Q

Why do lacerations to the scalp bleed profusely and how is this fixed?

A

The dense connective tissue layer is unable to retract to its original position

-Blood vessels remain open

All layers must be closed during suturing

Which main arteries provide blood supply to the brain?

A
  • Internal carotid artery
  • Vertebral artery
28
Q

What arteries form the cerebral arterial circle/circle of willis?

A

Formed by an anastomosis between:

  • 2 Internal Carotid arteries (ICA)
  • 2 Vertebral arteries
29
Q

Vertebral arteries enter at the _________where they unite to form the _________.

A

Vertebral arteries enter at the foramen magnum where they unite to form the basilar artery.

30
Q

Complete the diagram of the blood supply to the brain

A
31
Q

Common carotid lies deep to _______________

A

Common carotid lies deep to sternocleidomastoid

32
Q

Internal carotid supplies the ______

External carotid supplies the _______

A

Internal carotid supplies the brain

External carotid supplies the face

33
Q

Label the diagram on blood supply to the brain

A
34
Q

What does the cerebral arterial circle allow for?

A

These anastomoses allow for collateral circulation

35
Q

What arteries does the cerebral arterial circle give rise too?

A

Gives rise to the cerebral arteries

  • Anterior
  • Middle
  • Posterior
36
Q

label the blood vessels from the cerebral arterial circle

A
37
Q

What does the anterior cerebral artery supply?

A

-supplies the medial and superior surfaces of the brain and frontal pole.

38
Q

What does the middle cerebral artery supply?

A

-the lateral surfaces and temporal pole.

39
Q

What does the inferior cerebral artery supply?

A

-the inferior surfaces and occipital pole.

40
Q

Label the cerebral arteries

A
41
Q

What causes a stroke?

A

Strokes are caused by an embolism in a cerebral artery.

42
Q

How do strokes cause a neurlogical defecit?

A

No anastomoses of cerebral arteries once within the brain

  • No way to avoid ischaemia
  • Hence neurological deficit

The vessel, and so the area of the brain supplied by the vessel, will affect what these deficits will be

43
Q

What does this show?

A

ischaemia caused by stroke

44
Q

What does this show?

A

Ischaemia caused by stroke

45
Q

What portion of the brain does this artery supply?

A.Anterior

B.Inferior

C.Lateral

D.Posterior

Rostral

A

C.Lateral
