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 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 ...

Klumpke's paralysis is a variety of partial palsy of the lower roots of the brachial plexus. [1] [2] The brachial plexus is a network of spinal nerves that originates in the back of the neck, extends through the axilla (armpit), and gives rise to nerves to the upper limb.

The patient would be unable to pull their shoulder back, as when standing at attention. Isolated dorsal scapular nerve injury is uncommon, but case reports usually involve injury to the scalene muscles. [5] The dorsal scapular nerve is typically not anaesthetised during a supraclavicular nerve block. [6] This can cause pain after some surgeries ...
The accessory nerve is tested by evaluating the function of the trapezius and sternocleidomastoid muscles. [8] The trapezius muscle is tested by asking the patient to shrug their shoulders with and without resistance. The sternocleidomastoid muscle is tested by asking the patient to turn their head to the left or right against resistance. [8]
