Back muscles Flashcards
Trapezius: Origin?
External occipital protuberance, spinous process of C7-T12
Trapezius: Insertion?
Lateral ⅓ of clavicle, acromion process and spine of scapula
Trapezius: Nerve?
Spinal Accessory nerve C3, C4
Trapezius: Bony Landmarks & Ligaments?
External occipital protuberance, Spine of scapula
Clavicle
Trapezius: Functional Movement?
Scapular elevation
(Shrugging shoulder)
Scapula retraction (pulling shoulders back)
Trapezius: Resisting the muscle?
Stand behind the patient.
Place hands on their shoulders and ask them to shrug their shoulders upwards against your resistance. Apply downwards pressure to resist the upwards movement
Erector Spinae
(Iliocostalis, Longissimus, Spinalis)
I Love Standing (Postural Muscles): Origin?
Spinous processes of vertebrae
Erector Spinae
(Iliocostalis, Longissimus, Spinalis)
I Love Standing (Postural Muscles): Insertion?
Spinous processes and transverse processes of vertebrae above
Erector Spinae
(Iliocostalis, Longissimus, Spinalis)
I Love Standing (Postural Muscles): Nerve?
Dorsal rami of spinal nerves
Erector Spinae
(Iliocostalis, Longissimus, Spinalis)
I Love Standing (Postural Muscles): Bony Landmarks & Ligaments?
Spinous processes and transverse processes
Erector Spinae
(Iliocostalis, Longissimus, Spinalis)
I Love Standing (Postural Muscles): Functional Movement?
Bilateral extension of spine (back arching), unilateral flexion
Erector Spinae
(Iliocostalis, Longissimus, Spinalis)
I Love Standing (Postural Muscles): Resisting the muscle?
Ask the patient to stand upright and lean backwards as far as possible while you place one hand on their lower back.
Apply gentle pressure to resist the backward movement
Latissimus Dorsi: Origin?
Spinous processes of T7 - L5, thoracolumbar fascia, iliac crest, lower 3-4 ribs
Latissimus Dorsi: Insertion?
Intertubercular groove of humerus
Latissimus Dorsi: Nerve?
