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
