MEDC0013 - Autonomic|Quest
ions With Correct Answers|Verified
autonomic nervous system - ✔✔A subdivision of the peripheral nervous system. Controls involuntary
activity of visceral muscles and internal organs and glands.
bodily functions of autonomic nervous system - ✔✔heartbeat
blood pressure
airway resistance
urination
pupillary response
genital erection
digestive motility + secretion
What do the efferent neurones control with regards to the autonomic nervous system? - ✔✔the
sympathetic and parasympathetic response
The sympathetic efferent neurones originate from where? - ✔✔the spinal roots T1-L3
The parasympathetic efferent neurones originate from where? - ✔✔the cranial nerves and spinal roots
S2-S4
sympathetic nervous system - ✔✔fight or flight
parasympathetic nervous system - ✔✔rest and digest
Afferent ANS - ✔✔not divided into para/sympathetic
- autonomic sensory information conducted by general visceral afferent fibres
, autonomic gangion - ✔✔
Where can the cell bodies be found for the pre-ganglionic sympathetic neurones? - ✔✔in the lumbar
and thoracic spinal cord
Where does the pre-ganglionic nerve fibre synapse with the post-ganglionic neurone in the sympathetic
nervous system? - ✔✔either just outside the spinal cord (in the paravertebral chains) or in the midline
(the pre-vertebral ganglia)
Where do the parasympathetic ganglia lie? - ✔✔close to the target sites or in the target organ
What type of response do the parasympathetic post-ganglionic fibres have? - ✔✔a localised response
enteric nervous system - ✔✔a division of the autonomic nervous system consisting of nerve cells
embedded in the lining of the gastrointestinal system
controls secretion and motility within the Gi tract
What triggers the enteric nervous system? what does this control? - ✔✔triggered by food, it controls
the motor functions;
local blood flow, mucosal transport and secretions, and modulates immune and endocrine functions.
What is the efferent neurones main neurotransmitter? - ✔✔acetylcholine
What breaks down acetylcholine? - ✔✔Acetylcholinesterase (AChE)
what synthesises ACh - ✔✔choline acetyltransferase
How is acetylcholine released? - ✔✔calcium dependent exocytosis
