A&P CHAPTER 14: AUTONOMIC NERVOUS SYSTEM Flashcards
AUTONOMIC NERVOUS SYSTEM IS PART OF WHICH NERVOUS SYSTEM
PERIPHERAL
AUTONOMIC NERVOUS SYSTEM IS ALSO KNOWN AS:
INVOLUNTARY SYSTEM
HOW ARE ANS NEURONS DIFFERENT FROM MOTOR NEURONS
THEY ARE MOTOR NEURONS WITH
GANGLIONIC NEURON
PREGANGLIONIC AXON LEAVES CNS TO SYNAPSE WITH SECOND MOTOR NEURON’S POSTGANGLIONIC AXON
WHERE DOES THE PREGANGLIONIC AXON COME FROM
THE CNS
WHERE THE POSTGANGLIONIC AXON EXTEND TO
EFFECTOR ORGAN
DIFFERENCE BETWEEN PRE AND POST-GANGLIONIC AXONS
PRE IS LIGHTLY MYELINATED
POST ARE UNMYELINATED
WHAT IS AUTONOMIC TONE
AUTONOMIC MOTOR NEURONS HAVING A RESTING LEVEL OF SPONTANEOUS ACTIVITY EVEN WITHOUT STIMULI
WHAT ARE AUTONOMIC GANGLIA
MOTOR GANGLIA AND CONTAIN CELL BODIES OF MOTOR NEURONS
IS AUTONOMIC SYSTEM CONDUCTION SLOWER OR FASTER THAN SOMATIC MOTOR SYSTEM
SLOWER
MAJOR NEUROTRANSMITTERS OF THE AUTONOMIC NERVOUS SYSTEM
ACETYLCHOLINE AND NOREPINEPHRINE
HOW IS ACETYLCHOLINE REMOVED FROM A SYNAPSE?
DECOMPOSED BY ACETYLCHOLINESTERASE
HOW IS NOREPINEPHRINE REMOVED FROM A SYNAPSE?
INACTIVATED BY MONOAMINE OXIDASE AND THEN ACTIVE TRANSPORTED BACK TO NERVE ENDINGS
SYMPATHIC FIBERS HAVE ___ PREGANGLIONIC FIBERS AND ____ POSTGANGLIONIC FIBERS
PARASYMPATHETIC FIBERS HAVE ___ PREGANGLIONIC FIBERS AND ____ POSTGANGLIONIC FIBERS
SHORT, LONG
LONG, SHORT
PARASYMPATHETIC IS THE “____”
