PARASYMPATHETIC DIVISION OF THE AUTONOMIC NERVOUS SYSTEM FOUND
on or close to organ served
IN THE SACRAL REGION, THE PREGANGLIONIC AXONS LEAVE THE VENTRAL
ROOT OF THE SPINAL CORD AND COLLECTIVELY FORM THE __________________
pelvic splanchnic nerve
GIVE ONE AREA THAT THE PREGANGLIONIC NEURONS OF THE SYMPATHETIC
NERVOUS SYSTEM RESIDE
lateral horns of gray matter in T1-L2
WHAT IS ANOTHER DESCRIPTIVE NAME FOR THE SYMPATHETIC DIVISION OF
THE AUTONOMIC NERVOUS SYSTEM?
thoracolumbar
PREGANGLIONIC NEURON AXONS LEAVE THE SPINAL CORD VIA THE VENTRAL
ROOT, ENTER THE SPINAL NERVE THEN PASS THROUGH A SMALL BRANCH
CALLED THE _____________________ TO ENTER THE SYMPATHETIC TRUNK
GANGLION
white ramus communicans
WHAT IS ANOTHER NAME FOR THE SYMPATHETIC TRUNK GANGLION?
paravertebral ganglia
PREGANGLIONIC NEURON AXONS LEAVE THE SPINAL CORD VIA THE VENTRAL
ROOT, ENTER THE SPINAL NERVE THEN PASS THROUGH A SMALL BRANCH
CALLED THE WHITE RAMUS COMMUNICANS TO ENTER THE _________________
sympathetic trunk ganglion
AFTER EXITING THE WHITE RAMUS COMMUNUICANS THE PREGANGLIONIC AXON
HAS TWO COURSES THAT IT MAY TAKE, BOTH OF WHICH WILL THEN SEND THE
AXON THROUGH THE ________________________
gray ramus communicans
A THIRD COURSE FOR THE PREGANGLIONIC AXON DOES NOT TAKE IT THROUGH
THE GRAY RAMUS COMMUNICANS, IT MAY PASS THROUGH THE GANGLION
WITHOUT SYNAPSING AND FORM PART OF THE ______________

GANGLIONIC NEURON IN A _____________ OR ______________ GANGLION (GIVE
EITHER)

WHAT STRUCTURES ARE ONLY SERVED BY THE SYMPATHETIC NERVOUS
SYSTEM AND NOT THE PARASYMPATHETIC?
sweat glands
THE POSTGANGLIONIC FIBERS/ AXONS OF THE PARASYMPATHETIC NERVOUS
SYSTEM ARE CALLED
cholinergic fiber
WHAT NEUROTRANSMITTER DO THE POSTGANGLIONIC AXONS OF THE
SYMPATHETIC NERVOUS SYSTEM RELEASE?
