Some sources consider the posterior cervical region to be included in the back region.

As discussed in the previous pdf-notes, the back region has the following borders:

• The superior border consists of the external occipital protuberance and the superior nuchal line

• The inferior border consists of the sacro-iliac joints, posterior segments of the ilium bones crests, coccyx

• The lateral border is the posterior median line

  

• There are several so-called suboccipital muscles (mm. suboccipitales) located within the posterior cervical region.

• Rectus capitis posterior minor muscle (m. rectus capitis posterior minor)

• Rectus capitis posterior major muscle (m. rectus capitis posterior major)

  

  Rectus capitis posterior major muscle
  (m. rectus capitis posterior major)

  Origin: spinous process of the C2 vertebra (axis)

  Insertion: lateral part of the inferior nuchal line

  Function: with bilateral contraction, it extends the head, with unilateral contraction, it turns the head ipsilaterally (in its own direction)

  Innervation: occipital nerve, which is a posterior branch of the spinal nerve (C1)

  Blood supply: deep cervical artery

• Obliquus capitis inferior muscle (m. obliquus capitis inferior)

  

  Obliquus capitis inferior muscle
  (m. obliquus capitis inferior)

  Origin: spinous process of the C2 vertebra (axis)

  Insertion: transverse process of the C1 vertebra (atlas)

  Function: with bilateral contraction, it extends the head, with unilateral contraction, it turns the head ipsilaterally (in its own direction)

  Innervation: occipital nerve, which is a posterior branch of the spinal nerve (C1)

  Blood supply: deep cervical artery

• Obliquus capitis superior muscle (m. obliquus capitis superior)
