-
Autonomic nervous system
- innervate cardiac muscle
- smooth muscle
- most exocrine glands and some endocrine glands
- 2 neuron chian
-
postganglionic neurons in the sympathetic division
- an axon may synapse with post ganglionic neurons in the ganglion t first reaches for
- an axon may continue, without, synapsing, through the synaptic trunk ganglion
-
cranial flow
- preganglionic fibers run via:
- Oculomotor nerve (3)
- facial nerve (7)
- glassopharyngeal nerve (9)
- vagus nerve (10)
cell bodies located in cranial nerve nuclei in the brain stem
-
outflow in the vagus nerve
- fibers innervate visceral organs of the thorax and most of the abdomen
- stimulates - digestion reduction in heart rate and blood pressure
- Preganglionic neutrons cell bodieslocated in dorsal motor nucleus in the medulla
