1
Q

Components of the peripheral nervous system

A

autonomic (involuntary) and somatic (voluntary - skeletal muscle primarily)

2
Q

components of the autonomic nervous system

A

sympathetic and parasympathetic

3
Q

divisions of autonomic nerves

A
  • sympathetic: thoracolumbar (EXITS from the thoracic and lumbar regions of the spine)
  • parasympathetic: craniosacral (EXITS from the cranial and sacral areas)
  • *exits from means that’s where the cell bodies are
4
Q

identifying characteristics of autonomic vs. somatic nerve circuits

A

autonomic system always has at least 2 nerves with a ganglion
somatic may only have one nerve that goes to skeletal muscle

5
Q

dual innervation

A

different nerve systems go to multiple organs, but usually do NOT innervate the same cell type, which is how they cause different responses in different organs
