Chapter 15 Autonomic Nervous System
Key structures of the Autonomic Nervous System.
Terms in this set (52)
autonomic nervous system
= visceral motor effectors of smooth muscle, cardiac muscle, and glands.
controls vital bodily functions w/o consciousness.
cell body located in spinal cord or brain
cell body located in autonomic ganglion; synapses with target cells / organ
visceral reflex arc
visceral sensory to CNS to visceral motor to organs.
ANS is motor portion of visceral reflex arc
sympathetic division of ANS
also called the Thoraco-Lumbar division.
from T1 to L2.
"fight or flight" = emergency, excitement, exercise.
Parasympathetic division of ANS
also called craniosacral division (composed of cranial and sacral nerves).
for normal maintenance, i.e., "Rest and digest" = refueling, removal.
response of sympathetic
response of parasympathetic
branching of sympathetic
branching of parasympathetic
postganglionic axons of sympathetic
long in length
postganglionic axons of parasympathetic
short in length
ganglion of sympathetic
ganglion of parasympathetic
on effector organ
cell bodies of sympathetic
lateral horn T1-L2
cell bodies of parasympathetic
brain steam and sacral spinal cord
neurotransmitter of sympathetic
neurotransmitter of parasympathetic
cranial outflow of parasympathetic
cranial nerves 3, 7, 9, 10.
these cranial nerves originate in the dorsal motor nucleus of the medulla.
CN III - oculomotor nerve
pupil constriction for iris.
controlled focus for ciliary muscle.
CN VII - facial nerve
tears are produced by lacrimal gland.
saliva is produced by submandibular gland and sublingual gland.
CN IX - glossopharyngeal nerve
saliva is produced by parotid gland.
CN X - vagus nerve
to all organs of the thorax, abdomen, and first half of large intestine.
S2 - S4 spinal nerves, which are also called pelvic splanchnic nerves.
connects to second 1/2 of large intestine, rectum, urinary bladder, ureters, and reproductive organs.
sympathetic trunk (chain) ganglia
meeting place of pre- and post-ganglionic axons.
located next to vertebral column.
white ramus communicans
lateral and have myelin.
goes to ganglion and contains pre-ganglionic axon
gray ramus communicans
medial and without myelin.
comes from ganglion and contains post-ganglionic axon
direction of impulse
lateral horn to ventral root to spinal nerve to ramus communicans to ganglions
superior cervical ganglion
connects to head
middle cervical ganglion
connects to salivary glands and heart
inferior cervical ganglion
also called stellate ganglion.
connects to heart
connects to abdomen
an extension of the sympathetic division.
inner part of the adrenal gland located on top of the kidney.
made of postganglionic sympathetic cells.
main cells of the adrenal medulla.
secrete norepinephrine and epinephrine.
main integration center of ANS function
hypothalamus is affected by...
limbic system: emotions and cerebral cortex - frontal lobe: thoughts
heart rate: Sympathetic
respiratory rate: Sympathetic
blood vessels to muscles: Sympathetic
blood vessels to skin: Sympathetic
adrenal medulla: Sympathetic
increases production of epinephrine
digestive functions: Sympathetic
urinary bladder: Sympathetic
heart rate: parasympathetic
respiratory rate: parasympathetic
blood vessels to muscles, blood vessels to skin and the adrenal medulla: parasympathetic
no parasympathetic control
digestive functions: parasympathetic
urinary bladder: parasympathetic
