Noun: * Scalene muscle: Any of the four pairs of muscles (anterior, middle, posterior, and smallest) located on each side of the neck, extending from the cervical vertebrae to the first or second rib. These muscles are involved in the lateral flexion and rotation of the neck and assist in the process of respiration, particularly during forced inhalation by elevating the ribs.
