Answer #1

Answer)True-

Suboccipital muscles are the muscles that are located below the occipital bone .Thre are 4 Suboccipital muscles-

1.Rectus capitis posterior major

2.Rectus capitis posterior minor

3.Obliquus capitis superior

4.Obliquus capitis inferior muscles.

*Rectus Capitis Posterior Minor-Origin: Spinous process of the axis [C2]

*Rectus capitis posterior minor-Origin: Posterior tubercle of atlas [C1]

*.Obliquus capitis superior-Origin: Lateral mass of the atlas bone [C1]

*Obliquus capitis inferior muscles-Origin: Apex of the spinous process of the axis [C2]
