C2-C6

The musculus longus capitis , also called musculus capitis colli (from Latin musculus "muscle", longus "long"; caput "head" and collum "neck"; "long head muscle") is a striated muscle ( skeletal muscle ), which is between the sixth Cervical vertebrae and occiput runs prevertebrally (located in front of the spine). The thickness of the muscle increases from bottom to top and while it has only one attachment point on the head, it has several origins, namely the anterior tubecula of the transverse processes of the cervical vertebrae 3 to 6.

The blood supply is provided by the ascending cervical artery , vertebral artery and ascending pharyngeal artery .

function

The longus capitis muscle, which is isolated on one side , causes lateral flexion and slight rotation (turning) of the head to the same side (towards the working muscle) when it contracts ; in cooperation the two muscles lead to a ventral flexion of the head (forward bending) .
