Karten in diesem Stapel (32)
- 1Two parts of the nervous system?Somatic and autonomic nervous system
- 2Somatic nervous system function?Voluntary and reflex control of skeletal muscle.
- 3Autonomic nervous system functions?Reflex control of smooth and cardiac muscle.
Regulation of body's internal environment. - 4Autonomic nervous system operates through?reflex arcs.
- 5Examples of afferent inputsTemperature receptors
Pain receptors
Chemoreceptors
Blood pressure receptors - 6These receptors are found in the ?Heart, blood vessels, lungs, kidneys, gut,bladder
- 7Outputs of the ANS? ......... nerve fibres are autonomic nerve fibres.efferent
- 8Two divisions of the ANS?Sympathetic and parasympathetic nervous systems
- 9Sympathetic nerve fibres leave the spinal cord at .......and........segmental levels. This is the.............................division of the ANS.thoracic and lumbar. Thoracolumbar
- 10Parasympathetic nerve fibres leave the spinal cord at........and..........segmental levels.cranial and sacral.
- 11Both divisions of the ans supply the.....organs.same.
- 12Both divisions also have a .... .................output pathway.two neurone
- 13.............ganglion is a collection of nerve cell bodies in ANS, where synapses between the two neurones occur.Autonomic
- 14Sympathetic Pre-ganglionic nerve fibre - ...... Post-ganglionic nerve fibre - .........Short
Long - 15Parasympathetic Pre-ganglionic nerve fibre - ...... Post-ganglionic nerve fibre - .........Long
Short - 16Both divisions use .............at the synapses in the ganglionacetylcholine
- 17At the target organ, the parasympathetic division uses ....................acetylcholine
- 18At the target organ, the sympathetic division uses...........Noradrenaline
- 19In most cases, both divisions operate............antagonistically, i.e. they have opposite actions
- 20Sympathetic ns .........heart rate. Parasympathetic ns............heart rate.increases
decreases
In a few cases, both divisions work in parallel - 21Adrenal medulla is the .....portion of the ......gland.middle, adrenal
- 22Sympathetic ns is generally energy..............expending.
- 23Parasympathetic ns is generally energy...........conserving.
- 24Parasympathetic ns.........at restdominates
- 25The sympathetic ns becomes...... when energy expenditure is required.active
- 26Neurotransmitters can have ............actions on..............tissues.different
- 272 different noradrenaline receptors?a receptors and b receptors
- 282 types of acetylcholine receptors?Nicotinic receptors
Muscarinic receptors - 29Nicotinic receptors are found in ?autonomic ganglia and at skeletal neuromuscular junction.
- 30Muscarinic receptorsfound at parasympathetic target organs.
- 31Different drugs can block or activate different receptors. ...............is a b blocker. ......................is a muscarinic blocker.Propranolol
Atropine - 32Fight or flight response results in.............sympathetic output, coordinated by the...............increased, hypothalamus.
