posterior spinal artery การใช้

ประโยคมือถือ
  • Through the foramen passes the medulla oblongata and its membranes, the accessory nerves, the posterior spinal arteries, and the tectorial membrane and alar ligaments.
  • The anterior and posterior spinal arteries form anastomoses known as the "'vasocorona "'of the spinal cord and these supply nutrients to the canal.
  • The subarachnoid space is filled with cerebrospinal fluid and contains the vessels that supply the spinal cord, namely the anterior spinal artery and the paired posterior spinal arteries, accompanied by corresponding spinal veins.
  • Branches from the posterior spinal arteries form a free anastomosis around the posterior roots of the spinal nerves, and communicate, by means of very tortuous transverse branches, with the vessels of the opposite side.
