Autonomic nervous system - Physiology
Cards in this deck (20)
- 1Two autonomic pathways?Sympathetic and Parasympathetic
- 2Autonomic pathways have two neurons which synapse in the autonomic ganglionPreganglionic neuron and Postganglionic neuron
- 3Autonomic nervous system regulates?Cardio
Respiratory
Digestive
Excretory
Reproductive - 4Autonomic pathway is part of which division?efferent
- 5Swelling variscosities occur...?in Postganglionic neuron ends to allow for the release of neurotransmitters into the muscle tissue.
- 6Autonomic pathways are regulated by?Hypothalamus and visceral receptors
- 7Sympathetic nerve fibres leave the spinal cord at .......and........segmental levels.thoracic and lumbar.
- 8Parasympathetic nerve fibres leave the spinal cord at........and..........segmental levels.cranial and sacral.
- 9Sympathetic Pre-ganglionic nerve fibre - ...... Post-ganglionic nerve fibre - .........Short
Long - 10Parasympathetic Pre-ganglionic nerve fibre - ...... Post-ganglionic nerve fibre - .........Long
Short - 11All preganglionic neurons secret....which bind to..... receptors on the .....ganglionic neuron.acetylcholine, nicotinic, post.
- 12At the target organ, the parasympathetic division uses ....................acetylcholine
- 13At the target organ, the sympathetic division uses...........Noradrenaline
- 14In most cases, both divisions operate............antagonistically, i.e. they have opposite actions
- 15Sympathetic ns is generally energy..............expending.
- 16Parasympathetic ns is generally energy...........conserving.
- 17acetylcholine receptor found on the cell body of postganglioinc neurons?Nicotinic receptors
- 18Postganglionic neurons secrete....which binds to.....receptors in the ......pathwaynorepinephrine, adrenergic, sympathetic
- 19Postganglionic receptors secrete.....which bind to..... receptors in the.....pathwayActylcholine, Muscarinic , parasympathetic
- 20Fight or flight response results in.............sympathetic output, coordinated by the...............increased, hypothalamus.
