sub·oc·cip·i·tal tri·an·gle

a deep triangle bounded by the obliquus capitis inferior, the obliquus capitis superior, and the rectus capitis posterior major muscles.

suboccipital triangle

The triangle bounded by the obliquus inferior and superior muscles on two sides and the rectus capitis posterior major muscle on the third side. The floor contains the posterior arch of the atlas bone and the vertebral artery. It is covered by the semispinalis capitis muscle. See also: triangle
