Document Summary

Origin of fibers: lateral horn in thoracic and lumbar vertebrae (thoracolumbar) Length of fibers: preganglionic - short, postganglionic - long. Location of ganglia: close to the spinal cord: paravertebral or prevertebral ganglion. Origin of fibers: cranium and lateral horn in sacral vertebrae (craniosacral) Length of fibers: preganglionic - long, postganglionic - short. Location of ganglia: near or on target organ. Oculomotor (iii: functions: constricts pupil, eye movement: medial rectus, inferior rectus, inferior oblique, superior rectus. Facial (vii: functions: taste on anterior tongue, facial expression, salivation. Glossopharyngeal (ix: functions: taste on posterior tongue, swallowing, innervation to parotid gland. Vagus (x): accounts for 90% of all parasympathetic preganglionic fibers: movement of pharynx, digestive tract, trachea, heart, taste from epiglottis. T/f: the preganglionic axons of the parasympathetic nervous system are long and the postganglionic axons are short. Length of nerve fibers and location of ganglia. Parasympathetic ganglion in or close to organ.
