@atomedgeanatomy: The pectoralis major is made up of three main parts: The clavicular and sternocostal heads, and abdominal part. Each region contributes distinct biomechanics that shape how the shoulder moves and how the chest generates force. Interestingly, the muscle is also actively recruited as an accessory muscle of respiration when the shoulder and arms are stabilized! #medstudent #medicine #Anatomy #3DAnimation #MedicalAnimation
