Segments of vertebral artery anterior projection. The vertebral artery may be divided into four parts: The first (preforaminal) part runs upward and backward between the anterior scalene and the longus colli muscles. In front of it are the internal jugular and vertebral veins, and is crossed by the inferior thyroid artery; the left vertebral is ...
In fact, acute sulcal artery syndrome should be suspected in patients with acute hemicord syndrome, and vertebral artery dissection should be suspected in cases of high cervical cord involvement. In a recent review by Tan YJ, et al. in 2021, good functional recovery was seen in most, and vertebral artery dissection was the leading cause of ...
The brachiocephalic artery or trunk is the first and largest artery that branches to form the right common carotid artery and the right subclavian artery. This artery provides blood to the right upper chest, right arm, neck, and head, through a branch called right vertebral artery .
The anterior cerebral artery forms the anterolateral portion of the circle of Willis, while the middle cerebral artery does not contribute to the circle. The right and left posterior cerebral arteries arise from the basilar artery , which is formed by the left and right vertebral arteries .
In the deep groove on the upper surface of the posterior arch of the atlas are the vertebral artery and the first cervical or suboccipital nerve. In the past, the vertebral artery was accessed here in order to conduct angiography of the circle of Willis. Presently, formal angiography of the circle of Willis is performed via catheter angiography ...
The longus colli is situated on the anterior surface of the vertebral column, between the atlas and the third thoracic vertebra. It is broad in the middle, narrow and pointed at either end, and consists of three portions, a superior oblique, an inferior oblique, and a vertical.
Anatomically, the human neck is divided into four compartments: vertebral, visceral, and two vascular compartments. [1] Within these compartments, the neck houses the cervical vertebrae, the cervical portion of the spinal cord, upper parts of the respiratory and digestive tracts, endocrine glands, nerves, arteries and veins. The muscles ...
