The autonomic nervous system
| Question | Answer |
|---|---|
| what does ANS SYSTEM mean ? | autonomic nervous system |
| what are the functions of the ANS system ? | controls homeostasis in glands, organs and tissues |
| what are the 2 divisions of the ANS system ? (2) | 1. parasympathetic system 2. sympathetic system |
| what are the functions of the PARASYMPATHETIC system ? (2) | 1. directs housekeeping 2. saves energy |
| what are the functions of the SYMPATHETIC system (2) | 1. mobilizes the body 2. slows down nonessential function |
| PARASYMPATHETIC system can be memorized by .. | " rest and digest " |
| SYMPATHETIC system can be memorized by .. | " fight or flight " |
| what is dual innervation ? | when an organ or tissue is innervated by both parasympathetic and sympathetic systems |
| what types of neurons are in both systems ? (2) | preganglionic neurons ganglionic neurons (postganglionic) |
| where can PREGANGLIONIC neurons be found ? | 1. The brain stem (cranial nerves) 2.The spinal cord (spinal nerves) |
| what do ALL PREGANGLIONIC neurons do ? | Send a synapse of acetylcholine to the nicotinic receptors in the ganglion neuron |
| what do GANGLIONIC neurons do ? | send a synapse of acetylcholine or norepinephrine to the target cell |
| which 2 types of receptors can GANGLIONIC neurons send synapse to ? (2) | 1. adrenergic receptor 2. muscarinic receptor |
| where does PARASYMPATHETIC PREGANGLIONIC neurons originate ? | sacral region of brainstem |
| which nerves does PARASYMPATHETIC PREGANGLIONIC neuron innervate ? (4) | 1. facial nerve 2. vagus nerve 3. oculomotor nerve 3.glossopharyngeal nerve |
| function of facial nerve (1) | 1.controls expression in the face |
| function of the vagus nerve (1) | 1. controls internal organs |
| function of the oculomotor nerve (1) | 1. controls eye movement |
| function of the glossopharyngeal nerve (1) | 1. controls the tongue |
| what is the main characteristic of the PARASYMPATHETIC PREGANGLIONIC neuron ? (1) | -LONG |
| describe how the PARASYMPATHETIC PREGANGLIONIC neuron works.. (2) | - synapse of acetylcholine is sent out to the ganglionic neuron - ganglionic neuron receives acetylcholine through muscarinic receptors |
| where does PARASYMPATHETIC GANGLIONIC (post) neuron originate ? | in peripheral ganglia |
| what is the main characteristic of the PARASYMPATHETIC GANGLIONIC (post) neuron ? | SHORT |
| describe how the PARASYMPATHEITC GANGLIONIC (post) neuron works.. | 1.ganglionic neuron receives acetylcholine through nicotinic receptors 2.ganglionic neuron sends synapse of acetylcholine to target organ 3.target organ accepts acetylcholine (neurotransmitter) through muscarinic receptors |
| where does SYMPATHETIC PREGANGLIONIC neuron originate ? | the spinal cord |
| what is the main characteristic of the SYMPATHETIC PREGANGLIONIC neuron ? | it is SHORT |
| describe how the SYMPATHETIC PREGANGLIONIC neuron works .. | 1. synapse of acetylcholine is sent to ganglionic neuron 2. nicotinic receptors in ganglionic neuron accept acetylcholine |
| what is the main characteristic of the SYMPATHETIC GANGLIONIC neuron ? | it is LONG |
| what are the 3 types of SYMPATHETIC GANGLIONIC neurons ? | 1. chain ganglia 2. collateral ganglia 3. adrenal medullae |
| where does SYMPATHETIC chain ganglia originate ? | sides of the vertebral column |
| what is the function of SYMPATHETIC chain ganglia ?(2) | innervates head and limbs (thoracic cavity) |
| where does SYMPATHETIC collateral ganglia originate ? | front of vertebral column |
| what is the function of SYMPATHETIC collateral ganglia ?(1) | innervates abdomen (pelvic cavity) |
| where does the ADRENAL medullae originate ? | the center of the adrenal gland |
| what is the function of the adrenal medullae ? (1) | release epinephrine in the blood |
| what type of neurotransmitter does parasympathetic and sympathetic preganglionic neurons release ? | Acetylcholine (ACh) |
| in preganglionic neuron, what type of receptor does acetylcholine bind to ? | nicotinic receptor |
| where does ACh bind to nicotinic receptor ? | ganglionic neuron |
| what type of effect is this ? | excitatory effect |
| what type of neurotransmitter does parasympathetic ganglionic neuron release ? | Acetylcholine (ACh) |
| what receptor does ACh bind to ? in parasympathetic ganglionic neuron | muscarinic receptor |
| where does ACh bind to muscarinic receptor ? in parasympathetic ganglionic neuron | in the target cell |
| what 2 effects can this be ? (2) in parasympathetic ganglionic neuron | 1. excitatory effect 2. inhibitory effect |
| what 2 types of neurotransmitters can sympathetic ganglionic neurons bind to ? | 1. norepinephrine NE 2. acetylcholine ACH |
| what receptor does norepinephrine bind to ? in sympathetic ganglionic neurons | adrenergic receptor |
| where does NE bind to adrenergic receptor ? in sympathetic ganglionic neurons | the target cell |
| what receptor does ACh bind to in sympathetic ganglionic neuron ? | muscarinic receptor |
| where does ACh bind to muscarinic receptor ? in sympathetic ganglionic neuron | in target cell |
| what type of effect is ACh binding tp muscarinic reseptor in sympathetic ganglionic neuron ? (2) | 1. excitatory effect 2. inhibitory effect |
| what type of effects are NE binding to adrenergic receptors in sympathetic ganglionic neurons ? (4) | Alpha 1-excitatory effect beta 1-excitatory effect beta 2-inhibitory effect beta 3-excitatory effect |
| what type of hormone is released by the adrenal medullae ? | epinephrine |
| what receptor binds to epinephrine in the sympathetic ganglionic neuron ? | adrenergic receptors |
| what are 3 effects of the parasympathetic system | 1. EYES- eye get smaller 2. DIGESTIVE- increased secretion and defecation 3. RESPIRATORY- bronchoconstriction bronchi gets smaller |
| what are 3 effects of the sympathetic system ? | 1. EYES- eyes get bigger 2. DIGESTIVE- slows down activity 3. RESPIRATORY- bronchodilation bronchi gets bigger |
| compare the parasympathetic and sympathetic systems (3) | they both have total opposite effects parasympathetic (rest and digest) can be local sympathetic (fight or flight) can be widespread |
| what is the tone of the parasympathetic system ? | keeps blood vessels small |
| what is the tone of the sympathetic system ? | slows heart rate down |
