________ neurons transmit impulses FROM the Central Nervous System (CNS) TO the
muscles and glands. - ANS-Motor
The ___________ neurons run from various types of stimulus receptors to the CNS and carry
information such as touch, odor, taste, or vision. - ANS-Sensory
When a stimulus reaches a certain threshold, it triggers an____________ ________________.
When that occurs, sodium (Na+) ions rush into the cell through channels to the cell interior, and
the cell is becoming depolarized. - ANS-Action potential
What must be present and sufficient for an action potential to occur?
1.
2. - ANS-Amount of current and length of time its applied
When sodium (Na+) ions rush into the cell, and once sodium equilibrium is reached,
_____________ _____ ions want to leave the cell. - ANS-K+ (Potassium)
List reasons why Low back fibers are not easily available for stimulation: - ANS-Smaller area
related to the legs
Dorsal column are smaller and fewer

________________ is highly conductive and tends to disperse the electrical field. -
ANS-Cerebral Spinal Fluid (CSF)
, The dorsal CSF is the thickest in the mid to upper _______________ region due to the kyphotic
curve. - ANS-Thoracic Region
especially T5-T6
Nerve fibers ___________ in size as they ascend the cord. - ANS-decrease
A dermatome is defined as: - ANS-Area of skin inverted by a single dorsal root.

What vertebral segment is generally the last rib? - ANS-T12
What vertebral level is associated with the iliac crest? - ANS-Lumbar, generally around L4-L5
The larger nerve fibers, the Aα and Aβ fibers, carry information related to individual muscle
sense and relative position, which is also called ________________________. -
ANS-Proprioception
Define Nociceptive Pain. - ANS-Specialized nerve cell that detect noxious stimuli or things that
could damage the body.
Define Neuropathic Pain. - ANS-Develops when the nervous system isnt working properly due
to disease or injury.
