MCA and other arteries coming from circle of Willis arise from the base of the brain (ventral mouse brain). Do they travel along the skull bone, then penetrate the bone and underlying meninges before entering brain parenchyma?
or they migrate along the pia mater and then enter the brain parenchyma?
The middle cerebral artery and anterior cerebral artery are the terminal branch of internal carotid artery.............the internal carotid artery runs vertically upward in the carotid sheath and enters the skull through the carotid canal. I hope this information would help you.
Beska Lawgali The exact anatomy is not clear to me from what you have written. Could you please provide a diagram showing middle cerebral artery penetrating skull and then pia mater?
