descending tracts correct answers carry motor commands to spinal cord
Spinal Cord Structure and Function correct answers • The spinal cord is a continuation of the
brain stem through the vertebral column providing a two way path of communication between
the brain and rest of the body. It also is a reflex center (integrator)
◦ Contains gray matter shaped like "butterfly" or "H" in the middle surround central spinal canal
while white matter surrounds this
◦ Gray matter mostly cell body, white matter myelin from tracts
• Two bulges in the spinal cord, one in the cervical and one in the lumbar region
31 pairs of spinal nerves correct answers 8 cervical
12 thoracic

5 sacral
1 coccygeal
Human Nervous System correct answers central nervous system and peripheral nervous system
somatic nervous system correct answers the division of the peripheral nervous system that
controls the body's skeletal muscles
autonomic nervous system correct answers The part of the PNS that controls the glands and the
muscles of the internal organs.
