The cerebral cortex is the largest part of the brain and plays a key role in awareness, communication, consciousness and memory.

Epinephrine or adrenalin activates arousal mechanisms which are triggers for the fight-or-flight response and posturing. Physical queues of attack posturing are elevated shoulders, clenched jaw and fists, flexed arms and aggressive behavior.

Skeletal muscle contraction occurs when an action potential from the brain reaches the neuromuscular junction. It causes a calcium ion influx which starts the process of a muscle contraction.

Scalene muscles are typically reposed during normal respiration and only come into action during heavy exertion or forced inhalation. However, in a faulty breathing pattern, the scalene (along with the upper trapezius, levator scapulae, SCMS and pec minor) become primary breathing muscles and are active with each inspiration. This additional stress leads to the development of trigger points within these muscles. Assisting the client to correct their breathing pattern is as essential to rehabilitation as is releasing the hypertonic muscles.
