Origin of sternocleidomastoid:
Sternal head: superior part of anterior surface of manubrium sterni
Clavicular head: superior surface of medial third of the clavicle
Insertion of sternocleidomastoid:
Lateral surface of mastoid process of the temporal bone
Lateral half of superior nuchal line of the occipital bone
3 aspects of the trapezius:
Upper fibres
Middle fibres
Lower fibres
Origin of upper fibres:
Medial third of the superior nuchal line
Eternal occipital protuberance
Insertion of upper fibres:
Lateral third of clavicle
Origin of middle fibres:
Nuchal ligament attached to the spinous processes of C1-C6 vertebrae
Spinous processes
Supraspinous ligaments of vertebrae
Insertion of middle fibres:
Medial acromial margin
Superior crest of spine of scapula
Origin of lower fibres:
Spinous processes and supraspinous ligaments of vertebrae T4-T12
Insertion of lower fibres:
Lateral apex of the medial end of scapular spine
Origin of levator scapulae:
Transverse processes of vertebrae C1-C4
Insertion of levator scapulae:
Medial border of scapula (from superior angle to root of spine of scapula)
3 aspects of scalene:

Scalenus medius
Scalenus posterior
Origin of scalenus anterior:
Anterior tubercle of transverse processes of vertebrae C3-C6
Insertion of scalenus anterior:
Anterior scalene tubercle of rib 1
