UB ANA 113 Lec 18 B

Autonomic Nervous System

Autonomic Nervous System motor system. Controls cardiac muscle, smooth muscle, glands. 2 Neuron chain.
Where are the centers for the ANS? In PNS and CNS. Hypothalamus, brainstem, spinal cord
Somatic motor skeletal muscle. 1 neuron(motor). Thick heavily myelinated
Visceral motor ANS - glands, smooth, and cardiac muscle. 2 Neuron chain. Pre and post ganglionic. Thin and unmyelinated.
2 Divisions of ANS and differences Sympathetic and parasympathetic. Differ in location of pre+post neuron, neurotransmitter, effect
Sympathetic ... where is the pre neuron T1-L2 = thoracolumbar
Sympathetic... where is the post neuron sympathetic chain or prevertebral ganglia(in front of aorta)
Splanchnic nerve postganglionic neuron of sympathetic synapases with another post ganglionic
sympathetic preganglionic neurotransmitter acetylcholine
sympathetic postganlionic neurotransmitter norepinephrine
Sympathetic general effect flight or fight
Adrenal Medulla on top of kidneys. secretes epinephrine/norepinephrine. Cells derived from post-gang neurons
parasympathetic 1st neuron "craniosacral" - originates along here. Nuclei of cranial nerves 3(eye), 7(lacrimal), 9(salivary), 10(heart/stomach/lungs, Sacral (2,3,4)
parasympathetic post ganglionic on or near the target organ
neurotransmitter of parasympathetic acetylcholine
general effect of parasympathetic rest and digest
heart rate up sympathetic
herat rate down parasympathetic
smooth muscles of bronchioles dialate sympathetic
smooth muscles of bronchioles constrict parasympathetic
urinary bladder relax to fill sympathetic
urinary bladder expel parasympathetic
digestive tract increase movement parasympathetic
digestive tract decrease movement (reduce peristalsis) sympathetic
sweat glands stimulate sympathetic
arrector pili muscles create goosebumps sympathetic
eye dialates (contract muscles of iris) sympathetic
pupil constricts (muscles of iris relax) parasympathetic
vascoconstriction making blood more available for heart and skeletal muscle - associated with sympathetic
