What is the Origin (2), insertion (2), action and nerve innervation of the SCM?
Which condition effects the SCM during infancy?
Origin
Sternal head: superior part of anterior surface of manubrium
Clavicular head: superior surface of medial third of the clavicle
Insertion
Lateral surface of mastoid process of the temporal bone, Lateral half of superior nuchal line of the occipital bone
Action
Contralateral
Rotation
Ipsilateral
Side Bending
Bilateral
Flexion
Nerve innervation Accessory nerve (CN XI) cervical plexus (C2-C3)
Pathology
torticollis
What is the Origin, insertion, action and nerve innervation of the Trapezius?
Origin Superior nuchal line External occipital protuberance Nuchal ligament Spinous processes of vertebrae C7-T12
Insertion
Lateral one-third of the clavicle
Acromion process
Spine of scapula
Nerve
accessory nerve (motor)
cervical spinal nerves C3 and C4
Action
Rotation
Retraction, elevation, and depression of scapula
Upward rotation of the scapula
What is the Origin, insertion, action and nerve innervation of the Splenius capitis?
Origin
Nuchal ligament and spinous process of C7-T3
Insertion
Mastoid process of temporal and occipital bone
Action

Nerve Innervation
Cervical plexus C3,4
What is the Origin, insertion, action and nerve innervation of the Splenius cervicis?
Origin
Spinous processes of T3-T6
Insertion
Transverse processes of C1-C3
Action
Bilaterally: Extend the head & neck, Unilaterally: Lateral flexion to the same side, Rotation to the same side.
Nerve Innervation

What is the Origin, insertion, action and nerve innervation of the Levator scapulae?
Origin
Posterior tubercles of transverse processes of C1 - C4 vertebrae
Insertion
Superior Angle of the scapula
Action
Elevates scapula and tilts its glenoid cavity inferiorly by downwardly rotating the scapula
