ABSTRACT
Obliquus capitis inferior (Fig. 51) • Usual attachments: From the spinous process of C2 to the transverse process of
C1. • Usual innervation: Branch of dorsal ramus of C1 (Raven 1950, Gibbs 1999). Obliquus capitis superior (Fig. 51) • Usual attachments: From the transverse process of C1 to the occipital bone. • Usual innervation: Branch of dorsal ramus of C1 (Raven 1950, Gibbs 1999). Rectus capitis anterior • Usual attachments: From the body of the atlas to the occipital bone. • Usual innervation: Branch of ventral ramus of C1 (Raven 1950, Gibbs 1999). Rectus capitis lateralis • Usual attachments: From the transverse process of the atlas to the occipital
bone. • Usual innervation: Branch of ventral ramus of C1 (Raven 1950, Gibbs 1999). Rectus capitis posterior major (Fig. 51) • Usual attachments: From the spinous process of C2 to the occipital bone. • Usual innervation: Branch of dorsal ramus of C1 (Raven 1950, Gibbs 1999). • Notes: In gorillas this muscle is usually smaller than the rectus capitis posterior
minor, according to the literature review of Gibbs (1999). Rectus capitis posterior minor (Fig. 51) • Usual attachments: From the posterior tubercle of C1 to the region of inferior
nuchal line. • Usual innervation: Branch of dorsal ramus of C1 (Raven 1950, Gibbs 1999). Longus capitis • Usual attachments: From the transverse processes of C2-C6 to the
basiocciput. • Usual innervation: Branches of ventral rami of C1-C5 (Raven 1950, Gibbs
Longus colli • Usual attachments: From the ventral tubercles of C3-C6 and bodies of C2-
C6, to the transverse processes of C2 and C1, ventral tubercle of C1, and the transverse process of C6.
