Sympathetic innervation to the pelvis muscles- function
Stop movement by causing sphincters to contract
Sympathetic innervation to pelvis is carried by
Sacral splanchnic nerves
Functions of afferents that accompany the sympathetics of the pelvis
Register stretch sensation superior to the pelvic pain line
Parasympathetic innervation to pelvis muscles- function
Propel by organ wall contraction and sphincter relaxation
Parasympathetic innervation to pelvis is carried by
Pelvic splanchinic nerves
Functions of afferents that accompany parasympathetics of the pelvis
Unconscious reflexes
Pain below the pelvic pain line travel retrograde with parasympathetics
Lumbosacral trunk extends from
L4-S4
