Introduction[edit | edit source]

Longissimus

The longissimus muscle is not one muscle, but a collection of three separate muscles that run up nearly the entire length of both sides of the spinal column, from the lower back up to the neck. These three muscles include:

  1. Longissimus capitis
  2. Longissimus cervicis
  3. Longissimus thoracis[1]

Longissimus belongs to the intermediate column of the Sacrospinalis group of muscles.[2]

Longissimus Capitis[edit | edit source]

Origin[edit | edit source]

Posterior surface of transverse processes of T1 to T5 and the articular tubercle of C4 to C7.[3]

Insertion[edit | edit source]

Posterior margin of mastoid process and the temporal bone.[3][4]

Nerve Supply[edit | edit source]

Dorsal rami of cervical and thoracic spinal nerves (C6 to T4).[5]

Blood Supply[edit | edit source]

Muscular branches of the occipital artery from the external carotid artery.[5]

Action[edit | edit source]

Acting bilaterally, extends and hyperextends head; acting unilaterally, flexes and rotates the head ipsilaterally.[3]

Trigger Point Referral Pattern[edit | edit source]

Pain is usually referred around the ear, but can also refer nearby into the neck and behind the eye.[6]
