What is an internal carotid artery?
Inner carotid artery is a blood vessel that gives oxygenated blood from the heart to the brain. A pair container with one on both sides of the head is a branch of a larger common carotid artery, the other branch is the outer carotid artery, which adds blood to different structures in the face, head and neck. The inner carotid artery is formed from a conventional carotid in the throat at approximately the height of the upper limit of Adam's apple. After the head penetrates, it branches into several smaller arteries, among them eye artery, front choroidal artery, front cerebral artery, medium cerebral artery and rear artery. The largest blood vessel in the body, aorta rises from the heart and curve at the top of the chest to form an aortic arch. Here's a place where the left and right of the common carotid arteries come from, although the right common branches of carotids are not directly outside the aort, but outside the brachiocephalic artery. Each side of the ordinary carotids will perform on its appropriate side of the neck and at the height of the fourth cervical defense each bifur into the outer and interiorThe carotid arteries, with the outer carotid of the most fierce couple, which means it lies closer to the skin.
Unlike the outer carotid, which forms more branches in the throat immediately after deviation from the normal carotid, the inner cervical artery continues up the neck and enters the head behind the angle of the jaw, just deep to the ear, like an undivided inflow. This ship can be classified into seven unique segments, some segments branching into other vessels and others are not known at all. For example, part of the throat is a cervical segment, also known as C1, although no branches are found.
After entering the head, Petrous segment of the inner cervical artery or C2 begins. It is named for its location inside Petrous part of the temporal bone, the pyramid part of the temporal bone in the skull, with which the entrance to the ear canal is located. Several tiny branches of the inner carotid are foundIn C2, including caroticotototympanic and Vidian arteries of the ear.
Above the petors segment is a lacer segment, C3, which does not create any branches and cavernous segment, C4, which make up many small tributaries. C4, which is located in cavernous sinuses, a grid of small blood vessels, causes meningohypophysal and inferolateral tribes. These smaller containers give such structures as the dura mater around the brain and pituitary.
The last three segments are C5, C6 and C7 or Clinoid, Ophthalmic and communication parts of the internal carotic artery. While the clinoid segment has no other branches, the eye and communication segments lead to the main branch of the inner carotid: ophthalmic and excellent hypophysal artery in the ophthalmic segment; and rear communication, front choroidal, front brain and medium brain arteries in the communication segment. The latter two arteries are terminal branches penetrating into the brain, which means that the inner carotid artery ends where it branches into the front and medium brainCH arteries.
