function. Frontal: Controls higher level executive
functions.
Parietal: Receives sensory information
from body receptors.
Occipital: Interprets visual input.
Which of the following Dorsal root ganglion

contains the cell bodies of
afferent neurons?
Describe the function of the The sympathetic nervous system (SNS) is
sympathetic nervous system often referred to as the "fight or flight"
when a threat is present. system. When in immediate danger,
muscles require a steady, increased
supply of glucose and oxygen for
muscular contraction. The SNS
accelerates the heartbeat, dilates the
bronchi, and increases the respiratory
rate. This supplies the increased need for
oxygen throughout the body. The SNS
also causes the liver to deliver more
glucose for the body's increased
metabolic needs. Sympathetic activation
inhibits the digestive tract because
digestion is not an immediate necessity
when in danger or under attack.
