19
Q

Pathway of the Anterior cerebral artery?

A

Runs ventrally following the corpus collosum on external side.
Terminates at the splenium of corpus collosum

20
Q

What is supplied by the superior hypophysial artery

A

Adenohypophysis
Anterior hypothalamus
Infundibulum

21
Q

What is the course of the ICA?

A
  1. Cervical part - No branches
  2. Petrous part - via carotid canal into petrous bone
  3. Cvernous part - goes into thecaverous sinus
  4. Cerebral part - gives the Opthalmic artery and at the optic chiasm it biforcates into middle cerebral arterie
