Parasympathetic Viscerosomatic Reflexes (from OMT review 3rd edition figure 10.4) Flashcards
Organ:
Pupils
CN III aka Oculomotor
(midbrain)
Ciliary ganglion
Organ:
Lacrimal and Nasal glands
CN VII aka Facial
(pons)
Sphenopalatine ganglion
Organ:
Submandibular and Sublingual glands
CN VII aka Facial
(pons)
Submandibular ganglion
Organ:
Parotid gland
CN IX aka Glossopharyngeal
(medulla)
Otic ganglion
Organ:
All viscera above the diaphram
CN X aka Vagus
(medulla)
Organ:
Upper and Middle GI
- lower 2/3 of esophagus to end of transverse colon (splenic flexure)
(stomach, liver, gallbladder, spleen, pancreas/duodenum, jejunum, ilium, ascending colon, transverse colon)
CN X aka Vagus
(medulla)
Organ:
Lower GI
- descending colon, sigmoid, and rectum
Pelvic Splanchnic Nerves
S2-S4
Organ:
Proximal GU
- Kidneys and Upper ureter
CN X aka Vagus
(medulla)
Organ:
Distal GU
- Lower ureter and Bladder
Pelvic Splanchnic Nerves
S2-S4
Detrusor muscle relaxation*
*Parasympathetic nerves from the S2, S3 and S4 levels of your spinal cord cause the upper part of your bladder to contract and your bladder neck to relax, assisting in the process of micturition (urination).
Organ:
Ovaries and Testes
CN X aka Vagus
(medulla)
- The ovaries and testes descend from higher in the posterior abdominal wall, therefore their innervations are from the vagus.
- All other reproductive structures are innervated by the pelvic splanchnic
Organ:
All reproductive organs except Ovaries and Testes
(uterus, prostate, genitalia)
Pelvic Splanchnic Nerves
S2-S4
Parasympathetic = “point” (erection)
- The ovaries and testes descend from higher in the posterior abdominal wall, therefore their innervations are from the vagus.
- All other reproductive structures are innervated by the pelvic splanchnic
