Chp 14 - SNS & ANS

Answer
SNS or ANS? sensory neurons get input from special and somatic senses SNS
SNS or ANS? motor neurons - skeletal muscle SNS
SNS or ANS? movement is consciuosly perceived/controlled SNS
SNS or ANS? accurate and rapid excitation of skeletal muscle SNS
SNS or ANS? monosynaptic SNS
SNS or ANS? ACh only SNS
SNS or ANS? snesory neurons have chemorecptors and mechanoreceptors ANS
SNS or ANS? motor neurons excite or inhibit smooth muscle, cardiac muscle or glands ANS
SNS or ANS? movement is involuntary ANS
SNS or ANS? widespread and relatively slow action on smooth, cardiac and glands ANS
SNS or ANS? disynaptic (pre and postganglionic) ANS
SNS or ANS? ACh or norepinephrine (NE) ANS
SNS or ANS? output is sympathetic or parasympathetic ANS
The ANS is divided into two divisions called sympathetic and parasympathetic
Division of the ANS that is primarily concerned with the elevation of metabolic rate and increased alertness sympathetic
Division of the ANS that is generally responsible for activities that conserve energy and lower thh metabolic rate parasympathetic
Division of the ANS that is found in the cell bodies in gray matter in all thoracic vertebra and Lumbar vertebra 1 and 2 sympathetic
What is the sympathetic division of the ANS stimuluated by adrenal medulla
division of the ANS that is associated with vigorous physical acitivity and production of ATP sympathetic
Division of the ANS that is responsible for Emotions such as fear, embarrasment or rage sympathetic
division of the ANS that is responsible fo the "Fight-or-Flight" response sympathetic
Division of the ANS that is 80% epinephrine and 20% norepinephrine/dopamine sympathetic
Division of the ANS responsible for SLUDD - salivation, lacrimation, urination, digestion, defacation parasympathetic
Division of the ANS that is responsible for resting and digesting parasympathetic
Division of the ANS found in cell bodies in 4 cranial nerves and 2nd-4th sacral segments parasympathetic
Division of the ANS that has receptors for ACh both sympathetic and parasympathetic
AKA thorcolumbar sympathetic ANS
AKA craniosacral parasympathetic
What does is mean that the ANS has dual innervation most of the viscera receive both parasympathetic and sympathetic input - may have antagonist effect or complementary effect
some structures such as the adrenal medulla, arrector pili, sweat glands and blood vessels, get only ______________ fibers of the ANS sympatheic - no dual innervation
axons of both sympathetic and parasympathetic neurons of the thorax, abdomen and pelvis form the ________________ plexus autonomic
Major cardiac and pulmonary plexus in found in the ___________ plexus thorax
major celiac plexus innervates what organs pancreas, spleen, gall bladder and stomach
major superior mesenteric plexus innervates what organ upper intestines
major inerfior mesenteric plexus innervates what organ lower intestines
major hypogastric plexus innervates what organs bladder, ureters, reproductive organs
major renal plexus innervates what organs kidneys
In ANS, how many motor neurons are involved in a reflex arc? 2
In SNS, how many motor neurons are involved in a reflex arc? 1
What is the effector of an automic reflect arc? smooth and cardiac muscles; glands
The two types of receptors in the ANS are cholinergic receptor and adrenergic receptors
What neurotransmitter do cholinergic receptors accept? ACh
What are the two types of cholinergic receptors? nicotinic and muscarinic receptors
Are nicotinic receptors excitatory or inhibitory or both always exctitatory
Are muscarinic receptors excitatory or inhibitory or both? both depending on the area
Where are nicotinic recptors found? all ANS postganglionic neurons and skeletal muscle
Where are muscarinic receptors found? on all glands, smooth and cardiac muscles
What neurotranmitter binds to adrenergic receptors? norepinephrine/epinephrine
What are the two types of adrenergic receptors? alpha and beta receptors
Are adrenergic receptors exitatory, inhibitory or both both, depending on the location
where are the adrenal glands found? on superior side of each kidney
what do the adrenal glands secrete? steroid hormone and neurotransmitter hormone
What ANS system do the adrenal glands innervate sympathetic ANS
How do the adrenal glands create a longer lasting effect of the sympatheic ANS? by secreting directly into the blood and not onto other neurons
ANS is regulated by what three levels of the CNS? cerebral cortex, hypothalamus, spinal cord
The cerebral cortex is influences by our emotions
Where does the fight or flight response originate? hypothalamus
