Q

Why can untreated septal haematoma lead to saddle nose deformity?

A

Because the septal cartilage is avascular, it receives its oxygen and nutrient supply from the overlying perichondrium. A septal haematoma is an accumulation of blood between the cartilage and perichondrium. This leads to avascular necrosis of the cartilage - leading to the deformity.

28
Q

Why does pathology of the parotid gland affect the face?

The facial nerve and its branches pass through the substance of the parotid glandPathology of the parotid may therefore affect facial nerveThis would cause weakness/paralysis of all/some of muscles of facial expression on ipsilateral side

Q

Briefly outline the mechanism behind the corneal reflex.

A

Corneal reflex - blinking of eyelid in response to tactile, thermal or painful stimulation of cornea.Ophthalmic nerve (division of trigeminal) detects stimulus.Facial nerve causes contraction of the orbicularis oculi muscleIf this reflex absent, damage to either likely

36

A

Trigeminal (again!)Mucous membranes and floor of oral cavityExternal earLower lipChinAnterior 2/3 of tongue (only general sensation - taste is by chorda tympani, a branch of facial nerve)Lower molar, incisor and canine teeth and associated gingivaThat was all sensory

39
Q

What is the motor supply of mandibular nerve?

A

Muscles of masticationMedial pterygoid, lateral pterygoid Masseter TemporalisAnterior belly of digastric and mylohyoid musclesTensor veli palatiniTensor tympani Also parasym to salivary glands…

40
Q

What nerve do dentists block when doing a root canal on lower teeth?

A

Inferior alveolar nerveLingual nerve not targeted, but anasthesia can sometimes spread to it causing numbness of the anterior 2/3 of tongue

41
Q

Increase income equality
Increases socio-evaluative threat
Increases stress
Decreases health

52
Q

Why are people in deprived areas more ill?

A
  • Tendency to manage health as a series of crises
  • Normalisation of ill-health
  • Difficulty marshalling the resources needed for negotiation and engagement with health services
  • Less prevention,more fix
53

Cultures
Genetic makeup

Risks, exposures, protective factors
Responses and recognition
Healthcare quality and quantity

54
Q

Innervation of salivary glands?

A

Above oral fissure - Greater Petrosal

Below oral fissure - Chorda tympani

55
Q

Neural control of swallowing and gag reflex

A

Mechanoreceptors -> glossopharyngeal nerve -> medulla -> vagus nerve -> pharyngael constrictors

In gag reflex, same thing but uncoordinated because tongue didn’t set it off

56
Q

Components of saliva

A 
Mucins for lubrications
Salivary amylase
Lingual lipase
IgA, lysozyme, lactoferrin
K+
HCO3-
57
Q

Which gland produces most volume of saliva?

A

Submandibular

58
Q

There is hormonal control of saliva production. True/false.

A

False.

Under autonomic control - mainly parasympathetic

59
Q

Which nerve stimulates parotid, submandibular and sublingual?

A

Parotid - glossopharyngael

Branch of facial nerve - the others

60
Q

Briefly describe saliva production?

A

Acinus lined by acinar cells
Produce initial saliva which is isotonic
Ductal cells modify and make hypotonic
Myoepithelial cells contract to eject saliva

Kallikrein increases blood flow to salivary gland

61
Q

How do ductal cells modify saliva?

A

Take Na+ and Cl-

Give K+ and HCO3-

Overall make saliva hypotonic

62
Q

What happens to saliva at high flow rates?

A

Less contact time with ductal cells
Hence more Na+ and Cl-, less K+ would be like isotonic

HOWEVER, more HCO3- because secretion increased at high flow rate

63
Q

Why are the cervical vertebrae more prone to horizontal displacement?

Why does slight dislocation not cause any problems?

A

Cos their articular facets are more horizontal allowing easy slipping

Because vertebral foreamen is quite big, so spinal chord not compressed

64
Q

Pharynx - which is where?

A

Nasal - superior to soft palate

Oral - between soft palate and larynx

Laryngo - posterior to larynx
