Nervous System Flashcards
Two main systems of the nervous system
Central nervous system & peripheral nervous system
Two components of Peripheral nervous system
somatic and autonomic
What does the somatic nervous system control
voluntary motor movements of skeletal of lined muscles
What does the autonomic nervous system control
involuntary movements
What are the primary focuses of the autonomic nervous system
maintain balance and homeostasis
What are the subdivisions of the autonomic nervous system
sympathetic and parasympathetic
Which system is “fight or flight”
sympathetic
Which system increases function with stress
sympathetic
The sympathetic nervous system releases what into the blood stream
hormones that increase heart rate, respiration, and blood pressure.
Which system response decreases restorative functions like digestion and elimination
sympathetic
What does the parasympathetic nervous system do
calms the body down from stress. Slows down heart rate, respiration, decreases blood pressure, and increases digestion and elimination
Which division of the autonomic system is healthy
parasympathetic
The command center of the body that includes the brain, retina, and spinal cord is the
central nervous system
This system consists of sensory neurons, ganglia, and nerves that connect the central nervous system to other parts of the body such as arms and legs
peripheral nervous system
This system has nerves that connect to the heart, lungs, stomach, intestines, bladder, and sex organs
autonomic nervous system
