Difficult Autonomimc Lect Flashcards
What is the neurotransmitter used at the cervical ganglion
Acetylcholine
What is the neurotransmitter between the postganglionic fibre and organ
Noradrenaline
How many cervical ganglion
3
Superior is biggest near base of the skull
How do sympathetic nerves form the spinal reach the ganglia in the cervical part of symp chain
Exit spinal chord in T1 spinal nerve and travels up symp China to the cervical ganglion
How do PARAsymp fibres get form the cns to the organs
Cns –> preganglionic fibres to the ganglion –> postganglionic fibres to the organ
What is e neurotransmitters used in the PARAsymp innervation
Acetylcholine at synapse and organ
What are the 4 PARAsymp ganglia in the head
Ciliary ganglion - oculomotor
Pterygopalatine - facial
Submandibular - facial
Otic - Glossopharyngeal
Where is the ganglion for vagus
Within the walls of the organs of chest upper abdomen
What do sacral spin,a nerves supply
PARAsymp to organs of lower abdomen pelvis and perineum
What kind of innervation causes blushing
Symp as no PARAsymp to the skin
What is the innervation for focussing
Symp - for far ways objects get more light in eye as eyes open wider
PARAsymp - for close objects get less light allow orbicularis oculi to work
What innervation causes the eye to dilate or construct
PARAsymp to constrict the pupil - oculomotor
Symp to dilate - symp nerve fibres
How does th Ellen’s change to focus on far away objects
Symp
Ligament tightens
Lens flattens see far away
How does the lens contract to see near objects
PARAsymp
Ligament relaxes lens fattens to focus on close
What are basal tears
Tears flowing all the time
What are reflex tears
Mechanical and chemical stimulation
What are the PARAsymp nerves derived from for the lacrimal gland
The facial nerve
What supply does salivary glands have
Secretomotor PARAsymp nerve supply
What does the symp supply do to the saliva
Sticky due to vasoconstriction
What are the major salivary glands that become active at mealtimes
Parotid
Submandibular
Sublingual
What kind of innervation form what to the parotid gland
PARAsymp secretomotor supply to parotid
Cn 9 Glossopharyngeal
How do symp nerve fibres get from the cns to the organs of head and neck
Cns —> preganglionic fibres to the crucial part of the sympathetic chain ganglion –> postganglionic fibre to the organ
