Which neurotransmitter regulates muscle tone and emotional responses?
All of the following are true about grey and white matter in the spinal cord, except:
Regions called horns contain grey matter
Grey matter passes information up and down the spinal cord
White matter is arranged in columns
Tracts consist of white matter
Each dermatome sends sensory signals through
A single left spinal nerve or right spinal nerve, but not both
A single nerve plexus
A segment of the spinal cord that corresponds to a plexus
A single pair of spinal nerves
Why can spinal reflexes occur more quickly than premeditated actions?
Reflexes utilize different motor neurons
Reflexes actions do not involves the central nervous system
The signal for spinal reflex is processed in the spinal cord rather than the cerebrum
Sensory information travels faster during a reflex action
