The pectoral region is a part of the upper limb. It consists of several bones, including the pectoris major, pectoris minor, serratus, and teres major.
The pectoral region plays a significant role in the movement of the upper limb and is responsible for various functions, such as:
Rotation: The pectoris major and teres major bones allow for a wide range of rotations around the joints of the shoulder and elbow.
Flexion and extension: The pectoralis major and serratus bones contribute to bending the arm at the elbow joint, while the pectoralis minor and teres major bones extend the arm at the shoulder joint.
Abduction and adduction: The pectoralis major and teres major bones are involved in spreading the arm away from the body and adducting it toward the body, respectively.
Rotation: The pectoralis major and serratus bones also contribute to the rotation of the arm around the shoulder joint.
The pectoral region is a complex and essential region of the upper limb that enables a wide range of movements necessary for daily activities
