Autonomics Flashcards
External carotid sympathetic actions to face
Salivary glands, sweat glands, and blood vessels
Internal carotid sympathetic actions to the nasal cavity and oral cavity
Blood vessel and mucus glands
Internal carotid sympathetic actions to the orbit
Dilate the pupil and keep the eyelid elevated
4 symptoms of Horner syndrome
- ) Pupillary constriction
- ) Ptosis
- ) Anhydrosis
- ) Flushing
In general, where does the greater splanchnic nerve synapse?
The celiac ganglion
What are the 4 abdominal prevertebral ganglia?
- ) Celiac ganglion
- ) Superior mesenteric ganglion
- ) Aorticorenal ganglion
- ) Inferior mesenteric ganglion
In general, where does the lumbar splanchnic synapse?
The inferior mesenteric ganglion
Whats weird about the innervation of the suprarenal glands?
The synapse occurs directly on the secretory cells of the medulla, which act as neurons.
They traverse both the paravertebral ganglia and prevertebral ganglia
The parasympathetics are carried by what cranial nerves and splanchnics
CN III, VII, IX, X
Pelvic splanchnics
Where do the vagus and pelvic splanchnics terminate?
The wall of the organ
Where does the vagus nerve stop?
The splenic flexure
What are the 4 ganglia in the head?
Ciliary, otic, pterygopalatine, and submandibular
What CN synapses at the ciliary ganglia?
CN III
What CN synapses at the otic ganglia?
CN IX
What CN synapses at pterygopalatine and submandibular ganglia?
CN VII
What is the parasympathetic function of the ciliary ganglia?
- ) Constrict the pupil
- ) Accomodation
- ) Lacrimal gland (tears)
What is the parasympathetic function of the glands of the mouth
Serous secretions
Where does the pterygopalatine ganglia send nerves?
The nasal area and palate
What salivary gland does the otic ganglia go to?
parotid
What salivary glands does the submandibular ganglia go to?
submandibular and sublingual
Where is the thoracic pain line?
T4-T5
What does pain above the thoracic pain line travel with?
Parasympathetics (vagus)
Foregut structures spinal levels for pain
T6-T9
Where do foregut organs generally produce pain?
In the epigastric region
