| What are the parasympathetic nucleus and ganglion for glossopharangeal? What do the fibers innervate? |
|
Definition
Inf salivary nucleus (medulla) and the otic ganglion.
Parotid gland. |

Term
| Parasympathetic causes _________ of pupils and _______ of blood vessels? (generally) |
|
Definition
|
|
Term
| Sympathetic causes _________ of pupils and ________ of blood vessels? (generally) |
|
Definition
|
|
Term
| Splancnic nerves pass through the _________ and continue to reach their ________ ganglia. |
|
Definition
| sympathetic trunk (without synapsing), preaortic/prevertebral (along abdominal aorta) |
|
|
Term
| Name the four largest sympathetic ganglia from top to bottom. Which ones have white and which have grey communicans? |
|
Definition
1. Superior cervical ganglion - gray
2. Middle cervical ganglion - gray
3. Vertebral ganglion - gray
4. Cervicothoracic ganglion - white and gray |
|
|
Term
| How do sympathetic fibers get higher than the sup. cervical ganglion? |
|
Definition
| By following branches of the carotid. |
|
|
Term
| Horners syndrome is caused by? Results in? |
|
Definition
Lesion to sympathetic flow to head. Results in droopy eyelid, contracted pupil, and loss of sweating, and vasodilatation, all on the ipsilateral side.
(Think of sympathetic as opening all the stuff in your face up; eyelid, pupil, pores... basically redbull for the face) |
|
|
Term
| Path for sympathetic innervation to lower than L2. |
|
Definition
| Lateral horn cell body of (typically) L2 -> ventral root -> spinal nerve -> white ramus communicans -> sympathetic trunk -> to lower ganglion of sympathetic trunk [synapse] -> grey ramus communicans ->back to spinal nerve -> dorsal or ventral ramus |
|
|
Term
| All autonomics have two cell bodies, one in CNS from neural ectoderm and the other in PNS from neural crest, except? |
|
Definition
| Autonomics to the adrenal medulla use a one neuron pathway. (The adrenal medulla is derived from neural crest and can be thought of as a big postganglionic neuron in a developmental sense). |
|
|
Term
| Sympathetic origin on spinal cord? |
|
Definition
| Grey matter lateral horn of T1-L2 |
|
|
Term
| Where does the vagus nerve send parasympathetic fibers, and where are the ganglia? |
|
Definition
| It sends para fibers to the vicera of the thorax, foregut, & midgut. It's ganglia are called terminal ganglia and are typically in the wall of the organ innervated. |
|
|
Term
| What do the sacral parasympathetics innervate. |
|
Definition
| The hindgut that the vagus doesn't get. Also referred to as the pelvic splanchnic nerves. |
|
|
Term
| How do para fibers from the glosspharyngeal get to the otic ganglion? |
|
Definition
| Inf. salivatory nucleus-> glossopharangeal-> tympanic nerve ->tympanic plexus (inner surface)->lesser petrosal-> otic |
|
