The posterior scalene, (Latin: scalenus posterior) is the smallest and most deeply seated of the scalene muscles. It arises, by two or three separate tendons, from the posterior tubercles of the transverse processes of the lower two or three cervical vertebrae, and is inserted by a thin tendon into the outer surface of the second rib, behind ...
The prevertebral fascia is prolonged downward and laterally behind the carotid vessels and in front of the scalene muscles. It forms a sheath for the brachial nerves , subclavian artery , and subclavian vein in the posterior triangle of the neck; it is continued under the clavicle as the axillary sheath and is attached to the deep surface of ...
The erector spinae (/ ɪ ˈ r ɛ k t ər ˈ s p aɪ n i / irr-EK-tər SPY-nee) [1] or spinal erectors is a set of muscles that straighten and rotate the back.The spinal erectors work together with the glutes (gluteus maximus, gluteus medius and gluteus minimus) to maintain stable posture standing or sitting.
Posterior triangle is bordered by the posterior border of the sternocleidomastoid muscle, anterior border of the trapezius muscle and the superior edge of the middle third of the clavicle. This triangle contains the sternocleidomastoid, trapezius, splenius capitis, levator scapulae, omohyoid, anterior, middle and posterior scalene muscles. [1 ...
Muscle [3] Visual reference Method of activation 1: Anterior and middle scalenes: Look straight ahead and lift head anterior 2: Posterior scalenes: Turn head 30 degrees away and lift anterior 3-5: Pectoralis minor: Push ipsilateral elbow towards opposite ASIS. 6-8: Serratus Anterior: Push arm anteriorly 9-11: Latissimus dorsi
The deep cervical fascia (or fascia colli in older texts) lies under cover of the platysma, and invests the muscles of the neck; it also forms sheaths for the carotid vessels, and for the structures situated in front of the vertebral column. Its attachment to the hyoid bone prevents the formation of a dewlap. [1]
The suprascapular artery and transverse cervical artery both head laterally and cross in front of (anterior to) the anterior scalene muscle and the phrenic nerve. The inferior thyroid artery runs superiorly from the thyrocervical trunk to the inferior portion of the thyroid gland. There is significant variation in the origin of these vessels.
