Flashcards in Difficult Autonomimc Lect Deck (22):
1

What is the neurotransmitter used at the cervical ganglion

Acetylcholine

2

What is the neurotransmitter between the postganglionic fibre and organ

Noradrenaline

3

How many cervical ganglion

3
Superior is biggest near base of the skull

4

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

5

How do PARAsymp fibres get form the cns to the organs

Cns --> preganglionic fibres to the ganglion --> postganglionic fibres to the organ

6

What is e neurotransmitters used in the PARAsymp innervation

Acetylcholine at synapse and organ

7

What are the 4 PARAsymp ganglia in the head

Ciliary ganglion - oculomotor
Pterygopalatine - facial
Submandibular - facial
Otic - Glossopharyngeal

8

Where is the ganglion for vagus

Within the walls of the organs of chest upper abdomen

9

What do sacral spin,a nerves supply

PARAsymp to organs of lower abdomen pelvis and perineum

10

What kind of innervation causes blushing

Symp as no PARAsymp to the skin

11

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

12

What innervation causes the eye to dilate or construct

PARAsymp to constrict the pupil - oculomotor
Symp to dilate - symp nerve fibres

13

How does th Ellen's change to focus on far away objects

Symp
Ligament tightens
Lens flattens see far away

14

How does the lens contract to see near objects

PARAsymp
Ligament relaxes lens fattens to focus on close

15

What are basal tears

Tears flowing all the time

16

What are reflex tears

Mechanical and chemical stimulation

17

What are the PARAsymp nerves derived from for the lacrimal gland

The facial nerve

18

What supply does salivary glands have

Secretomotor PARAsymp nerve supply

19

What does the symp supply do to the saliva

Sticky due to vasoconstriction

20

What are the major salivary glands that become active at mealtimes

Parotid
Submandibular
Sublingual

21

What kind of innervation form what to the parotid gland

PARAsymp secretomotor supply to parotid
Cn 9 Glossopharyngeal

22

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
