there are _____ sympathetic collateral ganglia located in the abdominal cavity
3
specialized second-order neurons of the sympathetic nervous system that release neurotransmitters into the bloodstream are located in the
adrenal glands
vagus nerve
almost 75% of all parasympathetic outflow travels along the
a decrease in the autonomic tone of the smooth muscle in blood vessels would result in
an increase in vessel diameter
second-order (postganglionic) neurons of the autonomic nervous system are located in
autonomic ganglia
normal control of the diameter of the respiratory passages depends upon
both parasympathetic and sympathetic levels of stimulation
preganglionic fibers of the sympathetic nervous system that carry motor impulses to targets in the body wall or thoracic cavity synapse in a
chain ganglion
chain ganglia
groups of second-order sympathetic neurons lying along either side if the spinal cord
collateral ganglia
groups os second-order neuroons that innervate organs in the abdominopelvic region
increased parasympathetic stimulation
increases gastric motility
preganglionic neurons of the sympathetic nervous system are located in the
lateral gray horns of segments T1 to L2 of the spinal cord
autonomic nerves
nerves that innervate organs in the ventral body cavities are
Norepinephrine
neurons of the sympathetic branch of the autonomic nervous system release the neurotransmitter _____ at their effectors
postganglionic neurons in the adrenal gland
release epinephrine into blood capillaries
the celiac ganglion innervates the
stomach, liver and pancreas
inferior mesenteric ganglion
sympathetic innervation of the urinary bladder and sex organs is by way of the
Alpha waves
the brain waves produced by normal adults while resting with their eyes closed
delta waves
the brain waves that are characteristic of newborn infants are
theta waves
the brain waves that are characterstic of children and frustrated adults are
parasympathetic division
the disision of the autonomic nervous system that maintains homeostasis during resting conditions
postganglionic axons of autonomic neurons are usually
unmyelinated
