Why are my scalenes so tight?
Ideally, scalene muscles are meant to be relaxed and off duty. They are non-postural and fast-twitching muscles (meaning they fatigue quickly). When scalene muscles are overburdened, muscle fibers tighten and accrue waste products to cause neck stiffness, soreness, and limited range of motion.

Where are the scalene muscles located?
Log In. The scalene muscles are three paired muscles (anterior, middle and posterior), located in the lateral aspect of the neck. Collectively, they form part of the floor of the posterior triangle of the neck. The scalenes act as accessory muscles of respiration, and perform flexion at the neck. In this article, we shall look at the anatomy ...
Where is the anterior scalene located?
Anterior Scalene. The anterior scalene muscle lies on the lateral aspect of the neck, deep to the prominent sternocleidomastoid muscle. Attachments: Originates from the anterior tubercles of the transverse processes of C3-C6, and attaches onto the scalene tubercle, on the inner border of the first rib.
What is the innervation of the C6-C8?
Innervation: Anterior rami of C6-C8. Anatomical Relationships. The scalene muscles are an important part of the anatomy of the neck, with several important structures located between and around them. The brachial plexus and subclavian artery pass between the anterior and middle scalene muscles.
