1
Q

What is the neurotransmitter used at the cervical ganglion

A

Acetylcholine

2
Q

What is the neurotransmitter between the postganglionic fibre and organ

A

Noradrenaline

3
Q

How many cervical ganglion

A

3

Superior is biggest near base of the skull

4
Q

How do sympathetic nerves form the spinal reach the ganglia in the cervical part of symp chain

A

Exit spinal chord in T1 spinal nerve and travels up symp China to the cervical ganglion

5
Q

How do PARAsymp fibres get form the cns to the organs

A

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

6
Q

What is e neurotransmitters used in the PARAsymp innervation

A

Acetylcholine at synapse and organ

7
Q

What are the 4 PARAsymp ganglia in the head

A

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

8
Q

Where is the ganglion for vagus

A

Within the walls of the organs of chest upper abdomen

9
Q

What do sacral spin,a nerves supply

A

PARAsymp to organs of lower abdomen pelvis and perineum

10
Q

What kind of innervation causes blushing

A

Symp as no PARAsymp to the skin

11
Q

What is the innervation for focussing

A

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
Q

What innervation causes the eye to dilate or construct

A

PARAsymp to constrict the pupil - oculomotor

Symp to dilate - symp nerve fibres

13
Q

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

A

Symp
Ligament tightens
Lens flattens see far away

14
Q

How does the lens contract to see near objects

A

PARAsymp

Ligament relaxes lens fattens to focus on close

15
Q

What are basal tears

A

Tears flowing all the time

16
Q

What are reflex tears

A

Mechanical and chemical stimulation

17
Q

What are the PARAsymp nerves derived from for the lacrimal gland

A

The facial nerve

18
Q

What supply does salivary glands have

A

Secretomotor PARAsymp nerve supply

19
Q

What does the symp supply do to the saliva

A

Sticky due to vasoconstriction

20
Q

What are the major salivary glands that become active at mealtimes

A

Parotid
Submandibular
Sublingual

21
Q

What kind of innervation form what to the parotid gland

A

PARAsymp secretomotor supply to parotid

Cn 9 Glossopharyngeal

22
Q

How do symp nerve fibres get from the cns to the organs of head and neck

A

Cns —> preganglionic fibres to the crucial part of the sympathetic chain ganglion –> postganglionic fibre to the organ
