Q

Where is the ICA directed? (3)

A
  1. Laterally
  2. Dorsally
  3. Upward in the neck
17
Q

What kind of resistance does the ICA have?

18
Q

Why does the ICA have a low resistance flow pattern?

A

Because it supplies the brain

19
Q

What are the normal variants of the ICA? (2)

A
  1. Coils

2. Kinks

20
Q

How do coils become kinks for the ICA? (2)

A
  1. Aging
  2. High blood pressure
  • this occurs overtime
21
Q

What can kinks lead to?

22
Q

What does the ICA mostly supply in the brain?

A

The anterior circulation of the brain

23
Q

What is the ICA compared to the other branches of the CCA? (2)

A
  1. Larger

2. More lateral

24
Q

What are the 4 portions of the ICA?

A
  1. Cervical portion
    - extra-cranial
  2. Petrous portion
  3. Cavernous portion
  4. Supraclinoid portion
25
Where does the petrous portion pass through?
Passes through this portion of the temporal bone
26
What is the cavernous portion also known as?
Siphon | - tortuous portion where the Ophthalmic artery branches
27
What happens in the supraclinoid portion?
Branching of the intracranial ICA occurs to form the circle of Willis
28
Where does the ICA run compared to the ECA?
Posteriorly
29
When does the cervical portion end?
When the vessel enters the carotid canal through the petrous bone
30
What does it become when the vessel enters the carotid canal through the petrous bone?
Petrous segment
31
What is the first intracranial branch?
Ophthalmic artery
32
What does the ophthalmic artery arise from?
The cavernous segment of the vessel
33
Where does the ICA terminate?
At the anterior cerebral artery
34
Where does the anterior cerebral artery arise from?
The supraclinoid portion of the vessel
35
What does the anterior cerebral artery supply?
The frontal lobes of the brain
