Neck Muscles Flashcards
Sternocleido-mastoid: origin?
Sternal head: Manubrium of sternum Clavicular head: Medial third of clavicle
Sternocleido-mastoid: Insertion?
Mastoid process of temporal bone, lateral half of superior nuchal line
Sternocleido-mastoid: Nerve?
Accessory nerve
(CN XI), branches of cervical plexus (C2, C3)
Sternocleido-mastoid: Bony Landmarks & Ligaments?
Mastoid process, clavicle, sternum
Sternocleido-mastoid: Functional Movement?
Bilateral flexion of neck (nodding), unilateral rotation and lateral flexion of neck
Sternocleido-mastoid: Resisting the muscle?
Stand in front of the patient. Place one hand against the side of their head and ask them to turn their head to one side against your resistance. Apply gentle pressure to resist the turning movement.
Splenius Capitis: Origin?
Spinous processes of C7-T3
Splenius Capitis: Insertion?
Mastoid process of temporal bone, lateral third of superior nuchal line
Splenius Capitis: Nerve?
Dorsal rami of spinal nerves
Splenius Capitis: bony Landmarks & Ligaments?
Spinous processes, mastoid process
Splenius Capitis: Functional Movement?
Unilateral extension, rotation, and lateral flexion of neck
Splenius Capitis: Resisting the muscle?
Stand beside the patient. Place one hand on the side of their head and ask them to tilt their head to one side against your resistance. Apply gentle pressure to resist the tilting movement.
