Description[edit | edit source]
Superior Oblique[edit | edit source]
Inferior Oblique[edit | edit source]
Vertical [edit | edit source]
Origin[edit | edit source]
C3 to T3
Anterior tubercles and anterior surfaces of bodies of C3 to T3
Superior Oblique portion arises from anterior tubercles of the transverse processes of the third, fourth, and fifth cervical vertebræ
Inferior Oblique portion arises from the front of the bodies of the first two or three thoracic vertebræ
Vertical portion arises from the front of the bodies of the upper three thoracic and lower three cervical vertebræ
Insertion[edit | edit source]
Anterior arch of atlas, anterior tubercles of C5-6, anterior surfaces of bodies of vertebrae C2-4
Superior Oblique portion inserts into the tubercle on the anterior arch of the atlas
Inferior Oblique portion into the anterior tubercles of the transverse processes of the fifth and sixth cervical vertebræ
Verticle portion into the front of the bodies of the second, third, and fourth cervical vertebræ.
Nerve Supply[edit | edit source]
C2-6
Ventral rami
Blood Supply[edit | edit source]
Ascending pharyngeal and vertebral arteries
Action[edit | edit source]
Cervical flexion, ipsilateral side flexion and some cervical rotation
Function[edit | edit source]
As well as acting with the other cervical flexors to produce neck flexion, Longus Colli has been shown to have a postural function on cervical curvature, counteracting the lordosis increment related to the weight of the head and to the contraction of the posterior cervical muscles[1].
It is commonly implicated in whiplash[2]
Impaired strength and endurance of the deep neck flexors has been found to be a feature of cervicogenic headache[3].
