The middle cerebral artery (MCA) is one of the three major paired arteries that supply blood to the cerebrum.The MCA arises from the internal carotid and continues into the lateral sulcus where it then branches and projects to many parts of the lateral cerebral cortex. More commonly, as the narrowing worsens, pieces of plaque in the internal carotid artery can break free, travel to the brain and block blood vessels that supply blood to the brain. Retropharyngeal internal carotid artery: a rare presentation with significant clinical implications. Unable to process the form. The anatomy of the small segment of the internal carotid artery (ICA) distal to its cavernous segment in the region of the anterior clinoid process, ophthalmic artery, and superior hypophyseal artery has been poorly understood. Fritsch H, Kuehnel W, Fritsch H. Color Atlas of Human Anatomy, Volume 2: Internal Organs. Instant Anatomy. Contents. There may be significant asymmetry between left and right ICA origins: There are several classification systems, the most recent of which was described by Bouthillier et al. The internal carotid artery is located in the inner side of the neck in contrast to the external carotid artery. Toward an endovascular internal carotid artery classification system. Bouthillier et al described (in 1996) a seven segment internal carotid artery (ICA) classification system.
