How Do You Spell PECTORALIS MUSCLES?

1. The pectoralis muscles, also known as the pecs, refer to a pair of prominent muscles located in the chest region of the human body. Specifically, the pectoralis muscles are large, fan-shaped muscles that cover the upper part of the ribcage. They extend from the sternum (breastbone) towards the shoulder joint on both sides and are responsible for the movement and stability of the shoulder and upper arm.

   Comprising two distinct muscles, the pectoralis muscles include the pectoralis major and pectoralis minor. The pectoralis major is the larger and more superficial muscle of the two, while the pectoralis minor lies underneath. The pectoralis major is primarily responsible for adduction (bringing the arm towards the midline of the body), flexion (moving the arm forward), and medial rotation (inward rotation) of the shoulder joint. Additionally, it contributes to other movements such as horizontal adduction, which involves bringing the arm across the chest. The pectoralis minor, on the other hand, assists in the stabilization and downward rotation of the scapula (shoulder blade).

   The pectoralis muscles are extensively used in activities that involve pushing, lifting, and throwing. They are notably important in various athletic disciplines, such as weightlifting, boxing, swimming, and throwing sports, as well as daily activities like carrying objects and pushing heavy doors. Regular strengthening exercises targeting the pectoralis muscles help enhance their function, improve overall upper body strength, and promote a balanced physique.
