pain receptors
7occurs because of the common nerve pathways leading from skin and internal organs
referred pain
8fibers conducting pain impulses away from their source are either ____
acute pain fibers or chronic pain fibers
9are thin, myelinated fibers that carry impulses rapidly and cease when the stimulus stops
acute pain fibers
10are thin, unmyelinated fibers that conduct impulses slowly and continue sending impulses after the stimulus stops
chronic pain fibers
11are processed in the gray mater of the dorsal horn of the spinal cord
pain impulses
12are conducted to the thalamus, hypothalamus, and cerebral cortex
pain impulses
13a person become aware of the pain when impulses reach the _
thalamus
14judges the intensity and location of the pain
cerebral cortex
15Other areas of the brain regulate the flow of pain impulses from the spinal cord and can trigger the release of _ and _ which inhibit the release of pain impulses in the spinal cord.
enkephalins and serotonin
16released in the brain provide natural pain control
endorphins
17are associated with fairly large and complex structures located in the head
special senses

static equilibrium
dynamic equilibrium
sight
19olfactory receptors are _
chemoreceptors
20the senses of _ and _ operate together to aid in food selection
