parasympathetic nervous system and sympathetic nervous system
purpose of the autonomic nervous system - 🧠ANSWER ✔✔exerts control
over the functions of many organs and tissues in the body

,Location of efferent fibers - 🧠ANSWER ✔✔have their cell bodies in the
spinal cord
Where doe efferent fibers reach? - 🧠ANSWER ✔✔the sympathetic ganglia
on both sides of the vertebral column
Where do the parasympathetic efferents reach? - 🧠ANSWER ✔✔on the
ganglia at or near the organs
function of sympathetic nervous system - 🧠ANSWER ✔✔"Fight or Flight"
