ANS Flashcards
What does GVA monitor
- stretch
-pain
-temperature and chemical changes - nausea and hunger
What two systems lie in the GVE category and where do they synapse?
-Sympathetic and parasympathetic
- peripheral ganglion
Somatic nervous system is responsible for innervation of?
Skeletal muscle
How many motor units does the ANS and Somatic have
2 ANS
1 Somatic
Where does the postganglionic go to ?
Effector organ
Where does the parasympathetic come from
Craniosacral division
Where does the sympathetic come from
Thoracolumbar division
Where does the cranial division arise from?
- nuclei in the brainstorm
what four cranial nerves are associated with the cranial division
-cn 3: ocuulomotor
- cn 7: Facial
- cn 9: glassopharyngeal
- cn 10: vagus
What levels do the sacral division arise from
Where do the cell bodies lie
S2, S3, S4
Lateral horns of the gray matter
Cranial nerve 3
Where do preganglionic axons travel to
What does the postganglionic axons innervate
-Oculomotor
- Ciliary ganglion of the orbit
- pupillary contractor muscle and the ciliary body of the lens
Cranial nerve 7
Preganglionic axon travel to the?
Postganglionic axons innervate
- facial nerve
- pterygopalatine ganglion and submandibular ganglion
- 2/3 main salivary glands, lacrimal glands and mucous glands of the nasal and oral cavities
Cranial 9
Preganglionic axon travels to the
Postganglionic axons innervate the
-glassopharyngeal
- Otic ganglion
- parotid salivary gland
Cranial nerve 10
Preganglionic axon synapses with? And in the?
Postganglionic axons innervate the
- vagus
- postganglionic cell bodies : in the intramural ganglia
- with or within the target organ
- the thoracic organs and organs of the foregut and midgut
Sacral division
Preganglionic axons leave ? And travel to ? By what nerves?
What do they synapse with?
- S2-S4: target organs : splanchic nerves
- postganglionic cell bodies that reside in intramural ganglion
