41
Q

What are the 5 layers of the scalp?

A

S - skin

C - dense connective tissue

A - aponeurosis of occipitofrontal muscle

L - loose alveolar connective tissue

P - periosteum

42
Q

On a wet specimen what layers of the scalp are not easily visable?

A

the 4th and 5th layers

43
Q

What is the innervation of the scalp?

A

in the anterior part of the scalp the nerve supply is by all three branches of the trigeminal nerve

in the posterior half of the scalp nerve supply is from cutaneous branches of cervical spinal nerves C2 and C3

44
Q

What structure forms from the ventral rami of C5 to T1 and what does this formation innervate?

A

brachial plexus

upper limbs

45
Q

the scalp is richly supplies by blood vessels

in which layer of the scalp are blood vessels present?

A

connective tissue layer

46
Q

Would wounds of the scalp bleed profusley or sparingly?

A

profusley

connective tissue layer prevents vasoconstriction

47
Q

supratrochlear and supra-orbital arteries are branches of what larger artery?

A

ICA

48
Q

superficial temporal, posterior auricular and occipital arteries are branches of what larger artery?

A

ECA

49
Q

Blood vessels of the scalp are mostly from what?

A

ECA

50
Q

DO the blood vessels anastomise on the scalp?

A

yes

51
Q

a

A

superificial temporal vein

52
Q

b

A

posterior auricular vein

53
Q

c

A

external jugular vein

54
Q

d

A

right subclavian vein

55
Q

e

A

supra-orbital vein

56
Q

f

A

supratrochlear vein

57
Q

g

A

facial vein

58
Q

h

A

anterior jugular vein

59
Q

i

A

internal jugular vein

60
Q

What are valveless veins called that run form the outside to inside of the skull bones?

A

emissary veins

61
Q

What is diploe?

A

spongy cancellous bone separating the inner and outer layers of cortical bone of the skull

62
Q

What potentil grave complication could arise form scalp infections due to the presence of emissary veins?

A

can spread infection intracranially

63
Q

Are there lymph node sin the scalp?

A

no

lymph drains away from scalp into lymph nodes of the head and neck

64
Q

Where do the msucles of facial expression lie?

A

within the superficial fascia of the face

65
Q

how do these differ in terms of position compared to other skeletal msucles? and in terms of attachment?

they are more superficial

they are connected to the skin

has a duct

80
Q

Which nerve branches can you see emerging form the anterior border of the parotid gland?

A

facial nerve

81
Q

What muscle does the parotid gland pierce in order to open into the oral cavity?

A

buccinator

82
Q

opposite the decond upper molar tooth

83
Q

What are structure that enter/leave the parotid gland?

A

facial nerve

ECA

retromandibular vein

84
Q

What division of the autonomic nervous system is the secretomotor of the parotid gland?

A

parasympathetic and sympathetic

parasympathetic

85
Q

What cranial nerve carries parasympathetic fibres destined for the parotid gland?

A

IX

glossopharyngeal nerve

86
