The scalene muscles are a group of three paired muscles that are located in the lateral compartment of the neck. Originating from the anterior or posterior tubercles of the cervical vertebrae, these muscles insert into anatomical features of the first or second ribs. On each side of the neck, you’ll find the following scalene muscles: anterior scalene, middle scalene, and posterior scalene. Animation @anatomy.app #osteopathy #anatomy | Bradley Blair Osteopath
