Pectoralis Major Muscle | Origin | Insertion | Nerve supply | Actions.

The pectoralis major is the superior most and largest muscle of the anterior chest wall. It is a thick, fan-shaped muscle that lies underneath the breast tissue and forms the anterior wall of the axilla.
The pectoralis major is the most superficial muscle in the pectoral region. It is large and fan shaped, and is composed of a sternal head and a clavicular head:
Attachments:
Clavicular head - originates from the anterior surface of the medial clavicle.
Sternocostal head - originates from the anterior surface of the sternum, the superior six costal cartilages and the aponeurosis of the external oblique muscle.
The distal attachment of both heads is onto the intertubercular sulcus of the humerus.
Function: Adducts and medially rotates the upper limb and draws the scapula anteroinferiorly. The clavicular head also acts individually to flex the upper limb.
Innervation: Lateral and medial pectoral nerves.

What is the length of the tendon at the point of attachment to the humerus? And then in Google, in different pictures, the length of the tendons is different, and I can’t understand which of this is true
